1. Anti-blue light lens

Anti-blue lens is a kind of digital protective lens that can effectively block high-energy harmful blue light, retain beneficial blue light, and reduce blue light's damage to the eyes. It is suitable for wearing when using LED digital display devices such as TVs, computers, PADs, and mobile phones.

2. Sunglass lenses

Sunglasses use metal powder to selectively absorb some of the wavelengths that make up the sun's rays, blocking uncomfortable glare.

3. Polarized lenses

When the sun shines on water, roads, snow and other places, messy light will be reflected. In order to filter these dazzling light, a vertical special coating is added to the lens, which is called a polarized lens. It can effectively suppress the glare even when looking directly at it. The sun is not easy to dazzle the eyes, it is most suitable for outdoor sports (for example: driving, skiing or fishing).

4. Smart color-changing lens

Also called "photosensitive lens", it is generally achieved by adding silver halide substance to the lens itself or spin-coating a color-changing film on the surface of the lens. The lens becomes darker under strong light, and becomes transparent under indoor light, depending on the intensity of light/ultraviolet rays. Weak automatic adjustment of lens color, one lens for dual purposes, automatic blocking of ultraviolet rays.

5. Sports lenses

Safety protection lenses worn during sports pay attention to safety and protection performance. This kind of lens generally refers to the KR super-tough lens in the PC lens or the resin lens, which has high-strength toughness, strong impact resistance, not fragile, and safer.
