What is eyeblack for?

Eyeblack is a popular product used by athletes, especially in sports like football, baseball, and basketball, to reduce glare and improve vision on sunny days. It is a sticker or grease-based material that is applied under the eyes to reduce the sun's glare that reflects off the skin around the eyes.

Eyeblack can come in various forms, such as pre-cut stickers or a small tube of grease that can be applied with a finger. It is typically black in color, although some versions may come in other colors or with designs.

In addition to reducing glare, eyeblack is also believed to help improve focus and reduce eye strain by creating a contrasting barrier between the eyes and the sun or bright lights. Some athletes also use eyeblack as a form of intimidation or to reduce distractions while competing.

Overall, eyeblack is a simple yet effective tool that athletes use to enhance their performance and protect their eyes from the sun's glare during outdoor sports.
