Amber blocks blue light to heighten contrast sensitivity and visual acuity and is recommended for baseball, softball, football (daytime), skiing, and water sports. This lens helps reduce glare during competitive sporting events without having to wear bulky—sometimes loose-fitting—sunglasses. Baseball players benefit most from the Amber lenses because it blocks out blue light which causes “visual noise” while the red colors, such as a baseball’s seams, are accentuated. Both Mark McGwire and Chipper Jones have worn these lenses.
