The area is usually painted or otherwise decorated in black or dark green or some other 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 an unfair 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 Yankee Stadium, known as the Black Seats. At one time, there were seats where the black area is now, 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 large black 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 are made up during part of a day-night doubleheader as the sections remain uncovered for the people who have purchased the seats. The Red Sox have solved this problem by handing out T-shirts of the same color to these fans to wear during the game.

At Wrigley Field, the centerfield bleachers used to be closed off and covered by a tarpaulin, and later by juniper plants. There is now a shaded luxury suite there referred to by the Cubs as the "Batter's Eye Suite". [1]

Some stadiums have rotating billboards in this area. In this case, advertisements are displayed in between innings, while a dark surface is rotated in while the game is in play. This method was used at Shea Stadium in New York,[1] and at PETCO Park in San Diego. [2]

Tropicana Field in St. Petersburg, Florida has a restaurant called the Batter's Eye Restaurant.[2] New Yankee Stadium is scheduled to have a restaurant with dark tinted glass that will serve as the batter's eye.

For our application a batters eye is made out of some kind of windscreen material, and then hung on chain link fence, or on a frame of some kind. Any of the three materials sold for windscreens can be utilized as a batter’s eye. The darkest screens are better for allowing hitters to pick up the flight of the ball. The more opaque you get on the screen, the more pressure you put on the structure holding it up. However, the more air that can get through it, the more hitters will have trouble seeing the ball flight. Consequently there is a trade off on how opaque a batters eye should be. A lot of it is dependent on how tall the screen is. To eliminate some pressure, air vents might be utilized. No logos should be employed on a batter’s eye.
