Baseball players use eye black for glare reduction and tradition
Summary

Baseball players apply eye black under their eyes as part of their game preparation, a practice rooted in tradition and aimed at reducing glare from sunlight or stadium lights. While scientific studies suggest that eye black may offer some reduction in glare, its effectiveness varies. Some players prefer this method over sunglasses to maintain focus without the potential disruptions of eyewear during fast-paced plays. The tradition dates back to at least the mid-1900s and is a common part of many athletes' routines before games.
