These men's Oxigen-brand plastic-frame sunglasses mix elements of design that come from sports shades and the sunglasses we wear during our daily lives. They have a thick plastic frame, which creates the impression that they are durable. Everyone who wears sunglasses on a regular basis needs to have a pair of shades that will be with them over the long haul. The way you take care of your sunglasses will determine how long they will last. When a pair of shades is made of more durable materials, you won't have to worry about them letting you down.
