Polarized lenses – better vision

Versatile lenses for sunglasses, driving and many other uses

Skiers, pilots and water sports enthusiasts are sold on them. However, these lenses are also excellent solutions for virtually anyone who wears glasses: lenses with polarizing effects.

These special lenses prevent light reflections and mirror images created by the sun’s rays as it hits wet pavement, water or metal surfaces, for example. As a result, they protect wearers from eye fatigue because the eyes no longer have to adjust to constantly changing light conditions. People who wear these lenses tend to be a lot more relaxed and feel better about wearing glasses.

How does the polarization principle work?

Natural light is unpolarized light that vibrates in all directions. However, whenever a ray of light hits a smooth surface, e.g., when the sun encounters a wet road, the light is partially reflected by the water and guided in one direction. In other words, it is polarized.

The reflection creates an unpleasant blinding effect (glare) because of the polarized light – a safety risk not encountered by those who wear lenses with polarization filters. The polarization filter is installed horizontally and does not allow the reflected, vertically directed light to penetrate it. Consequently, the sometimes hazardous reflections produced by water surfaces and wet streets are almost completely eliminated. Polarized lenses offer an additional bonus: 100% UV protection!

Polarizing lenses keep you safer, but they also offer some important visual benefits: thanks to the special coloring of the glass, they deliver substantially improved contrast vision and more brilliant colors. Speaking of colors, polarizing lenses by ZEISS are available in either gray or brown tints.
