Pac-Man: Better than an eye-patch for some vision-impaired
In a novel use of video game playing, researchers at Ohio State have found a Pac-Man-like game, when played repetitively, can improve vision in both children and adults who have “lazy eye” or poor depth perception.
In the Pac-Man-style game, players wear red-green 3-D glasses that filter images to the right and left eyes. The lazy or weak eye sees two discs containing vertical, horizontal or diagonal lines superimposed on a background of horizontal lines. The dominant eye sees a screen of only horizontal lines. The player controls the larger, Pac-man-like disc and chases the smaller one. In another game, the player must match discs with rows based on the orientation of their lines.
