“Red, yellow and amber-coloured lenses are being tested by Nike. The company believes they can help players see the ball better, particularly in bright sunlight.

Red colours are useful for baseball players because amber blocks out blue light – ”visual noise“ to vision experts – and red areas, such as the seams on a baseball, are accentuated.”
