why do people put black lines under their eyes

One of the earliest known instances of a player wearing eye black is baseball legend, who, in or around the 1930s, used the grease in an attempt to reduce sun glare. According to Paul Lukas of, eye black caught on with
player. He also states that the original eye black was made from the ashes of burned cork. 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 anti-glare stickers, and wearers of. The subjects\’ vision was tested using an while being exposed to natural sunlight. The study concluded that eye black reduced glare of the sun and improved sensitivity, whereas commercial anti-glare stickers and petroleum jelly (the control substance) were found to be ineffective. However, the study was subject to unavoidable, wherein the test subjects could have unconsciously changed their responses during testing based on the fact that they knew which substance they were wearing. Also, the petroleum jelly could have introduced glare that would not occur on natural skin and the study did not test a control condition of natural skin. is also a factor in the results due to chart repetition. A study by Benjamin R. Powers at, which improved on DeBroff\’s methodology, found eye black to reduce glare from the sun in females and in those whose eye-color was not blue.

The study also tested males and blue-eyed subjects. However, the results were not statistically significant (probably due to a smaller sample size of those test subjects). Some testing was also performed indoors under artificial lighting (when inclement weather prohibited outdoor testing). However, those results showed little difference and were not statistically significant. The Powers study was not a study because those in contact with the test subjects knew which substance was applied. Also, the eye tests were performed at a distance of only 1. 15 meters. On an episode of, and tested whether eye black reduces glare. They determined that, while eye black does not eliminate glare, it does improve an athlete\’s ability to differentiate between light and dark, enhancing a player\’s ability to track moving objects in a sunny environment. Why do american football players wear (what appears to be) black greasepaint stripes on their faces? Supposedly to attract the sunlight away from the eyes, but I suspect that the real reason is that it makes them look mean motherf*****s who aren\’t to be messed with.

To dull the reflection from sweat that gathers on the cheak below the eyes: wearing both gloves and a helmet that shields the face, it\’s hard for the already porcine fingers of the average football player to wipe the glistening face. It\’s not just American football players who wear it now; some goalkeepers are also doing so. It\’s designed to keep the sun out of one\’s eyes. I don\’t know much about American Footballers, but the Turkey and Barcelona goalkeeper Rustu Recber also sports this \’war paint\’ under his eyes. He claims the reason is that the paint lessens the glare of stadium floodlights which can be dazzling, although I suspect it\’s really just to look scary. I play football and i wear eyeblack because it helps the glare from the lights to stay out of my eyes. The looking like a mean MF is just a bonus. They wear it to keep the sun out of their eyes and it\’s like their war paint – as if they were going to battle. I played football and we put black greasepaint or black stripes under our eyes to keep the glare from the sun or field lights out our eyes, allowing us to see the ball when it\’s in the air. GO SAINTS!!! 2 main reasons from a practical pov, the first is to take the glare reflection off the skin which can distort depth perception (hence why the new strips are called \”glare strips).

The second is to give the QB a second set of \”eyes\”, defensive players watch the QB/WR\’s eyes to see where they are focusing to try to anticipate the play direction. The strips acts as a distraction (many have light points in the middle) to confuse or distort people looking at the QB\’s eyes. I think its more of an ego trait than a scientific theory. They should wear shades to go with the rest of the unnecessary over the top American regalia. eeehhhhh rugby!! The Laws of Optics state that with specular reflection (smooth surfaces such as a mirror)the angle of incidence equals the angle of reflection. Thus if a football player\’s check was struck by light from above it would be impossible to reflect that light back up into his eyes. However, the player\’s check is not a smooth surface but rather is an organic irregular surface. Dealing only with the irregularity of that surface the reflections would be at multiple angles from the multiple irregular surfaces. However, each surface would still be governed by angle of incidence/reflection rules. In the case of human skin, the light can pass through skin surface and be reflected from the internal surface resulting in diffuse reflection consisting of multiple angles of reflection.

Multiple internal reflections CAN cause the incident light to be reflected as a Reflex angle of 330-358 degrees that COULD reach the human cornea. This would amount to at most 1% of the incident light and thus would be insignificant to sportsmen or women. The black paint/patches on the cheeks are an affectation only. This study seems to disagree with the previous poster. The Ability of Periorbitally Applied Antiglare Products to Improve Contrast Sensitivity in Conditions of Sunlight Exposure Background: Sun glare decreases athletes\’ contrast sensitivity and impairs their ability to distinguish objects from background. Many commercial products claim to reduce glare but have not been proven effective in clinical studies. Objective To determine whether glare-reducing products such as eye black grease and antiglare stickers reduce glare and improve contrast sensitivity during sunlight exposure. http://archopht. jamanetwork. com/article. aspx? articleid=415492 They wear it because they secretly like wearing make up. In ancient times it was professed by that great Egyptian prophet that there would one day once again be grown powerful men wearing makeup he called them fagqis hence where the modern day gay term FAG comes from.
