I started wearing glasses when I was about thirteen years old. I don't need them desperately. (Strangely enough, the first time I took my driver's license eye exam I failed without my glasses. When I went to get my license renewed, I passed.) However, I do wear them when I'm driving in unfamiliar cities or late at night, since they do improve my vision. I also sometimes wear them when watching TV.
I'd probably wear them more often if I could find a pair that really looked good on my face. I have a twofold problem: My face is very round (so round glasses only make it look rounder) and my nose is pretty much typical-Asian flat (so I have to have little nose-pieces to keep them up). On top of that, I tend to be rough on glasses, and wire frames are often too delicate for me. Believe me, finding plastic frames with nose-pieces can be difficult--and pricey.
I hate the expense of glasses. The last time I went for an exam plus two pairs, it cost me a whopping $500! That's ridiculous! However, I just discovered http://www.ZenniOptical.com, which sells prescription eyeglasses at a discount rate. In fact, they sell single lens glasses for just $8! The frames aren't designer, but they are solid and basic, which is the only thing I need.
So check out the $ 8 Zenni Optical Rx Eyeglasses if you're looking for a great bargain on glasses!
