Self-tinting lenses – (Sun)glasses for any kind of light
Glasses on. Glasses off. Glasses on. Glasses off. It’s pretty tiresome, and not just when you’re jogging, walking or shopping. optovision self-tinting lenses put an end to this continuous backwards and forwards between sunglasses and glasses. To do so, optovision ColorMatic lenses use cutting-edge technology by Rodenstock. And you notice it every time you change from inside to outside: the lenses react in a matter of seconds, crystal clear inside and turning into dark sunglasses outside.
Two glasses in one
Anyone who has ever tried out self-tinting glasses knows that not all self-tinting glasses are the same. Sometimes the transition takes too long, sometimes the lenses are too dark inside, then too light when outside again. optovision ColorMatic lenses are different: with these self-tinting lenses you genuinely own two glasses in one, irrespective of whether you fit your progressive glasses, single vision glasses or office glasses with self-tinting lenses. Inside the lenses are just as clear as with conventional glasses. Outside they are just as dark as sunglasses, naturally with full UVA- and UVB-protection. With ColorMatic you have a pair of glasses that suits any light.
Good to know: how self-tinting lenses work
Self-tinting (photochromic) lenses contain special molecules that react to UV light. If too much light falls on the lens, the molecules open up like miniature parasols. The lenses become darker and protect your eyes. If the UV light is reduced, the molecules close again, to a greater or lesser extent, depending on the light intensity. With conventional self-tinting lenses each molecule reacts differently. The result: different colours when lightening or darkening. Not so with ColorMatic lenses. They have uniformly coloured and – even after some years – colour-fast molecules, for a constant tone. These molecules are also bigger and respond more sensitively to UV light, including in the shade and in any season.
