If you want to have a competitive advantage on the tennis court, you'll need to have sunglasses specially designed for tennis, such as the Bolle Sunglasses we carry with the Competivision Lens Technology. While we carry other brands of tennis sunglasses, Bolle has made it their focus to provide the best vision for tennis. So what should you look for? Well, in the Competivision Lens, all colors except for optic yellow are muted, so the ball will be far more visible than with regular lenses, and they're tough too! In fact, the Bolle Competivision Tennis Lens Technology is the first lens created specifically for Tennis Players. They work so well that they received Tennis Week magazine's award for best on-court product and earned the right to be the official eyewear of the US Professional Tennis Association.
