Spektrum Östra Bio Black line

Östra Bio Black Line is developed for bright days on high alpine glaciers. A Dark Smoke lens from Carl Zeiss protects you from harmful radiation as well as glare from ice and snow, all with a matching midnight black frame and band. Uncompromisingly built in plant-based materials for the glacier but just as functional on brilliant winter days when your eyes need extra protection. The extra lens from Zeiss with Sonar technology gives you extra good contrast in poor light conditions and allows you to tackle whatever weather the mountain has to offer.
