The most sport specific technology ever invented, Bollé's patented Competivision™ is the only lens you'll ever need for tennis. Competivision lenses act like filters, carefully muting all colors in the spectrum except for optic yellow. The result: a tennis ball that pops outof the background. That's why the lenses are the offical eyewear of the US Professional Tennis Association. Available with a variety of styles, many of which feature interchangeable lenses for 100% UVA and UVB protection on and off the court. Matte Black TT Silver Crimson
