Polarising sunglass lenses

Comfortable vision without irritating reflections.

What do polarising sunglass lenses do?

These are a must-have for skiers and water sports enthusiasts, but they also help almost any spectacle wearer enjoy better vision: sunglass lenses with a polarisation filter. The special coating reduces irritating reflected light, i.e. when sunlight hits a wet road, snow, water or metallic surfaces. At the same time, a special tint improves contrast and colour perception.

The result: fewer irritating reflections on the lens, giving you especially clear, comfortable vision – even in bright sunlight. This useful extra is great not only if your eyes are sensitive to glare, but also for driving, spending time on the beach, playing sports or performing other daily activities – polarising sunglass lenses ensure significantly increased visual comfort. And of course sunglass lenses with a ZEISS polarisation filter offer 100% protection against UVA and UVB radiation.

Here's how polarisation works.

Natural light travels in all directions. It is therefore classified as unpolarised. When light beams come into contact with a reflective surface, e.g. sunlight hitting water, snow, a wet road or a spectacle lens, it is reflected back and diverted in a particular direction. In other words, it's polarised.

The majority of this light is horizontally polarised, i.e. it is arranged horizontally. However, a polarisation filter in the spectacle lens is aligned vertically and thus blocks the reflected light, nearly completely eliminating reflections off the water, wet roads or snow.
