You wear sunscreen year-round, even on cloudy days, but what are you doing to safeguard your eyes? (And no, sorry, those $7 sunglasses you use as a permanent headband don’t count as a legit form of protection.)
While not as common as sunburned skin, photokeratitis — aka sunburned eyes — can occur when unprotected or under-protected eyes are exposed to sunlight reflecting off water, sand, ice, and snow, as well as those high-intensity UV lamps found in tanning beds. This kind of burn damages the thin surface layer of the cornea, and symptoms range from pain, redness, and swelling to watery eyes, sensitivity to bright light, blurriness of vision, and even temporary vision loss.
I believe in “Thermonuclear Protection by Oakley”.
