Östra Bio Black Line Black

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