The Wertheim Foundation believes that this is an appropriate forum for vision testing, and this is the first of a series of videos to be available to the public. The red bar at the top of the screen should be 2.2 inches (5.6 cm) across and you should be standing 6 feet (1.8 m) away. If you cannot adjust the size of your screen, you should move proportionately nearer or farther.
