It all depends on whether you feel the need for them. I started having troubling seeing to write checks to pay the household bills. That was when I was 38.

Then I was taking my glasses off to write checks. I had to hold magazines at arms' length to read articles. Enough. A few months before my 42nd birthday, I went to my eye doc. She is the best. I told her I needed bifocals, she tested me, and said I needed only a mild correction. I went to LensCrafters, got fitted, which is a tricky process since they must measure your focal depth and stuff, and got my new glasses with Progressive and Featherweight lenses.

I adapted almost intantly because I was ready for them and I knew I needed them. I just had to get used to turning my entire head rather than shifting my eyes, on occassion, to be able to focus.
