Knowing where Chinese eyewear is produced is only half of sourcing. The other half is knowing where to meet suppliers and how to tell a serious manufacturer from a good-looking booth or a polished profile. Buyers today have more channels than ever: trade shows, social media, search engines and B2B marketplaces. Each has strengths, and none is enough on its own.
This guide explains the main channels, with a focus on eyewear trade shows in China, and gives a practical way to vet suppliers wherever you find them. Show details are taken from organizers and published listings, and are given with their year, because dates, venues and scale change from edition to edition. Always confirm current details on the official fair website before you plan a trip.
A trade show puts many suppliers in one place for a few days. For a buyer, that offers several advantages that are hard to get from a screen:
• Comparison. You can compare many suppliers' products side by side in a short time.
• Direct conversation. Owners, sales managers and technical staff are often at the booth, so you can ask detailed questions directly.
• Hands-on evaluation. You can handle frames, check finishing, hinges and color, and collect samples on the spot.
• First impressions. A booth shows how a company presents itself, how it answers questions and how it handles a new contact.
A fair is a starting point, not proof of capability. A good booth does not guarantee a good factory, so the vetting steps later in this guide still apply.
China hosts several optical fairs each year. The four below are the best known for frames. Figures are the organizers' or listing figures for the years shown.
SIOF is held at the Shanghai New International Expo Centre. The 24th edition was scheduled for 2–4 March 2026. According to the listing, the previous edition in 2025 had 971 exhibitors from 23 countries and regions and 140,000 visitors from 95 countries and regions. Exhibit categories include frames, sunglasses, sports and reading glasses, lenses, spare parts, cases, safety eyewear and eye care products.
Best for: buyers who want a very broad view of the industry, from frames to lenses and accessories, in one visit.
The Wenzhou fair has run since 2003, according to its organizer. The 24th edition was scheduled for 8–10 May 2026 at the Wenzhou International Convention and Exhibition Center. The organizer describes eight themed pavilions covering finished eyewear, lenses, accessories and eye health products, and states more than 700 exhibitors for the 2026 edition. These are the organizer's own figures.
Best for: buyers interested in the Wenzhou production base and a large choice of frame suppliers.
CIOF is held at the China International Exhibition Center in Beijing, organized by the China Optometric & Optical Association and Sinolight International Holdings. The 2026 edition was scheduled for 8–10 September. The most recent figures listed are for 2025, with 693 exhibitors and 58,000 visitors. The scope covers frames, lenses, accessories, instruments, machinery and materials.
Best for: buyers who also want to see the equipment, materials and technical side of the industry.
The Hong Kong International Optical Fair is organized by the Hong Kong Trade Development Council. The 34th edition was scheduled for 4–6 November 2026 at the Hong Kong Convention and Exhibition Centre. Zones include lenses and frames, kids and reading glasses, sports and professional eyewear, smart eyewear and optometric equipment, and the fair runs an online matching platform alongside the show. International brands also exhibit, so it is a mix of Chinese and overseas companies.
Best for: buyers who want an international, design-oriented fair with both Chinese and overseas exhibitors.

Large international fairs, such as MIDO in Milan, SILMO in Paris and Vision Expo in the United States, attract exhibitors from many countries, and some Chinese suppliers take part. They can be convenient if you are already traveling to those cities, but they are not the most direct way to meet a wide range of Chinese factories. For a buyer whose goal is to source in China, the fairs held in China usually give a broader choice of suppliers and make factory visits easier to combine.
• Pick targets before you go. Review the exhibitor list in advance and mark the companies whose products match your needs. Do not try to see everything.
• Prepare a clear brief. Bring a short brief with the materials, styles, target markets and estimated quantities you are looking for, so that conversations are specific.
• Ask who really makes it. Ask whether the exhibitor is the manufacturer or a trading company, and where the frames are made.
• Handle the product. Open and close temples, check hinge feel, edge polishing, color and lens fit on the sample frames.
• Ask about terms. Ask what affects the minimum order for the styles you like, and how samples are arranged.
• Take notes. Collect business cards and take notes on every conversation, because details blur after a few days.
• Follow up in writing. After the fair, confirm what was discussed in writing, and request samples before any order.
• Plan to verify. If a supplier looks promising, arrange a factory visit or a video tour to see the production for yourself.
Social media will not replace a fair, but it is a useful way to find and cross-check suppliers. For buyers outside China, the platforms that matter most are the global ones:
• LinkedIn. Search company pages and employee profiles to see who works there, how long the company has existed and what it says about its products. A real company usually has a consistent profile across several places.
• Instagram and Facebook. Photos and short videos can show the product range, finishing and behind-the-scenes production. Look for original photos rather than images that appear on many other sites.
• YouTube. Factory videos help you check production steps, workshops and equipment, which are harder to fake than a profile page.
Chinese platforms such as WeChat, Douyin and Xiaohongshu are important inside China, but they are mainly in Chinese and used by domestic customers. WeChat is commonly used for messaging with Chinese suppliers once contact is made, but it is not the best starting point for most overseas buyers.
One practical point: Facebook, Instagram and X are generally not directly accessible from mainland China, so a supplier's presence on them may be handled by an overseas-facing team. That is not a problem in itself, but it means a polished social account says more about marketing than about production. Treat social media as a way to find and shortlist, and verify capability by samples and a factory check.
Search engines remain the most common starting point. Searching for the type of frame you need together with the production city, or for a supplier's name, usually leads to company websites and listings. Look at whether the website has detailed product information, real contact details and consistent claims.
B2B marketplaces such as Alibaba.com, Made-in-China.com and Global Sources let buyers search many suppliers and send inquiries. They are convenient for building a long list. Some points to keep in mind:
• Understand the labels. Read what a verification badge or membership level actually covers, because it may reflect a paid service rather than a check of factory capability.
• Compare, do not rely on one listing. Compare several suppliers and check whether the descriptions are specific and consistent.
• Confirm in writing. Move important details out of the platform chat and into written confirmations.
Channel | Strengths | Limits | Best use |
Trade shows | Many suppliers at once, direct talks, samples in hand | Travel and time, a good booth is not proof | Building a shortlist and meeting decision makers |
Social media | Free, shows the product range and company activity | Marketing-led, access limits in mainland China | Finding and cross-checking suppliers |
Search engines | Wide reach, easy to start | Quality of results varies | Initial research |
B2B platforms | Large supplier pool, easy inquiries | Listings vary in accuracy, labels may be paid | Creating a long list to narrow down |
Once you have a shortlist, the same steps apply, regardless of where you found each supplier:
• Identity. Confirm whether the company is a factory, a trading company or both, and check that the business name matches across its website, profiles and documents.
• Production. Ask for a video tour of production, or arrange a visit or a third-party inspection when the order justifies it.
• Samples. Order samples of the exact styles you plan to buy and test finishing, hinges and fit.
• Terms. Ask what the minimum order depends on, such as model, color, material and branding, and get terms in writing.
• Communication. Check how quickly and clearly the supplier replies and whether answers stay consistent.
• Trial order. Start with a small trial order before scaling up.
• At fairs: A booth with products that no one can describe in detail, an exhibitor who cannot say where frames are made, or pressure to pay before samples.
• On social media: Stock photos, an account with little history, or claims that change between profiles.
• On B2B platforms: Listings with generic descriptions, prices that seem unrealistic for the material, or a supplier that avoids a video call.
None of these proves a problem on its own, but several together are a reason to slow down.
