JeanieG, after cataract surgery its necessary to wear dark glasses out in the sunlight to protect the eyes. And distances are fine, but close up requires glasses. Computer needs 1.5 lenses and reading requires 2.5 lenses. I have a plastic pair of each at the computer and night stand. I wear a pair with reading lenses in lower half that sits on the lower part of my nose...handy for my 'granny' advice for the 'younger' generation! And it took a while for the skin cancer surgery to heal up the blood vessels and nerves back to the eyes. If anyone needs cataract surgery, go for it, 'cause it really helps to see better immediately. Although I am not driving, I find having dh drive is not so bad after all. LOL!
