The batter's eye or batter's eye screen is a solid-colored, usually dark area beyond the center field wall of a baseball stadium, that is the visual backdrop directly in the line of sight of a baseball batter, while facing the pitcher and awaiting a pitch. This dark surface allows the batter to see the pitched ball against a sharply contrasted and uncluttered background. Its purpose is the safety and hitting success of the batter.[1] The use of a batter's background has been standard in baseball since at least the late 19th century. The batter's eye performs the same role in baseball as the sight screen does in cricket.
