How Lenses Contribute To Reaction Time With Different Colors

Sports. It’s a profession, an outlet for stress, an opportunity for weekend warriors to let loose their Herculean strength and endurance, and a major part of so many lives. Vision plays an important role in sport performance, reaction time and color discrimination. This article will explore the visual needs of athletes and and how opticians can guide their patient athletes with the best lenses to help them perform at their optimum ability.


Sports eyewear, first and foremost, protect the eyes and help prevent injury. Sports in variable light conditions require a photochromic lens that changes with the amount of UV light emitted and received. By offering changeable polarized lenses, you meet the athlete’s need for lenses that reduce glare and help improve athletic performance. These unique lenses darken and polarize with the changing amount of light. Cyclists and hikers would benefit from this type of lens.

Motorcycle riders now have the option of a “light intelligence” shield. These helmet shields are clear at night and darken to a smoke gray in bright light. The shields also block 100 percent UV light and blue light.

Polarized lens reduce a significant amount of glare and help with reaction time for athletes. Amber lenses filter out blue light and are favorable for the baseball player, golfer, skier, and cyclist.

Gray lenses do not alter the color state of objects. These lenses are overall a good lens color choice for most sports on bright, sunny days. Many shooters prefer yellow lenses as they tend to enhance the contrast between the target and the background. Yellow lenses filter blue light and help the wearer achieve sharper focus, especially in hazy and low-light conditions.
