I have worn glassed since I was 3, I have pretty bad vision (astigmatism/lazy eye), but with Glasses/Contact lenses I have normal vision. I have seen a consultant about laser surgery, they eventually admitted that at my ages, 43, I would still need glasses for reading pretty soon after surgery, certainly within 5 years, maybe for driving too. The real thing that swayed me was the all 4 staff wore glasses!
I guess if you are younger it may well be worth doing. I do find it easier to read with contact lenses than in glasses though. I haven't tried varifocals yet, but i reckon I am only a couple of years away.
