I had ordered a pair and used it for about 2 months now. Unfortunately the quality is quite poor. One of the lenses is moving quite a lot while the other started ci crack by itself in 2 places, due to pressure put by the frame. Also the fit is quite bad allowing a lot of space on the cheeks. I do not recommend them.
