I determined long ago that contacts are just too much work.
I'm a night owl (one word or two?) by nature, so having one more thing to fumble with in the morning--especially when groggy--is one too many. I also like having as little as possible to do when I get ready for bed. Plus I'm rather fond of reading, so it's nice to be able to take off my glasses when I read (I'm nearsighted), then put them back on when I'm done. And with Memorial Day (and the opening of apartment pools nationwide) right around the corner, I'm thinking it's nice to be able to just take my glasses off at the pool rather than mess with contacts.
Contacts are great for people who feel self-conscious about wearing glasses, but considering how fashionable glasses have become (i.e. designer frames and all that rot), there's not much to be concerned about. Plus people assume you're smarter when you wear glasses. Weird, but true.
But hey, if contacts are your preference, then enjoy. There's a number of advantages to contacts over glasses. I'm just too fond of my glasses to make the switch.
Oh, but I should mention that I did wear contacts the day of my wedding so there wouldn't be any glare on the photos. That was one time I was very glad I had worn contacts before and was comfortable wearing them again.
