Which kind of vision problem do you have? I think you'd better have your eyesight checked by an eye doctor first. And tell him or her that you want to buy a pair of computer glasses. Then they can give you a prescription for you to order a pair of computer glasses. But when I have an eye exam in an optical store, the optician told me that she will make a pair of computer glasses for me if I show her my prescription next time.But I also can buy a pair of prescription glasses with the same prescription. So I don't know what's the difference between a prescription for computer glasses and a prescription for regular glasses. I don't know whether she is professional or not. but I just doubt about that. Anybody can tell me the difference about this?
