Specialist prescription and non-prescription sunglasses with high impact resistance and UV protection
High level mountaineers have similar requirements to skiers and snowboarders of course and UV hazards of snow blindness are well understood. Wind and spindrift are also issues.
Rock climbers however often use their conventional everyday glasses but many rock types (especially limestone) reflect large amounts of UV. In leader fall situations, frame fit and impact resistance can be important. So for those sun kissed Mediterranean sport climbing trips it’s great to have a separate pair of SPEX FOR THE ROCK.
Looks cool in the bar too!
