Negative Positive
Title: This is glasses, not sunglasses.
Review: I bought it for my father as a gift. At first time, my father liked it too much because design of these glasses, but after 1 week, my father can not wear it any more, because they made his eyes hurt. Then I tried, and the same result.I really like design of glasses, but it's useless if you use as sun-glasses.
