Football players have long painted black under their eyes, a practice known as "eye black."

This unique tradition has a rich history and significant impacts on both player performance and the game's cultural identity.

The primary purpose of eye black is to reduce glare from the sun and stadium lights, improving a player's vision and focus on the field.

By creating a contrast between the painted area and the surrounding skin, eye black helps filter out bright light that can otherwise impede a player's ability to track the ball and read the movements of their opponents. - https://perfectpaintpro.com/sports-culture/why-football-players-paint-black-under-their-eyes/?unique_id_gaavsjk7
