Eye black is a grease applie under the eyes to reduce glare. It is often used by baseball and American football players, where sunlight or stadium lights can impair vision of an airborne ball. Traditional grease consists of beeswax, paraffin, and carbon. Patented antiglare stickers that emulate the grease are also manufactured, sometimes with a sports team logo printed on. According to Paul Lukas of ESPN.com, the earliest known instance of a player wearing eye black is Washington Redskins fullback Andy Farkas, who apparently came up with the idea on his own in 1942. He also goes on to say that the original eye black was made from burned cork ashes.
