Some evidence? Macular degeneration, cataracts, pterygium and skin cancer (basal cell carcinormas and ocular melanoma) all have very solid links to exposure to sunlight. Heck, you can even have photokeratitis (corneal sunburn) from exposure to sunlight mostly from spending too much time at the beach or skiing with all the reflected light from the sand/snow. The snow form is affectionately(?) referred to as snow blindness.

You can have these triggered by UV sources other than the sun. Check "arc eye" for photokeratitis triggered by improper use of eye protection when welding.
