Since the umpire and batter need to be able to see a pitcher's eyes, a pitcher wearing sunglasses is up to the umpire. If the lenses are too dark, or the mirror coating is distracting to the batter, the umpire will ask the pitcher to remove their sunglasses.
Base runners must wear properly when running bases. High School coaches must not allow players to wear eye black in a manner that taunts or threatens opponents. Smeared eye black all over the cheeks is not consistent with the sportsmanship aspect of high school sports.
Limit activity. Do not exercise or lift heavy objects for 48 hours. This could cause more bleeding under the skin.
It means that only through faith in God will you be saved. That will be the last message he - or any college or professional player - will send via eye black, because NFL and NCAA rules forbid players from marking their uniforms, which includes those small strips, in any way.
except, per MLB rules, pitchers aren't allowed to have any white on their sleeves while on the mound -- it would make it too difficult for batters to pick up the ball.
If the pitcher's undershirt sleeves are exposed, they shall not be white or gray. Compression sleeves that are solid black or solid dark colored shall be the only colors allowed to be worn by the pitcher below his elbow.
Black stripes are supposed to prevent glares from light by absorbing it. Mythbusters tested it and found that while eye black does not appear to reduce glare, it does improve the ability to differentiate between light and dark.
The rule is as follows “Rule 2, Section 17: Eye black must be one solid stroke with no logos/numbers/letters and shall not extend further than the width of the eye socket or below the cheekbone.”, which many players don't agree with.

(a) The pitcher's glove may not, exclusive of piping, be white, gray, nor, in the judgment of an umpire, distracting in any manner.
Eye black is a grease or strip applied under the eyes to reduce glare, although studies have not conclusively proven its effectiveness. It is often used by American football, baseball, softball, and lacrosse players to mitigate the effects of bright sunlight or stadium floodlights.
In Women's lacrosse, the eye black rules are the same as for the Men. College is a free zone, while high school and below are restricted.
Rhodopsin is very sensitive to light and is the primary chemical used by the cones when seeing in low light conditions. The problem is that rhodopsin is so sensitive to light that under normal light levels, the light deforms and deactivates (photobleaches) this chemical.
