These Oxigen semi-rimless color-mirror-lens men's plastic glasses are a cross between aviator shades and the sunglasses you see athletes wear on a regular basis. In the past, athletes had to settle for sunglasses that, although blocked UV rays, did nothing for them if they had any sort of fashion sense. These sunglasses come in black, brown and white frames with different color lenses. The white frames are especially perfect for anyone who wants to get involved in winter sports. The type of sunglasses you wear will affect your ability to work out when the sun remains high in the sky.
