Description:
Edge filters allow light to pass through almost unfiltered up to a cut-off frequency, but absorb a large proportion of the light above the cut-off frequency (edge). This results in an increase in contrast and a reduction in glare.
The darkened upper edge means that the glasses fit close to the head, effectively preventing stray light from above from reaching the eye. This is further supported by the wide temples with integrated filters.
The disturbing short-wave components of the spectrum in particular are filtered out, while a high degree of light transmission is achieved at the same time. This makes edge filter spectacles particularly suitable for the visually impaired. The edge filter spectacles are suitable for wearing over prescription frames.
edge filter spectacles can be combined with polarizing lenses (e.g. for epilepsy).
