For many years, athletes have been wearing a black substance under their eyes. The ability of this substance to enhance an athlete's performance has never been tested. This paper will address the ability of this substance to increase contrast sensitivity. Three different glare reducing skin coatings were photometrically tested to determine the product with the lowest gloss index. Utilizing the Arden Plates, contrast sensitivity (CS) was measured on 55 subjects ages 22-40 in a high glare environment both with and without the most effective glare reducing product. When wearing the glare reducing skin coating, subject's CS increased significantly at the spatial frequency of 0.8 cpd, under our test conditions.
