PRESCRIPTION MOUNTAIN SUNGLASSES
The mountain environment presents a special challenge to eye health and specialist mountain glasses or goggles are a vital necessity.UV radiation exposure increases by 10% for every 1000 metres of altitude and fresh snow acts as a mirror reflecting up to 80% of UV light.Under these conditions even short unprotected UV exposure times can lead to premature ageing,Cataract or even life threatening skin or eye cancer.Polycarbonate lens material,standard on all our mountaineering glasses,blocks 100% UV but in situations of extreme glare from snow reflected light,Cat 4 Glacier glasses and Alpine sunglasses with extra dark tints are a great asset for comfort.
Light cloud will still allow the penetration of 80% of the UV and high lying atmospheric haze can even increase UV exposure.Prescription mountaineering glasses are therefore an important requirement for spectacle wearers to allow suitable eye protection to be used at all times.
Many mountain glasses also feature inner gaskets to protect against wind and spindrift and in some cases these can be removed,making the climbing sunglasses suitable for use as everyday sun eyewear increasing their usefulness and versatility.
Impact protection is also a vital consideration and all our climbing eyewear models come with very high impact resistant safety lenses as standard.
Rock climbers 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!
