>it took me a long time before I realized I needed glasses.

I'm rather astonished how relatively poor my eyesight had become before even thinking I might need glasses. Boil the frog, I suppose.

Yep. And it's not as if I needed the hint, most of my family wears glasses. It's just that it changes ever so slowly day-by-day and then one day you wake up with a headache so bad that you can't see at all. Getting reading glasses was a major improvement in quality of life.
