Yes, I wear glasses. I have 20/1400 vision without glasses, so yes, I'd say that they're necessary.
I've needed glasses since age 5; got them at age 6. I needed glasses because I read so much as a kid and watched TV a lot (special interest shows of mine). I think that the reason stereotypical geeks/Aspies have glasses is because of this very reason. We read a lot. When you read, you strain your eyes. You develop myopia. Plain and simple.
