WOF: More Than Just Lenses

China Wenzhou Int'l Optics Fair 2026 is in full swing. On the morning of the first day, both old clients and new friends kept coming by to talk with us. To be honest, after all these years in the lens business, what makes us feel most at ease is that the customers we meet are getting more and more "professional."

The questions they ask are very specific: What's the light transmittance? How do you control the edge thickness of high-diopter tinted lenses? Can you support small-batch custom colors? When they bring up these kinds of real-world questions, we know they truly understand what they need.

Our technical team members have barely sat down these past two days. They've been at the booth with color sample books, going over shades, explaining the process, and calculating specs with each customer. One customer who runs an outdoor sports eyewear brand brought over a few new frame designs of his own. Together we explored what tint depth and base color would work best for different scenarios like cycling, skiing, and fishing. After half an hour of discussion, both sides were really excited. That feeling of "ask and answer on the spot, work out the solution together" is exactly the kind of value that offline trade shows bring—something you just can't replace online.

Tinted Lenses: More Than Just Adding Color

When many people hear "tinted lenses," their first thought is, "Oh, like sunglasses." And it's true—the most common use of tinted lenses is in sunglasses and protective eyewear. But honestly, even among tinted lenses, the quality and technology can vary a lot.

The lenses we're highlighting this time aren't just about how they look—though color matters too. What really sets them apart is optical uniformity and added features.

Here's a simple breakdown: With basic tinted lenses, if the manufacturing process isn't advanced enough, the color can end up uneven. This is especially noticeable in high-prescription lenses or large lens blanks, where the center and edges may look visibly different. We've made multiple improvements to our tinting process. Whether it's a gradient tint or a solid single color, we achieve smooth light transmission and a clean, clear look.

Also, what the market wants from tinted lenses has changed in the last couple of years. Before, people mostly cared about style—"as long as it looks good." Now, customers ask for UV protection, blue light filtering, and even polarized options. In simple terms, people want one lens that solves multiple problems.

That's exactly where we've been focusing our efforts. Today, our tinted lenses can come with a range of functional coatings. Without affecting the color appearance, we can add UV400, blue light blocking, and even polarization. At a recent trade show, several high-end outdoor brand customers were especially interested in this combination.

The Basics of Prescription Lenses

Now that we've talked about tinted lenses, let's get back to what we do best—prescription lenses. If tinted lenses are like the "extra credit," then prescription lenses are our "bread and butter."

We've always focused on making mid-to-high-index prescription lenses. The 1.60, 1.67, and 1.74 options are our best-selling series. Why? Because more and more people need stronger prescriptions these days. Between long hours staring at screens and spending less time outdoors, customers expect more from their lenses than just "seeing clearly."

At a recent trade show, a eyewear chain owner from Jiangsu told us about a common trend: when customers walk into a store, they often ask directly for the thinnest lenses, blue light protection, and a coating that resists dust. Behind these requests is a real test of a lens manufacturer's basic optical skills and coating technology.

On our booth, we set up a side-by-side comparison: two 600-degree lenses—one with a 1.50 index and the other with a 1.74 index. The difference in thickness was obvious to the naked eye. Many buyers picked them up and compared them themselves. After seeing that, they didn't need much explanation—they already knew which one worked better.

Our coating technology also got a lot of attention at the show. Many returning customers know that we upgraded our coating line a few years ago. Now our coatings are more consistent when it comes to scratch resistance and oil-and-water repellence. In simple terms: they don't scratch easily, and they don't attract fingerprints or dust. When it comes to selling lenses in a store, these small details are exactly what customers notice as "quality."

To friends who couldn't make it

As I write this news update, the WOF is still going on. If you happen to be in Wenzhou or can still get here in time, you are very welcome to stop by our Aifanda booth.

If you can't make it this time, our sales and technical teams are always available online. You can reach us through our website or contact us directly. Either way, you can still get color samples and lens samples. And if you have any questions about tinted lenses or prescription lenses, feel free to reach out anytime.

Making lenses—on the small side, it's just a piece of resin; but on the bigger side, it's about everyone's daily "visual experience." We won't claim we do everything perfectly, but there is one thing we've always stuck with: we don't treat our customers like beginners, and we don't act like we're the only experts. We say what we mean. If we can do it, we will; if we can't, we'll honestly tell you, "We're still figuring this one out."

I think that's the main attitude we wanted to share at the China Wenzhou Int'l Optics Fair.
