Contrast enhanced and glarefree Especially in dark or very bright environments, but also under fast changing light conditions contrast enhancing glarefree lenses have a great advantage: Even under extreme conditions objects are clearly more visible. Color lenses can also be contrast enhancing, e.g. organic lenses enhance green contrast – a special effect in wooded areas. By using our Colortester you can test which lens color affects which environment. In Sun & Fun sunglasses by optovision the blueblocker filters the disturbing blue portion of sunlight and ensures extremely contrast rich vision. Especially for drivers, optovision developed a lens which changes its color according to the light conditions, even through the windshield; this always guarantees optimum vision. Orgalit DriveWear lenses also enhance red and green light for better recognition of traffic signals. All dark tinted lenses provide glare protection. Furthermore, polarizing lenses specifically reduce glare from sun reflections, e.g. on wet roads, water surfaces or snow. DriveWear lenses are also fitted with such a polarization filter.
