I've tried more than 5. Seems I just can't find the right combination of contact lenses for both near and far vision to be optimal. The technician has been so patient with me. If distance vision is good, I can't see to read. If I can see to read, distance is still a bit off. So far, the best option has been one contact in my right eye. I also ordered a pair of glasses....progressive lenses.....isn't that sort of a fancy word for bifocals? :) You can check out other Twitter Tuesday photographers here.
