The gray-green lenses allow golfers to better differentiate distance on a golf course. Golfer Justin Leonard has commented that with the gray-green lenses he is able to separate out every blade of grass. Baseball players benefit most from the amber lenses because amber blocks out blue light which is called "visual noise" by vision experts while the red colors, such as a baseball's seams, are accentuated.

This lens helps reduce glare during competitive sporting events, such as baseball and golf without having to wear bulky, sometimes loose fitting sunglasses.
