STEALTH PHOTOCHROMIC.

Very high-range sunglass with outstanding technical characteristics. The frame is made of Grilamid? TR90 material: very light, safe, shock resistant and elastic (virtually unbreakable). The nose-pad in TPR hypoallergenic material has some special holes to let out sweat. Three sets of interchangeable lenses packed in a very nice shock-resistant case: smoke, red revo or blue iridium (depending on the model) and photochromic. These last lenses in particular (that we purchase from the United States of America manufactured in a ISO 9001 environment) are of clear colour (87% of light transmission) but in presence of sunlight (and therefore of UV-A and UV-B rays), they become grey coloured (21% of light transmission) depending on the intensity and on the acuteness of the same. It takes them only 8 seconds to go from clear to grey and 60 seconds to go from grey back to clear (short reaction time). Obviously these lenses, just like all Dolce Vita® and Power Race® lenses, 100% protect against UV-A (290-315nm.) and UV-B (315-380nm.) rays and of course comply to the strictest quality standards for lenses such as ANSI Z80.3 (in U.S.A.) and EN1836 (in Europe). Last ?little? detail is the fact that these very special lenses are 100% completely anti-fog and when we say 100% completely anti-fog we really mean it. Try indeed to breath even from a close distance to these lenses and you will see that nothing happens to them. Then do the same with most of other lenses that claim to be anti-fog. You will be surprised.
