I have 20/20 vision. I can read an eye chart all the way to the last line. A couple of years ago my opthamologist told me that by the age of 42 I would need readers. Bingo. I just broke down and bought a pair. Actually 3 pairs. The lowest they had was +1.50. They give me a headache but at least I can read tiny print on pill bottles and such. I still don't need them for actual reading. I can still read books, magazines and newpapers ok. But I don't think that will last much longer. I hate getting old!
