Not good.
Had glasses for about sixteen years now, since I was, I think, 12. Maybe 13. Anyway, tried contacts for a year or two half a decade ago but I didn't really liked it much, I mean it's convenient to not having to wear glasses, but they really strained my eyes at the end of each day.
I need glasses for further away, everything beyond 1 to 1.5 meters becomes increasingly blurry. Don't know how the US system with "20/20" thing works, but in our scale I have -3.00 more or less. The left eye being noticably better than the right though; -2.00 on the left, -3.25 on the right. They get worse every time I get it checked, sadly, don't remember what I had when I first got my glasses but it was probably still in the -1's.
I blame gaming and tv. 
For reading though they're still great. I can read the tiniest letters perfectly clear. I would need to take off my glasses to see more clearly up close.
