For most sports, good vision is essential to improve performance.  Whether it be golf, snooker, tennis, football or shooting, improving the visibility of the target, pin or ball will improve the overall perfomance.  For some sports, like football or rugby, contact lenses will be preferable, but for many other sports the use of specific tints can greatly improve the visibility of the contours of the fairway or greens in golf, or the target in shooting, or the ball in tennis.  For water-based sports like sailing or surf-boarding, tints can be used to eliminate the glare from the water surface and protect the eyes from the harmful effects of reflected UV light.

Sunglasses for sports like running, cycling or cricket. These tough sunglasses will stand up to a lot of what may be thrown at them, and with glazeable inserts they can be used instead of ordinary prescription sunglasses to deliver top sporting perfomance.
