• Description

The blue light components of the visible spectrum can cause glare because it is precisely this light component that is strongly scattered at the blurring of the cornea, the eye lens and the vitreous body.

This short-wave, energy-rich component of the visible spectrum, which leads to substantial scattering and reduced visual performance and contrast, can be absorbed by cut-off filters. These special filters completely absorb short-wave blue and violet light.

450 nm Yellow: brightening and high contrast in half light
511 nm Orange 35%: high contrast in dim light and normal light
527 nm Orange 55%: high contrast in normal light
550 nm Orange 60%: high contrast in normal and bright light
Amethyst: increases the contrast of the front and back sight, intensifies the black colour of the target
