How does eye black work

Some of the details are also interesting. For participants with non-blue eyes, eye black provided a significant advantage in terms of contrast sensitivity. That was not the case for blue-eyed individuals. There was a marked difference in the effect of eye black on those with blue versus non-blue eyes. This law states that for a change in intensity to be noticeable, the change must be proportional to the original intensity.

In the case of glare arising from the cheeks, its effect in reducing contrast is proportional to the existing level of ambient glare. Blue-eyed individuals, because they have less iris pigment to screen out unwanted light, have a greater level of intraocular scatter light reflected within the eye than non-blue-eyed people. Thus, for blue-eyed individuals, glare arising from the cheekbones should be less detectable than for individuals with darker irises.

If glare is less detectable for the former, then eliminating or reducing it with eyeblack grease will have less of an effect than if the glare were more detectable, as is the case for non-blue-eyed people.

If you like the eye black stickers with team logos, the studies concluded that anti-glare stickers and petroleum jelly have zero impact as anti-glare products.

The studies indicate that wearing eye black can improve contrast sensitivity, presumably by reducing glare. This provides a potential advantage for those who participate in athletic activities. Traditional eye black manufacturers and sports companies produce eye black cheaply and overseas. These companies sell a vinyl eye black product that harms one's face and does not use breathable materials.

As you can see below, the competition's vinyl material stretches very easily and is not designed to withstand perspiration or adverse weather conditions. As a result, sweat easily degrades the vinyl adhesive, causing the product to fall off one's face within minutes. Look at the evidence. All Rights Reserved.

DeBroff said there was a roughly one level of sensitivity improvement between no products vs. Eye black grease and no-glare stickers have been used by professional baseball and football players for decades to reduce glare from sunlight and stadium lighting.

These light sources can affect an athlete's ability to see detail and sensitivity to contrast. Previous studies have shown that the higher an athlete's sensitivity to contrast, the better he or she can see an object as its speed increases.

DeBroff said anti-glare stickers, which are patented fabric materials, have become more popular because they don't smear and some are manufactured with team logos. His results show there is no benefit to their use.
