Wearing sunglasses when out and about not only blocks out glaring sunlight, but more importantly, this habit also helps prevent a range of eye conditions. What harm can UV rays cause to the eyes? And how should different groups of people choose the right lenses for themselves? Let's find out.

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.” 

When choosing color-changing glasses, you should mainly think about the lens features, how you plan to use them, and your color preferences. Photochromic lenses can also come in multiple colors, such as gray or brown.

If you’re in the eyewear business, the Wenzhou International Eyewear Exhibition, taking place from May 8 to 10, 2026, is well worth a visit. This event brings together over 700 supply chain manufacturers—from smart manufacturing to spot purchasing—and attracts industry insiders. As a lens supplier, we don’t just want to tell you “what we can produce”; we’d also like to discuss how we can help you solve the challenges you face with your orders.

Many people start experiencing presbyopia (age-related farsightedness) after age 40. Seeing far is clear, but reading up close becomes a struggle. Hearing that progressive lenses can handle distance, intermediate, and near vision all in one pair—eliminating the hassle of switching glasses—is incredibly tempting.

When buying glasses, many people are drawn to the "2-in-1" convenience of photochromic lenses. However, a crucial fact is often overlooked: the optical performance of photochromic lenses has a definitive lifespan.

As spring warms up and Shanghai extends its invitation, an industry gala dedicated to the optical world arrives as promised.

As the weather gets warmer, more and more customers are choosing photochromic glasses. But do you know how to choose the right photochromic lenses?

The principle behind photochromic lenses is “photochromism.” Photochromic lenses darken outdoors, similar to sunglasses; they return to colorless and transparent indoors. Photochromic lenses are divided into two types: base photochromic lenses and coating photochromic lenses.

Throughout the development of the human visual system, from birth to old age, the structure and function of the eyes undergo significant changes, with different age groups facing distinct visual challenges. Research indicates that scientifically informed eyeglass usage strategies can effectively protect vision, prevent myopia progression, and enhance quality of life.
