According to the shape of glasses frames, they can be divided into: full frame glasses, semi rimless glasses and rimless glasses. As for the materials, they can be divided into: Metal, Plastic, Titanium, Memory metal and Memory plastic. Titanium,Memory metal,Memory plastic are bendable which are very convenient to adjust according to your own favor. Personally speaking, rectangular big glasses are quite popular and aviator glasses are also a nice choice. When you choose frames, you may pay attention to the following points: first, select an eyeglass frame that is wide enough for your face, but not so wide that it fits too loosely; second, choose a color for your frame that compliments your face and masks the strength of your prescription; last, select a pair of frames that you like.
