Lens Catagory
Hello friend,
Nowadays, we have developed different type lens.
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. Sunglasses
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 paint is added to the lens, which is called a polarized lens, which 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 material to the lens itself or spin-coating a color-changing film on the surface of the lens. The lens becomes dark under strong light, and becomes transparent under indoor light. According to the intensity of light/ultraviolet rays Weak lens color can be adjusted automatically, one lens is dual purpose, and ultraviolet rays are automatically blocked.
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 and toughness, strong impact resistance, not fragile, and safer.
