Edge and comfort filters

Edge filter glasses are special glasses that are fitted with an edge filter. An edge filter is an optical filter that blocks or reduces certain wavelengths of light. Edge filter glasses are often used for eye diseases such as cataracts or AMD to protect the eyes from harmful radiation.

There are different types of edge filter glasses that have been developed for different purposes. Customers have the opportunity to try out certain variants in shop first.

It is important to select the right type of edge filter goggles for the specific application and ensure that they provide the required protection.

Filter lenses and glare protection

Contrast vision decreases with increasing age. Glare problems occur in sunshine or diffuse light. The quality of vision suffers and objects are overlooked. Just think of driving at night.

Light protection lenses in different tint colours and degrees can help. There are also photochromic tints that automatically adapt to the light conditions. Medical filter lenses absorb certain colour components of the light. Edge filter lenses filter out short-wave colours as well as UV radiation. The stronger an edge filter is, the larger the filtered spectrum and the more reddish the lens. An additional "polarising filter" prevents reflections.

Edge filter lenses can be prescribed for eye diseases such as retinitis pigmentosa or cone dystrophy. The lenses can also improve the subjective visual impression in cases of age-related macular degeneration and diabetic retinopathy.
