When it comes to sunglasses, you basically have two frame choices these days. You can choose sunglasses with metal frames. These are Aviators and other rectangular sunglasses. Of course, there are also angular sunglasses made with plastic frames. These are mostly Wayfarers and other oversized sunglasses which have prints or bright colors on their plastic frames. Most men prefer metal frames because for them, these look sleeker and more masculine. Undeniable, more feminine designs can be found on lines with plastic frames.
