I need to order a pair of computer glasses when I am using computer. As my working needs watching computer all day long, my old prescription can’t protect my eyes anymore. My optical doctor recommends me to order a special prescription which is computer glasses in his hospital. But the price there is too expensive and he didn’t give me any discount. I just heard that the price of prescription online is cheaper than hospital and local store. so i want to know which store is best ? thank you for any help!
