I needed glasses to correct a wondering eye as a kid, got the wondering eye from taking a header down some stairs, dropped those in grade 8, and survived nicely without any glasses, until I turned 40, then about a week later my arms shrank until they were too short, and I needed readers. When I was 45, I found things like street signs hard to see, after dark, now at 50 I need one pair of glasses for seeing and another pair for reading, so I think bifocals are in my future. It pretty much means going to an optometrist and getting real glasses <sigh>
