China Blue Light Blocker Lens Manufacturer and Supplier

Blue Light Blocker Lens

Short Description:

The blue blocker lens is a virtually clear lens that blocks HEV blue light and provides maximum UV protection with minimal color distortion. It is made with a blue-light-blocking polymer that is directly incorporated into the lens material. This polymer absorbs the blue light, preventing it from passing through the lens to your eye. Because it is a clear lens, Blue blockers can be used with everyday glasses instead of a regular optical lens for all-day protection from blue light and UV exposure.

How Blue Light Blocking Glasses Work

Material Absorption: Anti-blue light factor is added in the lens base material to absorb harmful blue light in the life.
Coating Reflection: These lenses block a percentage of blue light with a special coating that reflects some of the blue light away from your eyes.
Material Absorption + Coating Reflection: With dual technology, namely, the adoption of coating on the surface of lens and adding anti-blue light factor in the base material of lens, these lenses can provide you with double-effect protection, and you don’t need to worry about that the coating film of the lens will fall off in the process of long-term use or the effect of blue light protection will be reduced by scratching.
Blue light lenses have a yellow tint, while others look clear. Typically, lenses that look more yellowed tend to filter more blue light than their clearer counterparts.
