I remember being sensitive to sunlight when I was in high school but I thought it was my contact lenses. It wasn't much of a problem before. My mom's house has this wonderful dark pine heartwood paneling in the livingroom and giant oak trees that shade the windows so the house is always cool and dark. When my husband was alive, he actually prefered the house darker than I did. At home, I keep the walls painted fairly dark and the lighting indirect as much as possible. At work my new office space is in an area with a lot of flourescent lights, but they're so high up its almost like indirect lighting. Recently, though, I've started having to keep sunglasses handy even on overcast days. Most of my professors keep the classrooms dim for the sake of the projectors - death by PowerPoint - but one kept the lights on yesterday while we were filling in a review sheet for the next exam and I thought I'd never get through the class. I had to keep my hand shielding my eyes all through it.
Oh, gods, I'm rambling again. Sorry.
