I didn't start wearing glasses until I was 22 or 23 years old. I was sitting in the back of the class in law school, and I had to squint like mad to read the chalk board. I wore a combination of glasses and contacts for 10 or 12 years until I decided to get Lasik eye surgery. That was definitely money well spent.
I did some research, and it doesn't sound like there is a great surgical option for presbyopia, so I guess I'll use glasses for reading and computer use. The good news is that I can function without the glasses so long as I don't have to read really fine print.
