ASpie Eyes.

As long as I can remember, I've been sensitive to bright lights. And some fluorescent lights. I've been wearing sunglasses since I was old enough to get some for myself. Were it not for the "public image" thing, I would often wear them indoors as well. But, as they say in show biz- you're always on stage (something that a lot of newcomers in the business would do well to remember). Sometimes I think the image can be a little flexible, and I keep my shades on when I'm inside. (I guess some people expect that sort of thing from a musician anyway.) I don't need to do that at home, because we keep the light-level lower than most people. 60 watts instead of 100 - that sort of thing.
And fluorescents. Geez. Some places I just cannot be in for more than a few minutes, or I get a headache. And twitchy. And just generally claustrophobic - and that can happen even in large indoor spaces. Just must get out of there!
I was convinced for many years - after searching for a possible cause - that these reactions wer a result of smokey "smudgepot" fires at camp when I was in Scouts. We made outdoor fires with lots of smoke to keep the mosquitoes at bay. Well, it kept the bugs away somewhat, but it made the eyes smart, too, along with the mosquitoes. I always thought those fires were the cause, even though the connection was unproven.
Hah! Now I know better.
