Zurich Original Silver SG-1

Zurich Original Silber - Medium density

It is worrying that due to the increasing damage to the ozone layer and the resulting increase in UV radiation, more and more cases of eye diseases (mostly cataracts) are being registered.
It is also alarming that some sunglasses even promote eye damage due to sun exposure because the pupils of the eyes open wider behind a dark lens, allowing more UV-A rays to enter the eyes.
 
ZURICH SUNGLASSES FIT OVER MOST VISION CORRECTING GLASSES

The medium density is for general “all purpose” use for those that are moderately active outdoors, and can be used for driving, or flying in bright sunshine. They block most of the glare in sunny conditions, and can be useful on dull, gray, overcast, gloomy days as well.

ZURICH sunglasses block UV-A (98%), UV-B (100%) and IR (65%) rays and protect your eyes. Thanks to the strong tint (93%), you can fly close to the sun without being blinded.
ZURICH sunglasses are made of a high-quality polycarbonate of high optical quality. They are clearly different from the cheaper polarised glasses which only work on reflected rays (such as water reflections).
Optimum contrast is achieved in the sunglasses without changing the colour values (no yellowish tint).
ZURICH glasses offer a distortion-free field of vision over 180°. They are comfortable to wear and do not cause allergies (such as those caused by nickel). ZURICH glasses fit over most optical glasses.
