I have worn glasses for nearly 40 years. 17 years ago I scratched my cornea and had to have some surgery. They told me then that I was not a good candidate for contacts. I have one near sided eye, and one far sided eye. (just like my mom) Can't seem to get the no line bifocals, middle part perfect for the computer work even though they have rechecked the prescription. The Dr says that my corneas look good and that I can try a contact in one eye and then just get readers with just one eye prescription. Don't know if it is worth the hassle of all that. Guess I'm stuck with glasses.
