These Oxigen double-bridge men's sports glasses have lenses with a variety of tints throughout all the varieties available. There's a small piece of metal at the top of the lenses that allows for the manufacturer to add some color to the glasses. The color that's present blends in with the dark color of the lenses. You will find that it's better to have sunglasses that come in subtle shades than sunglasses that are bright and colorful. Flamboyant sunglasses are more difficult to match with a lot of outfits in a wardrobe.
