ZEISS Skylet®

Selective absorption for higher contrast

Skylet® is a high quality dip coating for the plastic range of lenses from ZEISS. Skylet® sun protection lenses have been specially designed for situations in which greater protection is required from UV light and glare, and special demands are made on contrast at the same time.
As such sports as gliding, skiing, cycling or motorcycling are often performed in difficult light conditions, high contrast vision is of special importance, especially from the safety viewpoint.

Skylet® filters out annoying blue scatter

The Sunglass Lens with Special Transmission Properties

On the basis of recent scientific advances and numerous tests, the R&D department at ZEISS has specially developed Skylet® sunglass lenses to meet the requirements of extreme light conditions. The special feature of these lenses lies in their markedly reduced transmission for the short-wave portion of visible radiation. The result: even in diffuse light, Skylet® sunglass lenses provide outstanding contrast.

Compared to traditional sunglass lenses, Skylet® sunglass lenses display higher transmission in the region in which the eye is particularly sensitive (V λ = 555 nm). With the same level of light reduction as other lenses, Skylet® therefore appears to be subjectively brighter to the wearer, but provides the same protection against glare.

How does Scatter Influence Colour Vision?

Direct sunlight is always scattered, with the blue portion of light being subject to the greatest scatter. Our colour perception is influenced by this effect, as all colours contain a small portion of blue. This is why, for instance, we see the sky as blue.

Due to the blue portion, all chromatic zones are shifted towards blue. The closer the coordinates are to each other, the less contrast is seen. The result is glare and blurred outlines which are particularly annoying in extreme light conditions, e. g. in dazzling sunshine on water or in diffuse light on the ski-run.

Contrast Enhancement by Reducing the Blue Component of Light

Contrast-Enhancing Effect

The attenuation of the blue portion of the spectrum results in a marked enhancement in contrast, as the chromatic zones move away from blue and the distance separating them increases.

There is another reason why the attenuation of the blue region of the spectrum enhances contrast. Due to the relative myopia of the eye for short-wave radiation, blue light is bundled in front of the retina and superimposed on the other colours – vision becomes blurred.

Brightening Effect

Skylet® sunglass lenses reduce the blue portion to such an extent that the wearer enjoys clear vision.
The best way to experience the contrast-enhancing effect of Skylet® lenses is to wear them outdoors on a sunny day. A comparison with traditional sunglass lenses will also show the brightening effect.

¡NUEVO! Protección UV
desde cualquier ángulo.

Para ofrecer a sus pacientes una protección verdadera, ZEISS ha desarrollado un tratamiento antirreflejante adicional en la parte posterior de las lentes que reduce la luz indirecta que se refleja en el ojo y que complementa la protección que ofrece la tecnología UVProtect de ZEISS en todas las lentes de plástico transparente ,que bloquea los rayos UV que vienen de frente.

Más del 90 % de la radiación UV viene directamente de frente. No obstante, y en menor medida, vienen también de los laterales y por detrás. Como algunos rayos UV pueden verse reflejados en los ojos por la superficie posterior de las lentes, los tratamientos antirreflejantes de ZEISS están diseñados para tener baja reflectancia en el rango espectral UV.

Ahora, la protección UV en la superficie posterior de la lente está integrada como característica estándar en todos los tratamientos especializados DuraVision de ZEISS.
