Description:
Edge filters allow light to pass through almost unfiltered up to a cut-off frequency, but absorb a large part of the light from the cut-off frequency (edge). This increases the contrast and reduces glare.
Thanks to the darkened upper edge, the glasses lie close to the head and effectively prevent stray light from reaching the eye from above. This is also supported by the broad brackets with integrated filters.
The disturbing short-wave parts of the spectrum in particular are filtered out, with a high degree of light transmission being achieved at the same time. As a result, the edge filter glasses are especially suitable for the visually impaired. The edge filter glasses are suitable for wearing over the correction frame.
Edge filter glasses can be combined with polarizing lenses (e.g. for epilepsy).
