Every time I see someone put on cheap reading glasses that they purchased off a rack in some store, I think “why would you wear those?  down on your nose?  cheap lenses. poor quality lenses.  self prescribed reading power.  It’s a bad idea, people.  bad for your eyes, bad for your look, and just not cool.  Hey, generic means not specific to your needs.  Bargain eyeglasses come at a high price. Headaches, eye strain, blurry vision, and masking of other problems.  Don’t buy them, just don’t.  Book an eye exam.  Get the lenses specific to your eyes.  You only have one pair of eyes and they have to last you a lifetime.  They don’t look good either, unless you like adding 10 years to your look.
