A long time ago I found this:

It seems to work, although I can't talk about these kinds of things with some people I know, who can be sort of blockheads to me sometimes (I mean, I love them, but sometimes they come off a wee bit dense. That's probably just how they've been brought up though, in the cases where they have flashes of insight). If you have the common kinds of vision problems (myopia, hyperopia, astigmatism, presbyopia) give this a go, but whatever you do, don't get LASIK (that's the elective surgery from Hell) and use contacts minimally and judiciously if at all.
