A few months before I turned 40, the optometrist said that I "could wear bifocals very nicely" and when I said I wasn't 40 yet, she said that was right around the corner! I have had progressive lenses since I was 40 and like them. As an organist/pianist, I now have the mid-vision glasses also-AKA organ glasses. At least I don't look like I will tip over backwards trying to read the music!! They also work very nicely for painting my toenails, using my sewing machine and cutting my husband's hair.
