I'm -6 and the risk of complications is what makes me think I'll probably never want to do any corrective procedure. I had been considering it for a while, but one time when I went in for a checkup, I happened to chat with another guy there who was seeing the doctor because his surgery was making him see halos. Apparently they usually go away eventually, but I decided I'd rather not find that out personally.
And I feel there's a kind of meditative calmness to the blurriness that I think I might miss. It's quite nice when I'm going to bed or waking up and everything is just a blur, no distractions to catch my eye because I can't see them! I'm probably doomed if I'm ever in an apocalypse and lose my glasses, though (see Twilight Zone "Time Enough at Last").
