I'm wearing a pair of low-magnification (1.50?) Foster Grants now. I like them for the computer, as the focal length is a little longer than the 2.50's I use for reading. I'm under the impression that the lenses in the FG's are a little better quality than those in the Walmart glasses, which I also have.
Never wore reading glasses until I got cataract surgery this spring. I wore progressive bifocals for my near-sightedness, which I no longer have. 20-20 beyond 5 ft, but I can still make out the front sight.
