Want to capture the digital eyewear market with confidence? Read on…

Below, we’ll guide you through the essentials of blue light glasses, frame and lens types, and exactly how to source them smartly from China — without the guesswork.

Part 1: What Are Blue Light Blocking Glasses?

Blue light blocking glasses — often called screen glasses or computer glasses — are designed to protect your eyes from the blue light emitted by digital screens like phones, laptops, and TVs. In today’s world, where people spend hours working, studying, and relaxing in front of screens, these glasses are becoming a daily essential.

So, What Exactly Is Blue Light?

Blue light is a type of high-energy visible (HEV) light that comes from both sunlight and digital screens. While not all blue light is bad, too much exposure — especially at night — can cause eye strain, headaches, blurry vision, and even trouble sleeping.

That’s where blue light glasses come in.

What Makes Blue Light Glasses Special?

Unlike regular glasses, blue light blocking glasses come with a special coating or lens material that filters out harmful blue light (typically in the 400–450nm range). They help people:

• Work longer on screens without eye fatigue
• Fall asleep easier by reducing melatonin disruption
• Protect their eyes from potential long-term damage

Some lenses are clear for everyday use, while others are yellow or amber-tinted for heavier screen users like gamers or night workers.

What Are They Made Of?

Most blue light glasses use:

• TR90 frames – super flexible and lightweight, perfect for all-day wear
• Polycarbonate or CR-39 lenses – durable and impact-resistant
• Blue light filtering coating – built into or layered on top of the lens
• Rubber or silicone nose pads – to keep the glasses in place comfortably

Why Your Customers Want Them

Whether it’s office workers, students, gamers, or kids doing remote learning — everyone wants a stylish pair of glasses that can protect their eyes while looking good. Blue light glasses are easy to market, affordable to produce, and increasingly in demand worldwide.

And that makes them a great product to wholesale and brand — especially when sourced smartly from China.

Part 2: Types of Blue Light Glasses

Not all blue light glasses are the same. Depending on your target customer — office workers, students, gamers, or kids — you’ll want to offer different styles, functions, and lens options. Below are the main types you’ll find when wholesaling blue light glasses from China.

1. Classic Everyday Blue Light Glasses (TR90 or Acetate)

These are the most common and versatile. They look like regular eyeglasses but come with a blue light filter.

•  Lightweight and durable
•  Ideal for office workers, students, or remote workers
•  Available in clear, neutral, or stylish frame colors
•  Great for bulk orders with logo customization

Perfect if you’re targeting a general audience who spends long hours on screens but still wants something comfortable and fashionable.

2. Metal + Acetate or TR90 Frames

For brands aiming at a premium or fashion-forward market, these frames combine metal arms with acetate or TR90 fronts for a high-end look.

•  Suitable for white-collar professionals
•  Ideal for private label collections
•  Often comes with anti-reflective and anti-smudge coatings

These are great for adding a modern, upscale touch to your blue light collection.

3. Amber or Yellow-Tinted Gaming Glasses

Gamers and heavy digital users often prefer stronger blue light protection — which is where tinted lenses come in.

•  Blocks a higher percentage of HEV blue light (up to 85%)
•  Amber or yellow tint enhances contrast and reduces glare
•  Lightweight, comfortable for long hours of wear

Perfect for e-sports brands, gaming shops, or screen-intensive work markets like video editors and coders.

4. Clip-On Blue Light Filters

For customers who already wear prescription glasses, clip-on blue light lenses are a practical, affordable add-on.

•  Magnetic or flip-up styles
•  Fits easily over optical frames
•  Popular with office workers or older users

These are a great upsell product or entry-level item in your wholesale offer.

5. Kids’ Blue Light Glasses

Kids today spend hours on tablets, online learning, and games — making blue light protection just as important for them.

•  Smaller sizes, flexible frames (TR90 or silicone)
•  Safe, chew-resistant, and bendable
•  Fun colors and cartoon-style designs available

If your market includes schools, pediatric opticians, or kids’ fashion, these are a must-have.

6. Blue Light + Prescription Glasses (RX Ready)

Many customers want both protection and vision correction in one frame. These allow for prescription lenses with blue light protection.

•  RX lens insert or full prescription option
•  Custom lens coating available per order
•  Ideal for optical stores or online prescription eyewear brands

Eyewearglobo supports OEM for prescription-ready blue light frames, starting from small MOQs.

7. Hybrid Safety + Blue Light Glasses

For factories, laboratories, or high-exposure workplaces with screens, these glasses combine eye protection with blue light filtering.

•  Often meet ANSI or CE safety standards
•  Ideal for industrial workplaces with digital devices
•  Strong frames with anti-impact lenses

A smart category for buyers selling to corporate, tech, or industrial clients.

How to Choose the Right Type?

When picking which types to wholesale, consider:

• Who is your end customer? (Adults, kids, professionals, gamers?)
• Where will the glasses be used? (Office, home, factory, gaming setups?)
• Do they need prescription options?
• Do they prefer style, function, or both?

The good news is: Chinese factories like Eyewearglobo offer all of these types — with flexible customization, private labeling, and MOQ starting from just a few hundred units.

Part 3: How to Wholesale Blue Light Glasses from China?

Step 1: Find Reliable Manufacturers

If you’re planning to wholesale blue light blocking glasses from China, your first step is to find a supplier you can truly rely on — one that not only offers good pricing, but also delivers consistent quality, clear communication, and on-time shipments.

Here are three proven ways to do that:

Use Google Search the Right Way

Start by using specific search terms like:

• “blue light glasses factory China”
• “OEM blue light eyewear manufacturer”
• “custom screen glasses wholesale China”

This can lead you to direct factory websites, not just trading companies. When you land on a potential supplier’s site, check if they:

• Clearly list blue light glasses as one of their main products
• Show photos of their actual factory or production lines
• Mention international certifications like CE, FDA, or ISO
• Provide clear contact info with a company domain email address

For example, Eyewearglobo is a verified manufacturer based in China with five production lines and a full focus on B2B eyewear orders, including blue light protection frames.

Explore B2B Platforms Like Alibaba and Made-in-China

These platforms are convenient for browsing product catalogs and comparing multiple suppliers in one place. However, not all listings are factories — some are middlemen or trading companies. To filter for real manufacturers:

• Use filters like “Verified Supplier” or “Own Factory”
• Look for suppliers with CE or FDA certifications listed in their product details
• Check minimum order quantities (MOQs) to make sure they fit your business needs
• Review ratings, response times, and how long the supplier has been active on the platform

Always send a clear inquiry and ask follow-up questions to confirm that the supplier actually produces the goods they list.

Attend Industry Trade Shows (In Person or Online)

Trade fairs are a great way to meet qualified eyewear manufacturers face-to-face or via video if you’re attending virtually. You can compare samples, learn about the latest materials and lens technologies, and build personal relationships with suppliers.

Recommended shows for eyewear sourcing include:

• Hong Kong Optical Fair
• Canton Fair (China’s largest export/import fair)
• MIDO (held in Italy, great for fashion and tech-focused eyewear brands)

Many reputable Chinese manufacturers showcase their newest blue light blocking styles at these events, and often offer trade show discounts or first-order deals.

Conclusion of Step 1

Whether you’re using Google, a B2B marketplace, or a trade show, the goal is the same: find a supplier who owns their production, understands your market, and offers transparent communication. Taking the time to choose the right partner will save you time, money, and stress down the road.

Step 2: Communicate Clearly with the Supplier

Once you’ve shortlisted a few potential manufacturers, the next important step is clear and professional communication. This is where many first-time buyers go wrong — sending vague messages, focusing only on price, or not explaining product details clearly.

To get accurate quotes and avoid future misunderstandings, here’s what you need to do:

Describe Exactly What You Need

Don’t just say “I want blue light glasses.” Suppliers in China work with many clients around the world, and each one may be looking for different specs. The more specific you are, the better your results.

In your first message, include the following:

• The frame material you prefer (e.g., TR90, acetate, metal)
• The lens features you need (e.g., blue light filter 400–450nm, anti-reflective coating, UV400, amber or clear lens)
• Whether you want ready stock, private label, or full OEM production
• If branding is needed (e.g., logo on temple, custom packaging)
• Target market and quantity range (this helps them recommend suitable models)

For example:
“We’re looking for TR90 blue light blocking glasses with CE and FDA certificates. Clear lenses with anti-reflective coating, and MOQ around 300–500 pieces. Logo printing and custom box packaging needed. Target market: USA.”

This kind of message shows the supplier you are serious and helps them reply with the right options.

Ask the Right Questions Upfront

A good supplier should be able to answer your key questions directly. Some things to ask early in the conversation include:

• Do you have CE/FDA certifications for these glasses?
• Can you provide actual blue light test results or videos?
• What is your typical production lead time for this model?
• What is the MOQ for custom branding?
• Do you offer a warranty or return policy for defective items?

If the supplier avoids answering or only gives general replies like “don’t worry,” this might be a red flag.

Clarify Communication and Time Zone Expectations

Many Chinese suppliers are responsive, but time zone differences can slow things down. To improve communication:

• Ask if you’ll have a dedicated sales representative
• Agree on a regular update schedule (e.g., twice a week)
• Use email for formal communication, and apps like WhatsApp or WeChat for quicker chats
• Keep your messages structured — use bullet points, attach product references, and avoid sending many scattered messages

Professional communication not only speeds up the process but also helps build long-term trust, which is key for repeat orders and better pricing in the future.

Conclusion of Step 2

The more clearly you explain your needs, the better your supplier can serve you. Clear communication helps avoid delays, quality issues, and unnecessary back-and-forth later on. In the end, it’s not just about finding the right product — it’s about building the right relationship.

Step 3: Ask for Factory Verification

Before placing any orders, it’s critical to make sure the supplier you’re talking to is a real manufacturer, not just a trading company pretending to be one. Verifying the factory early can help you avoid many risks — such as delays, poor quality control, or even fraud.

Here’s how you can do that effectively:

Request Factory Photos or Videos

Ask your supplier to send real pictures or short videos of:

• Their production lines (lens coating, frame assembly, packaging area)
• Office or design team
• Product showroom with blue light glasses on display

Factories that are legitimate and confident in their capabilities are usually happy to show their facilities. Be cautious if the supplier avoids this request or only shares generic stock photos.

Ask for Business Licenses or Certifications

You can request to see their:

• Business license (in Chinese, with company name and registration number)
• Export license
• ISO 9001 or similar quality management system certificate (if applicable)

If they already export to Europe or the US, they should also be able to provide CE and FDA-related certifications or documentation — especially for products like blue light glasses, which are often used for wellness or eye protection.

Check for Existing Export Experience

Ask directly:

• How long have you been manufacturing blue light glasses?
• What countries have you exported to before?
• Do you have repeat clients in Europe, North America, or Southeast Asia?

An experienced supplier will often mention their main export markets, and sometimes offer to connect you with a reference client.

Google Their Company Name and Cross-Check

Do a background check by searching their:

• Company name + “review” or “scam”
• Company name + “eyewear factory”
• Company name + “site:linkedin.com” (to see staff or company profiles)

You might be surprised how much useful info you can find this way, including whether the company is listed on business directories, involved in trade shows, or has real people behind the brand.

Consider a Video Call or Third-Party Audit

If you’re about to place a large or custom order, it’s worth taking one of these extra steps:

• Schedule a video call to see their office or factory live
• Hire a local third-party inspection company (like SGS, BV, or TÜV) to visit their facility

This small investment can save you from major losses later, especially if you’re planning to build a long-term partnership or launch a private label line.

Conclusion of Step 3

Factory verification is about more than trust — it’s about reducing risk and protecting your investment. The more you know about your supplier’s real capabilities, the more confidently you can move forward with your wholesale order. And with reliable suppliers like Eyewearglobo, factory tours and documentation are always available upon request.

Step 3: Ask for Factory Verification

Before placing any order, it’s important to confirm whether your supplier is a real factory or just a trading company. Both types of suppliers exist in China’s eyewear market, and each has its pros and cons — but you need to know who you’re really dealing with.

Factory vs. Trading Company: What’s the Difference?

Factories are best when:

• You want to develop your own brand
• You need full customization (frames, lenses, packaging)
• You’re ordering in bulk and want to control costs

Trading companies are useful when:

• You need a mix of different product styles in one order
• You’re placing small trial orders or testing the market
• You want smoother communication and don’t mind slightly higher prices

For example, Eyewearglobo is a factory supplier — meaning we handle everything in-house, from lens coating to frame injection to packaging. But we also have a professional export team, giving you the best of both worlds: factory pricing + smooth communication.

How to Verify Your Supplier’s Type

If the supplier claims to be a factory, ask for:

• Photos or videos of their production lines (assembly, lens cutting, QC station)
• Their Chinese business license, showing “manufacturer” in their business scope
• A video call or live showroom tour

If they’re a trading company, they should be upfront about it. Some trading companies are very professional and have long-term relationships with excellent factories — but the key is transparency.

Why Verification Matters

Without knowing who you’re dealing with, you risk:

• Paying too much for low-quality goods
• Losing control over production timelines
• Facing delays during peak seasons
• Having no support when things go wrong

If you plan to grow your eyewear brand, factory partnerships usually offer better long-term stability, better pricing, and more room to scale.

Consider a Simple Background Check

Here are a few ways to verify any supplier:

• Search their company name on Google, Alibaba, and LinkedIn
• Look for trade show participation (like Hong Kong Optical Fair, MIDO)
• Ask for previous client references or export documents
• Use a third-party inspection service to verify their location and equipment

Conclusion of Step 3

Whether you choose a factory or a trading company depends on your business needs — but you should always know who you’re dealing with before you place an order. A trusted factory like Eyewearglobo gives you full control over production, customization, and timelines, with the added bonus of an experienced export team to support your growth.

Step 4: Request Product Certifications

Before you get too deep into pricing or samples, take a moment to ask this simple question:
“Do your blue light glasses have the right certifications?”

Even though blue light glasses aren’t classified as medical devices, many buyers — especially in the US and Europe — expect certain certifications as proof of quality and compliance. And if you’re planning to build a serious eyewear brand, you’ll want these documents ready.

The Core Certifications to Ask For

Here are the most common ones:

• CE (Europe): This shows that the product meets European health and safety standards. Even if it’s not legally required, it gives peace of mind to your customers and retailers.
• FDA (USA): Not mandatory for all eyewear, but it’s a big plus if you’re selling in the U.S. — especially for functional lenses.
• ISO: This usually refers to the factory’s internal quality control systems, like ISO 9001. It tells you they have a structured production process, not just doing things on the fly.

If your supplier can’t provide at least CE or FDA for blue light glasses, it’s a red flag — they may be producing only for local markets or lack experience in exporting compliant goods.

What About Blue Light Test Reports?

You should also ask for a blue light lens spectrum test report.

This shows how much of the harmful blue light (typically 400–450nm) the lens actually blocks. Many suppliers say “blue light blocking,” but unless there’s proof, it could just be a yellow-tinted coating with no real effect.

Even better, ask them to send a demo video — many Chinese suppliers will shine a blue light pen through the lens to show how well it blocks the light. It’s simple but very effective for visual confirmation.

Look for Third-Party Lab Testing (Optional but Strong)

If your brand is aiming for higher-end retailers, marketplaces like Amazon, or even optical chains, third-party testing adds credibility. Some suppliers will have past reports from labs like:

• SGS
• BV (Bureau Veritas)
• TÜV Rheinland

These reports are often conducted on specific models or lens batches, so ask whether they have recent examples that match what you plan to order.

Note: These certifications are optional and might not be available for every low-MOQ order, but it’s still worth asking.

How to Ask for Certifications (Without Sounding Difficult)

Don’t overthink it. Just ask directly:

• “Do you have CE or FDA certification for your blue light models?”
• “Can you provide a lens spectrum test or demo video?”
• “Have any of your products been tested by SGS, TÜV, or similar labs?”

If they can send the files immediately or show you test results, that’s a good sign they know what they’re doing. But if they avoid the question, make excuses, or delay again and again — it may be safer to look elsewhere.

Quick Summary:

Blue light glasses are functional eyewear. Certifications aren’t just paperwork — they’re your proof of performance.
If you want to build a professional brand, sell to serious retailers, or just protect your business reputation, this step isn’t optional. It’s essential.

Step 5: Negotiate Pricing and MOQ

Once you’ve confirmed the supplier is legit and the certifications check out, it’s time to talk business: pricing, MOQ (Minimum Order Quantity), and all the little extras that can impact your final cost.

Many buyers rush into this step, but smart negotiation is where you protect your margins and avoid nasty surprises later.

Understand the Typical MOQ Structure

For blue light glasses, here’s what you can usually expect:

• Ready stock (no logo): MOQ starts from 100–200 pieces per model
• Custom logo on temples or packaging: MOQ is usually 300–500 pieces
• Full OEM (custom design, materials, lens upgrades): MOQ can be 1000 pieces or more

If a supplier agrees to very small quantities with full customization, be cautious — they may not control the production and could be outsourcing everything.

It’s okay to ask for smaller trial orders, but don’t expect full customization at the lowest MOQ. Good suppliers will offer tiered pricing based on quantity — the more you order, the better the price.

What’s Included in the Price?

When you receive a quote, ask what’s actually included. For blue light glasses, here are things that may or may not be part of the unit price:

• Blue light blocking lenses (clarify if it’s clear or tinted)
• Anti-reflective or UV400 coating
• Frame color or pattern options
• Logo printing (on frame, lens, case)
• Microfiber pouch or hard case
• Custom packaging or inserts

You should also ask if the price includes shipping to your port (FOB), or if it’s just the factory price (EXW). This makes a big difference in your landed cost.

Ask the Right Questions to Avoid Hidden Costs

Here’s a simple checklist you can use in your email or chat:

• “Is logo printing included in the price?”
• “Is the quoted price based on EXW or FOB terms?”
• “Is packaging standard or custom?”
• “Are the lenses coated with AR or just basic blue light filter?”
• “Can I mix colors in one order?” (Important if you want variety but low volume)

Suppliers appreciate direct and structured questions — it saves time on both sides.

Negotiate Like a Partner, Not a Bargain Hunter

If you’re serious about building a long-term relationship, don’t start by pushing the price down aggressively.

Instead, try this approach:

• Start with: “This is our first test order, and we plan to reorder monthly if quality and service are good.”
• Ask: “Is there any discount for repeat customers or orders above 1000 units?”
• Or say: “We’re comparing a few suppliers and looking for best total value, not just price — what flexibility can you offer?”

Most suppliers will work with you if they see you’re a potential repeat client. You might get better terms on packaging, free samples on the next order, or small upgrades without extra charges.

Don’t Forget to Ask About Return & Replacement Policy

Before you place an order, ask:

• “What happens if some units arrive damaged?”
• “Do you offer a replacement policy for defects?”
• “What’s your quality standard for acceptable rates (e.g., <1% defect)?”

Reputable suppliers like Eyewearglobo typically offer a limited warranty or product guarantee — especially for bulk orders. Make sure everything is agreed in writing, even in email.

Quick Summary:

Negotiating isn’t just about squeezing the price — it’s about knowing what you’re getting and building a supplier relationship that can scale with your business.
Be clear, be fair, and focus on long-term value — and you’ll often get better deals than those just chasing the lowest price.

Step 6: Place Your Order

Once you’ve confirmed the product details, pricing, and MOQ, and you’re happy with the terms — it’s time to make things official.

Placing an order with a Chinese supplier isn’t just about sending a “yes” over email. You need to lock in all the important details on paper, or you might end up with surprises you didn’t expect.

Always Use a Proforma Invoice (PI)

Before you pay anything, your supplier should issue a Proforma Invoice — basically a contract that confirms what both sides have agreed to. Don’t treat this as just a formality. This is your main protection if anything goes wrong later.

A good PI should include:

• Product details (model, frame material, lens type, features)
• Quantity and unit price
• Total amount and currency
• Customization info (logo, packaging, coating)
• Production lead time
• Delivery terms (EXW, FOB, CIF, etc.)
• Payment terms (e.g. 30% deposit, 70% before shipping)
• Bank details for payment

Take your time to review everything. If something is missing or vague, ask them to revise it. It’s easier to correct now than after money has changed hands.

Confirm All Specs in Writing — No Verbal Promises

Sometimes a supplier might say things like “Don’t worry, we’ll follow your requirements” or “It’s standard.” But unless it’s written into the PI or email thread, it doesn’t count.

To avoid misunderstandings, make sure all important details are confirmed in writing:

• Frame color and finish
• Lens style (clear, amber, anti-reflective, UV400, etc.)
• Logo position and size
• Packaging (type, design, materials)
• Accessories (pouch, case, cloth)
• Delivery date (not just “around 3 weeks” — be specific)

You can even ask the supplier to summarize your customization requirements in bullet points and attach it to the PI as an “Order Confirmation Sheet.”

Set a Realistic Lead Time

Most blue light glasses orders (with customization) take 20–30 days to produce. Stock orders or no-logo samples may be ready in 5–7 days.

Don’t forget to ask:

• “When will production start — after deposit or final design approval?”
• “Can you send updates during production?”
• “What’s the earliest shipping date you can commit to?”

Setting clear expectations now prevents last-minute delays — especially if you’re preparing for a seasonal launch or retail campaign.

Bonus Tip: Confirm Sample Approval Before Mass Production

If this is your first order or a custom product, it’s a good idea to ask for a pre-production sample or a detailed sample photo/video before they start the full run. Even if you’ve already received a prototype, a quick reconfirmation helps catch small changes (logo size, frame texture, lens clarity) before it’s too late.

Quick Summary:

Once you’re ready to order, don’t rush the paperwork. Get a clear Proforma Invoice, confirm all specs in writing, and agree on a realistic timeline.
A few extra steps here can save you a lot of stress (and money) later — especially if this is the beginning of a long-term partnership.

Step 7: Make a Deposit

Now that you’ve signed the Proforma Invoice and confirmed all details, it’s time to make the initial payment so the supplier can start production.

In most cases, Chinese suppliers follow a “30/70” payment term:

• 30% deposit to confirm the order and begin production
• 70% balance paid before shipment (after quality inspection)

This is standard practice and accepted globally for B2B wholesale orders.

How to Pay Securely

For first-time transactions, it’s perfectly normal to feel cautious about sending money internationally. Here are the safest and most common methods:

1. T/T Bank Transfer (Telegraphic Transfer)
   • The most widely used method for bulk orders
   • Make sure the bank details match the company name on the PI
   • Double-check the SWIFT code and account number before sending
2. Alibaba Trade Assurance (if working through Alibaba)
   • Offers added protection for buyers
   • Payment is held until you confirm shipment or quality approval
   • Ideal for trial orders or first-time suppliers
3. PayPal or Wise (only for small sample orders)
   • Convenient for quick sample payments under $500
   • Not recommended for full bulk orders due to high fees and weak protection

Ask for a Payment Confirmation

After sending the deposit, ask the supplier to confirm:

• The amount received
• The expected production start date
• The timeline for production updates

You can simply write:
“Please confirm once the deposit is received and let me know when production will begin.”

A reliable supplier should respond quickly and keep things transparent.

Important Tip: Always Pay the Company, Not a Personal Account

Never send your deposit to a personal bank account or an account with a different name than the company listed on the invoice — that’s a major red flag. Payments should always go to the company’s official business account. If you’re unsure, ask for a business license to verify the company name.

Quick Summary:

Making a deposit is the first financial step in your wholesale journey. Stick to standard 30/70 terms, pay through secure channels, and always double-check bank details.
Clear communication and payment confirmation now will help avoid confusion and build trust as production begins.

Would you like me to continue with Step 8: Product Inspection? We’re moving into the quality control and delivery phase next — very important for protecting your brand. Ready when you are!

Step 8: Product Inspection

You’ve placed your order, the factory is working on production, and everything seems to be going smoothly — but don’t relax just yet.
Before you pay the final balance or ship the goods, you need to make sure the products meet your standards.

This is where quality control (QC) comes in.

Why Inspection Matters

Even the best factories can make mistakes — maybe the wrong frame color was used, the lens isn’t blocking enough blue light, or the logo was printed off-center. Once the goods are shipped, fixing those issues gets expensive and time-consuming.

A proper inspection helps you:

• Catch mistakes early
• Protect your brand reputation
• Avoid returns and refund requests from your customers
• Build a healthy, professional relationship with your supplier

Three Ways to Inspect Your Order

1. Ask for Pre-Shipment Samples
Before the full batch is packed, ask your supplier to send you 1–2 finished units from your order. These should include all your customizations — logo, packaging, coatings, etc.
Once you receive the samples, test them yourself for lens clarity, comfort, and blue light effectiveness.

If you’re short on time, you can also ask for detailed photos and videos instead.

2. Hire a Third-Party Inspection Company
There are many inspection services in China (like SGS, BV, or local agents) that can visit the factory, inspect your order, and send you a full report. They check:

• Product quantity and packaging
• Frame and lens details
• Logo accuracy
• Functional tests (e.g., blue light filtering with a pen light)
• Overall appearance and defects

The cost is usually around $100–300 depending on the order size and location — a smart investment for bulk orders or new suppliers.

3. Do a Video Call Walkthrough
If you trust the supplier but want some extra assurance, schedule a live video call. Ask them to show:

• Randomly selected finished products
• Packaging setup
• Lens performance with a blue light test
• Shipping cartons and labels

It’s quick, free, and gives you more control than just waiting and hoping.

What to Test for Blue Light Glasses

Here’s a simple checklist you or your inspector should go through:

• Are the frame colors and shapes as ordered?
• Is your logo printed correctly and cleanly?
• Do the lenses block blue light in the correct range (400–450nm)?
• Is the anti-reflective or UV400 coating clearly visible?
• Is the packaging correct (custom box, pouch, cloth)?
• Any scratches, loose screws, or damaged parts?

What If Something’s Wrong?

Mistakes happen — the key is how the supplier responds.

• If issues are minor (e.g., missing logo on a few pieces), negotiate a partial refund or remake for the affected units.
• If the problem is serious (e.g., wrong lens type or low-quality coating), don’t pay the final balance yet. Ask the supplier to remake or repair before shipping.

Good suppliers like Eyewearglobo will typically offer a clear after-sales policy and work with you to resolve any QC issues.

Quick Summary:

Never skip inspection. Whether it’s a small trial order or a full container, a simple check before shipping can save you thousands.
Whether you inspect personally, hire a third party, or do a video call — just make sure you’re not shipping blind.

Step 9: Final Payment

Once your order passes inspection and you’re satisfied with the results, it’s time to make the final payment. This is usually the remaining 70% of the total order amount — unless you’ve agreed on a different payment term.

But don’t rush this part — a few checks before paying can save you from big headaches later.

Double-Check Everything Before You Pay

Here’s what to confirm before sending the balance:

• You’ve received photos or videos of the final packed products
• Pre-shipment samples (if applicable) match your approved version
• The supplier has confirmed everything is ready to ship — including packaging, accessories, and labeling
• You’ve received an updated Commercial Invoice with the final amount and shipping details

If you’ve hired a third-party inspector and they gave you the green light, make sure to read their report carefully — not just the summary. If something doesn’t feel right, don’t be afraid to ask questions or request corrections before paying.

Use the Same Secure Payment Channel

You should use the same bank account and payment method you used for the deposit. If the supplier suddenly gives you a new account — especially one under a different company name — pause and verify.

To be safe:

• Ask: “Is this the same account as before?”
• If it’s different, ask for an updated business license or official explanation
• Confirm via video call or company email — never confirm sensitive payment details over random WhatsApp messages

Scams can and do happen, especially when dealing with large amounts. Always be cautious.

Get a Payment Receipt & Shipping Timeline

Once you send the money, ask the supplier to:

• Confirm the amount received
• Send a receipt or bank confirmation slip
• Give you the exact shipping schedule (date of vessel or air freight departure)

This keeps everyone on the same page and avoids miscommunication.

Optional: Use Payment Terms for Long-Term Orders

Once you’ve built trust with a supplier over multiple orders, you may be able to negotiate better payment terms, like:

• 30% deposit / 70% after goods arrive
• 100% payment after inspection
• Payment via letter of credit for large volumes

This usually comes with time and relationship-building, but it’s worth aiming for if you plan to scale up.

Quick Summary:

Final payment means you’re officially closing the production phase — but don’t treat it as just “sending money.”
Confirm everything, keep payments secure, and make sure your supplier is fully aligned on the shipping timeline.
A smooth payment now sets the tone for a strong delivery process.

Step 10: Get Ready to Import

You’ve approved the products, paid the final balance — now it’s time to get those blue light glasses from the factory floor in China to your doorstep.
This part can feel overwhelming, especially if you’re new to international shipping, but once you understand the basics, it becomes a smooth routine.

Choose the Right Shipping Method

There are three main ways to ship your goods from China:

1. Air Freight
Best for: Small to medium-sized orders (1–3 cartons), urgent timelines

• Delivery time: Around 5–10 days
• Cost: Higher than sea freight, but much faster
• Carriers: DHL, UPS, FedEx, or air cargo through freight forwarders

2. Sea Freight
Best for: Large-volume orders (500+ units or full cartons), lower urgency

• Delivery time: 25–45 days (depending on destination and port traffic)
• Cost: More affordable for bulk shipments
• Suitable for container loads or LCL (less than container load)

3. Courier Shipping
Best for: Samples or very small orders (under 20kg)

• Delivery time: 4–7 days
• Carriers: DHL, FedEx, EMS
• Easy to handle but expensive per unit

Tip: If you’re not sure which to choose, ask your supplier or a freight forwarder to quote both air and sea options — then compare time vs. cost.

Understand Incoterms (Shipping Terms)

When you receive a quote, you’ll often see terms like EXW or FOB — these define who is responsible for what in the shipping process.

Here’s what they mean:

• EXW (Ex Works): You handle everything from pickup at the factory to delivery. Best for experienced importers who have their own logistics partner.
• FOB (Free on Board): The supplier delivers the goods to the nearest port in China. From there, you or your forwarder manage the shipment. This is a common and safe choice for most buyers.
• CIF (Cost, Insurance & Freight): Supplier handles shipping to your port, including freight insurance. You just clear customs on your side.

If you’re just starting out, FOB is usually the most balanced and manageable.

Work with a Freight Forwarder

A freight forwarder is a logistics partner that helps you handle shipping, customs, and delivery from China to your country. You can either:

• Use your own forwarder (if you have one already), or
• Ask your supplier to recommend someone they trust — many factories work with reliable agents daily

A good freight forwarder will:

• Give you clear pricing (air vs sea)
• Handle export documents (bill of lading, packing list, invoice)
• Guide you on customs clearance and import taxes
• Help you avoid costly mistakes like missing documents or delays at the port

Plan Around Delivery Times

This part is often underestimated. If your blue light glasses arrive too late for a planned launch or retail season, you lose sales — period.

Plan backward from your desired in-store or campaign date, and account for:

• Production time
• Shipping duration
• Customs clearance and local delivery
• Unexpected delays (weather, port congestion, holidays)

If you’re targeting specific seasons like Back to School or Black Friday, talk to your supplier early and schedule your shipment ahead of time.

Quick Summary:

Shipping doesn’t need to be scary. Choose the method that fits your budget and timeline, understand your shipping terms (FOB, EXW), and work with a freight forwarder you trust.
Get your delivery timing right, and you’ll stay ahead of the market — not scrambling to catch up.

Step 11: Track Your Cargo

Once your blue light glasses leave the factory, the production part is done — but your job isn’t.
Now it’s time to track your shipment and get everything ready on your side for customs clearance, storage, or distribution.

Whether you shipped by air or sea, having visibility into where your cargo is (and when it’s expected to arrive) is key to avoiding delays and lost sales.

Ask for Tracking Documents Right Away

After your supplier hands over the goods to the freight company, ask for the following:

• Tracking number or airway bill (for air/courier shipping)
• Bill of Lading (for sea freight)
• Packing list and Commercial Invoice
• Estimated Time of Arrival (ETA) at your destination port or airport

These documents help you:

• Track the shipment’s real-time location
• Start preparing customs paperwork (or give them to your broker)
• Plan delivery to your warehouse or fulfillment center

If you’re working with a freight forwarder, they’ll usually email you updates automatically. But you should still check in regularly to stay ahead of any delays.

Tools to Track Your Shipment

Depending on how your goods were shipped, here are a few ways to track them:

• Courier (DHL, FedEx, UPS): Use the tracking number directly on their websites
• Air Freight: Use the Air Waybill (AWB) number and track through sites like track-trace.com
• Sea Freight: Track using the Bill of Lading number and the shipping line’s website (e.g., Maersk, COSCO, MSC)

Some platforms also offer cargo visibility dashboards, especially if you ship regularly.

What to Do If There’s a Delay

Delays happen — port congestion, customs backlog, or even weather can throw off your ETA. Don’t panic, but be proactive:

• Ask your freight forwarder for an updated timeline
• Inform your warehouse or receiving team in advance
• If you’re selling online, adjust your store’s delivery estimates to avoid customer complaints

And if the delay is serious (e.g. missing a retail campaign), contact your supplier about partial air shipment of urgent units — some are willing to split shipments in special cases.

Start Prepping for Arrival

As soon as you get your ETA, start preparing for what comes next:

• Customs clearance documents
• Final payment of duties or taxes (if not handled by your forwarder)
• Storage space or shelf prep in your warehouse
• Marketing materials or product listings (for online sellers)

If you’re importing into countries like the USA, EU, Canada, or Australia, your freight forwarder or customs broker can guide you on what import codes or documentation are needed.

Quick Summary:

Your job doesn’t end when the products ship. Stay in touch with your freight partner, track your cargo closely, and prepare for a smooth arrival on your end.
Good tracking = no surprises = happy customers.

Step 12: Handle Delayed or Damaged Goods

Even if you’ve done everything right — inspected the goods, picked a trusted forwarder, planned your timelines — things can still go wrong in transit.
Shipping delays, broken frames, crushed packaging — it happens. But don’t panic. What matters is how you handle it quickly and protect your business.

Common Issues You Might Face

1. Shipping Delays
   • Port congestion
   • Customs backlog
   • Holiday closures in China or your country
   • Missed transshipment connections
2. Damaged Goods
   • Scratched lenses
   • Broken frames
   • Bent temples
   • Packaging dented or soaked
3. Lost or Missing Cartons
   • Partial delivery
   • Items “stuck” in customs or returned to origin

These situations aren’t fun — but they’re fixable if you follow the right steps.

Step 1: Keep All Documentation and Photos

When a problem happens, evidence is everything. Right away:

• Take clear photos of any damaged products or packaging
• Save tracking records and delivery reports
• Ask your freight forwarder for the full shipping file (bill of lading, insurance, invoices)
• Document dates, quantities, and any conversations with the courier or logistics company

This will be essential if you need to file a claim or negotiate with your supplier.

Step 2: Check If You Have Shipping Insurance

If you arranged shipping under CIF terms or added insurance through your freight forwarder, you’re likely covered for damage or loss during transit.

What you can do:

• Contact the insurance agent or freight forwarder to open a claim
• Provide all documentation and proof
• Expect to wait 2–6 weeks for a resolution (depending on the case)

If no insurance was purchased, you may need to discuss compensation directly with your supplier — especially if the damage is related to poor packaging.

Step 3: Contact Your Supplier Immediately

Reach out to your supplier with:

• A detailed list of what was damaged or delayed
• Photos or videos as proof
• A clear request: Are you asking for a refund, replacement, or credit toward your next order?

A good supplier (like Eyewearglobo) will want to protect their relationship with you and will often offer:

• Free replacements in your next shipment
• Partial refunds or credit
• Improved packaging for future orders

Make sure any agreement is put in writing, even if it’s informal. That way, there are no misunderstandings later.

Step 4: Learn and Improve for the Next Shipment

Every shipping issue is a lesson. Ask yourself:

• Could better packaging have prevented this?
• Should I start adding insurance for all orders?
• Was this forwarder reliable, or do I need a new one?
• Should I plan more buffer time before seasonal campaigns?

Most experienced importers run into at least one of these issues — the smart ones just build better systems to reduce the risk next time.

Quick Summary:

Delays and damage happen. What matters is how fast you act, how well you document it, and how good your supplier is at standing behind their products.
Stay calm, be organized, and turn the situation into a stronger process for future orders.

Step 13: Transport to Your Warehouse

Your shipment has landed. It’s cleared customs. Now it’s time for final delivery — from the port or airport to your warehouse, fulfillment center, or retail location.

This part might seem simple, but if not handled properly, it can lead to unnecessary delays, extra costs, or product damage. Let’s go through what to expect and how to stay in control.

Step 1: Choose Your Final Delivery Option

Depending on your setup and shipment size, here are your main options:

• Local freight or trucking company – Good for pallet-sized or bulk shipments arriving by sea
• Courier service – For smaller air shipments or carton-sized deliveries
• 3PL (Third-Party Logistics Provider) – If you’re storing inventory in a fulfillment center or need warehousing support
• Self-pickup – If you’re nearby and want to save on delivery fees

If you’re using a freight forwarder, they’ll usually coordinate the local delivery — but make sure you confirm the delivery address, contact person, and unloading setup ahead of time.

Step 2: Prepare Your Receiving Location

Here’s what to have ready before the truck or courier shows up:

• Warehouse staff notified and scheduled
• Loading/unloading space cleared
• Forklift or pallet jack ready (if needed)
• Paperwork (bill of lading, invoice, packing list) printed and on hand
• A person responsible for receiving and checking the goods on arrival

Even if your order isn’t huge, having someone check for visible damage or missing boxes right at delivery can prevent disputes later.

Step 3: Do a Quick Internal Check

Once your shipment is inside your facility, open a few boxes to check:

• Is the packaging intact?
• Are the frame colors and logos correct?
• Any signs of lens scratches, loose screws, or poor finishing?
• Does the quantity match what was listed on the packing list?

You don’t have to inspect every unit — just a random sample from each style or SKU. This is especially useful if you’re reselling to retailers or shipping to end customers.

Step 4: Store Your Glasses Properly

Blue light glasses aren’t fragile like electronics, but they still need clean, organized, and dry storage. Here’s what to keep in mind:

• Avoid direct sunlight or high heat (can affect lens coating)
• Keep styles and SKUs labeled clearly for faster order processing
• If storing in a 3PL warehouse, confirm that all units are scanned and logged correctly
• Rotate inventory regularly if you’re managing large volumes

If you plan to repack or rebrand the products (like adding inserts or flyers), now is the time to do it.

Bonus Tip: Prepare for Returns or Defects

No matter how good your supplier is, a few defective pieces can slip through. Keep a simple return or replacement policy in place for your retailers or customers.

For example:

• Allow returns within 30 days for obvious defects
• Keep 1–2% extra units as buffer stock for replacements
• Notify your supplier if you receive any patterns of defects — they may offer credit or remake

Quick Summary:

Final delivery and warehouse receiving may seem like the easy part, but small mistakes here can cost you time and money.
Plan ahead, check your shipment on arrival, and make sure your storage process is organized — especially if you’re scaling your business.

Step 14: Confirm Warranty and After-Sales Service

Once the goods are delivered and stored, most buyers think the process is over. But smart wholesalers know the job isn’t really finished until one last thing is in place:

A clear warranty and after-sales service agreement.

Why? Because even if your first order goes smoothly, you need to prepare for real-world situations — like a few defective pieces, customer returns, or a new order that needs urgent follow-up.

Let’s talk about how to lock in proper after-sales support.

Step 1: Ask About the Supplier’s Warranty Policy

Good suppliers — especially factories that care about long-term partnerships — will offer some kind of warranty or product guarantee.

Common warranty terms for blue light glasses include:

• 3–6 months coverage for manufacturing defects
• Replacement or credit for broken frames, loose hinges, or misprinted logos
• Limited coverage for coating issues (e.g. anti-reflective peeling or discoloration)

Here’s how you might ask:

“Do you offer any warranty on your blue light glasses for quality issues after delivery?”
“What happens if we find some defective pieces during unpacking or customer returns?”

If the supplier avoids the question or says “no warranty,” that’s a red flag — especially if you’re placing larger orders.

Step 2: Agree on a Process for Handling Issues

You don’t need to overcomplicate things. Just agree on a simple, clear process for reporting and resolving product issues:

• You’ll send photos or videos of any defective units
• You’ll keep a count and report within a reasonable time frame (e.g. 30 days after delivery)
• The supplier will offer a solution: remake, refund, or credit toward the next order

You can document this agreement by email, or ask them to include a line in your PI or invoice.

Step 3: Test Their After-Sales Support on Small Things

Even before anything goes wrong, you can “test” how good their service is.

For example:

• Ask a simple follow-up question after the order ships — do they still reply quickly?
• Ask for an extra copy of the invoice or packing list — are they still helpful after they’ve been paid?
• In your second order, ask for a small change or improvement — are they flexible?

Suppliers like Eyewearglobo often stand out in this area: their after-sales service includes email support, claim tracking, and flexible compensation for verified quality issues.

Step 4: Build a Long-Term Relationship

The best warranty isn’t just written in terms — it’s built over time through trust and communication.

If your supplier knows you’re a repeat customer who pays on time and communicates professionally, they’re much more likely to:

• Prioritize your orders
• Offer better pricing on future batches
• Be flexible with small issues or urgent requests
• Help you develop new styles or branded packaging

So don’t treat after-sales as just damage control — it’s the foundation for growth.

Quick Summary:

Warranty and after-sales support aren’t just “nice to have” — they’re essential for protecting your brand and keeping your customers happy.
Make sure your supplier stands behind their product, agrees on how to handle issues, and continues to support you after the sale, not just before.

FAQ: Sourcing Blue Light Glasses from China — What Smart Buyers Want to Know

1. What are the top blue light glasses manufacturers in China for B2B buyers?

Some well-known suppliers include:

• Eyewearglobo (factory-based, supports custom and ready stock)
• Wenzhou Merson Optical (specializes in mid-range ODM models)
• Xiamen Lens Technology (focus on lens coatings and RX production)
• Shenzhen Feirong Optical (large-scale production with global clients)

Tip: Look for manufacturers that own their production lines and can provide CE/FDA certifications.

2. Are Chinese-made blue light glasses as good as brands like Felix Gray, JINS, or Gunnar?

Yes — in fact, many Western DTC brands source directly from Chinese factories.
The key difference is often in branding, packaging, and marketing, not lens performance.

If you choose a factory with real lens-coating capabilities, like Eyewearglobo, you can get products with:

• 30–85% HEV filtration
• Anti-reflective coating
• UV400 protection
• Options for prescription blue light lenses

Some Chinese OEM factories are behind well-known Western eyewear brands — they just don’t put their name on it.

3. How can I compare Chinese suppliers without flying to China?

Try this multi-step comparison method:

Most serious buyers use video calls + samples + third-party QC instead of physical visits now.

4. What brands already use Chinese blue light glasses suppliers?

While brand partnerships are usually confidential, many recognizable names in e-commerce and retail source from Chinese factories, including:

• Amazon FBA brands (e.g., SOJOS, Livho, TIJN)
• Private label optical shops in the US, UK, EU
• Gaming eyewear brands (e.g., esports teams rebranding stock frames)
• Corporate wellness companies (bulk orders for office staff)

China is the go-to source for companies that want good margins with solid quality.

5. What’s the biggest risk when importing blue light glasses from China — and how do I avoid it?

Top risks include:

• Fake certifications or low-performing lenses
• Poor communication (missing custom details, wrong packing)
• Missed deadlines (especially before back-to-school or holiday season)

How to avoid:

• Work with a factory that shows real lens performance (not just yellow tint)
• Confirm every spec in writing before paying deposit
• Schedule inspection before shipment
• Start with a small trial order (Eyewearglobo accepts 100–300 pcs)

6. How do Chinese blue light lenses compare to Japanese or Korean lenses?

In general:

If you’re selling mid- to high-range blue light glasses, China offers the best balance between performance and cost — especially for private label.

7. Can I use a Chinese supplier to build my own blue light eyewear brand?

Yes — many factories offer full private label services, including:

• Custom frame colors, materials, and shapes
• Printed logo (on lens, temples, packaging)
• Custom box, pouch, cloth, and inserts
• Support for e-commerce packaging (barcode, inner carton labels)

Eyewearglobo supports private label from 300–500 pcs and helps new brands scale up over time.

8. How much should I budget per unit for wholesale blue light glasses?

Final price depends on materials, coatings, packaging, and freight. Request detailed quotes for accurate budgeting.
