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. The use of a batter's background has been standard in baseball (as well as cricket) since at least the late 19th century. The batter's eye performs the same role at a baseball venue as the sight-screen does at a cricket venue, except that a cricket sight-screen is usually white in order to contrast with the dark red cricket ball. Alternatively a black screen is used to contrast the white Limited Overs cricket ball. Design and seating The batter's eye area is usually painted or otherwise decorated in black, dark green, or another color dark enough to allow batters to track the flight of the white ball. If there are seats behind center field, they are painted a dark color and are not occupied during baseball games, as the "black bleachers" section is directly in front of them. If fans were allowed to sit in this section, it would create a pitcher's advantage, in addition to raising the batter's exposure to danger, as it would make it more difficult for the batter to track the ball if a substantial number of fans were wearing white shirts. One example of a batter's background is the black area in the center-field bleachers section of the original Yankee Stadium, known as the Black Seats. At one time, there were seats where the black area was, but because of distractions the seats were removed and the area painted black. (Before the stadium's mid-1970s renovation, a batter's eye screen was often put up in front of the section.) At Fenway Park in Boston, the batter's eye is made by laying a tarp over a section of the center field bleachers. During day games, the seats will not be sold so the tarp can be laid down; however, during night games, when the batter is more likely to be able to see the ball regardless of the backdrop, the seats are sold. This has often created unusual seating arrangements during night games that
