    Patent number: 5436681
    Abstract: A vision screening apparatus and screening method that includes a myopic screening test image and a hyperopic screening test image. In one embodiment, each screening test image includes a test letter member superimposed on a colored background member that, in combination, form the myopic screening test image portion and the hyperopic screening test image portion. In a preferred embodiment, the myopic test image is formed by a test image member, such as a letter, superimposed on a red colored background. The hyperopic screening test image is formed by a test image, such as a letter, superimposed on a green colored background. Alternatively, the test images may be colored, while the background remains a neutral color.
