I'm legally blind in my left eye, which the right eye pretty much used to make up for until I hit 40. I used reading glasses for years, then finally broke down and got bifocals last year. I hate glasses but don't want to put things in my eyes, so I put up with them and enjoy better vision. My eyes still get blurry when I'm tired or my blood sugar goes too high, and I think my meds have something to do with it as well. But overall, I'm doing OK with the bifocals.
