Sports specific sunglasses and lenses are now available that are targeted specifically to the requirements of the golfer, the cyclist, the athlete or the mountain climber.
Perhaps the most important aspect of effective sports sunglasses is the optical quality and visual enhancement of the lenses. Many lens colors that are particularly effective in certain situations (such as brown, green, grey, yellow, orange, etc.) are now available. Yellow enhancement is particularly desirable in tennis, where balls are usually yellow. Amber or rose lenses enhance the soft grays that mark shadows on a ski slope. These shadows indicate ridges or bumps in the surface.
There are also a variety of multipurpose sports sunglasses on the market. Changeable lens systems are now offered by many eyewear companies and offer the wearer options when it comes to usefulness for different sports and different conditions.
