Did you know that
The blue light visible to human eye is produced by high frequencies (from 380nm to 450 nm) that are the most dangerous (HEV: highest energy visible). The Blue Block lens protects from a maximum of 50% of these frequencies (up to 420nm), if it blocked them totally it would not allow the vision of the blue color. Blue is a primary color and this would alter the color perception.
420 nm Blue Block Filter
The blue light could damages the back of the eye as much as the UV rays could damage the front; for this reason it’s imperative to shield the eyes from this kind of rays.
The lenses with Blue Block treatment can screen the eyes from blue and UV rays, improving contrast and visual comfort, as well as reducing glare and reƽections on the lens. This treatment is also available on prescription glasses.
