This is my first time to buy prescription eyeglasses, so, I don’t have any relative experience of shopping glasses online, you know that nowadays, there are so many kinds of eyeglasses frames on the market, many types of eyeglasses are made up of high-tech materials like titanium, while lenses have become thinner and lighter. But I couldn’t get one less than $300, that’s much above my reach, my friends told me to try online site if I need cheap ones, some even less than $10, does cheap mean fake? How can I trust them?
