Blue light is a part of visible light in the 380-500nm range. It can lead to unwanted degradation processes inside the eye.

It's especially important in case of VR headsets, as your eyes are extremely close to the display.

How it works?

BLP allows the lens to reflect excess blue light, protecting your eyes.

Lenses with BLP are more resistant to water, oils and static charge. Thanks to these features they're much easier to keep clean.
