I do get the after burn effect after being in the sun. Doesn't bother me so much (beyond not being able to see anything). And like you, I often have to stop when I walk into a building after being in bright sunlight.
As for sunglasses, because I wear glasses 99% of the time, most sunglasses just don't work for me (two pairs of glasses on at once kind of thing and the clip-ons don't fit my glasses right and I can't afford custom-made). I'm now at the point where I just won't wear them unless it's one of those white hot kinds of days. And when I have to due to iritis.
Many hugs,
