Measuring the Visual Performance of Athletes

"The use of valid and repeatable visual acuity and contrast sensitivity tests is essential for measuring the differences in visual performance among athletes and nonathletes. The ability to improve already–normal visual acuity is unclear although contrast sensitivity can improve with fast–paced video games. Tinted contact lenses help reduce discomfort glare and speed up adaptation but do not have an appreciable effect on visual acuity and contrast sensitivity." That's the MDLinx abstract of study that appeared recently in Eye and Contact Lenses.
