/----/ Back before I had eye surgery and no longer need glasses, my opthomologist said don't buy the drugstore reading glasses because each of your eyes has a different focal level. You need prescription glasses. Single focus are cheap enough, and you can get a plastic coating to prevent scratches.I break, or mar the lenses, on my drugstore reading glasses often, so I thought I'd take a chance and buy the cheap, multi-pack readers that Amazon offers. I was delighted with my purchase as the glasses are exactly the same as the one's I've been buying at Walgreen's.
Walgreen's price: $20.00/pr.
Amazon's price: $3.00/pr. 5-pack.
Of course they are all imported.
Hope this helps someone.
