Your cornea absorbs almost all of it, which is why the damage shows up fast. A day on snow without protection can give you photokeratitis, which is sunburn of the cornea. It feels like grit in your eyes and usually arrives six to twelve hours after exposure, often in the middle of the night. Long term, UVB is associated with pterygium, a fleshy growth across the white of the eye that skiers and surfers get, and with skin cancer on the thin skin of the eyelids.\u003c\/p\u003e\u003cp style=\"margin:0 0 14px;font-size:15px;line-height:1.65;max-width:760px\"\u003e\u003cstrong\u003eWhy UVA matters.\u003c\/strong\u003e UVA is the longer wavelength and it does not stop at the cornea. It passes through to the lens inside your eye and on to the retina. You feel nothing at the time, which is the problem. The damage accumulates over decades and is linked to cataracts and to age related macular degeneration. UVA is also present all day, all year, and it passes through cloud, so overcast days are not safe days.\u003c\/p\u003e\u003cp style=\"margin:0 0 14px;font-size:15px;line-height:1.65;max-width:760px\"\u003e\u003cstrong\u003eWhy it matters more on snow and at altitude.\u003c\/strong\u003e Fresh snow reflects up to 80% of UV straight back at your face, so you take it from above and below. UV intensity also climbs roughly 10% for every 1,000 feet you gain. A bluebird day at 10,000 feet on snow is one of the harshest UV environments most people ever stand in.\u003c\/p\u003e\u003cp style=\"margin:0 0 14px;font-size:15px;line-height:1.65;max-width:760px\"\u003e\u003cstrong\u003eOne more thing worth knowing.\u003c\/strong\u003e A dark lens with no UV protection is worse for your eyes than no sunglasses at all. The tint makes your pupils open wider, so more UV gets in. That is why the lab number matters and the tint does not tell you anything on its own.\u003c\/p\u003e\u003ch4 style=\"margin:22px 0 10px;font-size:15px;\"\u003eWhat these standards mean\u003c\/h4\u003e\u003cp style=\"margin:0 0 14px;font-size:15px;line-height:1.65;max-width:760px\"\u003e\u003cstrong\u003eANSI Z80.3:2018.\u003c\/strong\u003e The United States standard for non prescription sunglasses.
