Before the invention of Nike contact lenses, the only way athletes could block the sun from their eyes was through sunglasses. This in itself was very inconvenient, especially for sports requiring a lot of running or jumping movement. There was always the potential that the sunglasses could come off and/or get scratched while the athlete was at play. With Nike contact lenses, this worry would become nonexistent.

What are Nike contact lenses?

Nike contact lenses are a special type of contact lenses that use a light-filtering tint to improve the focusing power of the athlete’s vision. They can be used whether or not a person has developmental visual problems.

Nike contacts come in four different tints: golf tint, hi-vis tint, speed tint and polarized tint. Golf tint, just like its name suggests, is designed for being able to better see the grass and the ball while one is going golfing. The specific colors that one can see clearer with golf tint are green, red and blue.

Hi-vis tint is designed to see things better in low light. It accentuates the color yellow.

Speed tint, which works well while on the road, filters out colors that contribute to glare while putting an emphasis on the color red.

Polarized tint, useful for water sports, gets rid of the glare given off of reflective surfaces. Nike.com recommends to not use their polarized line if one is involved in sports where the head moves back and forth, because they might become distracted from the ‘pulsating effect’ given off by the lenses.

Nike contact lenses are available for all types of sportsmen through their various styles of lens tinting. Indeed, Nike contact lenses, allowing athletes to see in a way that is not possible through sunglasses or even their natural eye, has revolutionized sporting. In fact, the next time a superior athlete is observed, one should consider the fact that maybe a small portion of their superb performance could be due to how Nike contact lenses has affected their eyes.
