UV and Sun Protection for Your Eyes: Sunglasses and Beyond
Ultraviolet radiation from the sun is a major risk factor for cataracts, pterygium, macular degeneration, and photokeratitis (arc eye). Proper UV protection — through certified sunglasses, hats, and UV-blocking contact lenses — is one of the most important long-term investments in eye health.
Overview
UV and Sun Protection for Your Eyes: Sunglasses and Beyond
Uses & Indications
Photokeratitis: painful sandy eyes, tearing, photophobia hours after UV exposure
Pterygium growth across cornea from cumulative UV (surfer's eye)
Accelerated cataract development from UV-B exposure
Macular damage from chronic UV and blue light exposure
Eyelid skin cancers on UV-exposed eyelid margins
Pinguecula: yellow raised deposits on conjunctiva from UV and wind
How to Use
UV-A (320-400nm) penetrates deep into the eye, reaching the retina
UV-B (290-320nm) damages the cornea and lens (keratitis, cataracts)
Reflected UV from snow reflects up to 80% of UV radiation
Water, sand, and concrete also reflect significant UV
Cloud cover does not fully block UV — 80% penetrates thin cloud
High altitude increases UV exposure by approximately 10% per 1000m
Benefits & Effectiveness
Wear CE-certified UV-400 sunglasses that block 99-100% of UV-A and UV-B
Choose wraparound frames for peripheral UV protection
Wide-brimmed hats reduce UV reaching eyes by up to 50%
UV-blocking contact lenses for additional corneal protection
Avoid peak UV hours (10am-4pm) when sun is directly overhead
Protect children's eyes from an early age — UV damage accumulates over life
After snow activities or water sports: watch for photokeratitis symptoms
