Saturday night I was reading and I didn't bother to get up and get my glasses, therefore I end up with on of those headachs right between the eyes when I went to bed. I wear glass b/c of a stygtism (not sure on the spelling). but distance is a challegen when driving. My glasses also are my sun glasses, the price of one set in one pair. the only thing that is annyoing is that I have to carrie them when I am driving or need sun-glasses oh and night driving.
