- Eye black
Eye black is a grease applied under the
eyes to reduce glare. It is often used by baseballand American footballplayers, where sunlight or stadium lights can impair vision of an airborne ball. Traditional grease consists of beeswax, paraffin, and carbon.

According to Paul Lukas of ESPN.com, the earliest known instance of a player wearing eye black is Washington Redskinsfullback 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.
A 2003 study by Brian DeBroff and Patricia Pahk tested whether black eye grease actually had anti-glare properties. The subjects of the study were divided into three groups: wearers of eye black, wearers of antiglare stickers, and wearers of
petroleum jelly. The subjects' vision was tested using an eye chartwhile being exposed to natural sunlight. The study concluded that eye black reduced glare of the sun and improved contrast sensitivity, whereas commercial antiglare stickers and petroleum jelly (the control substance) were found to be ineffective.
