ABSTRACT:
A method and apparatus for increasing visual acuity of a person wherein a target is selectively moved toward or away from the person to different positions at accurately determined distances therefrom. At each of the positions, the person is required to identify the appearance of the target which is randomly changed to any one of a plurality of different appearances. The concept includes the moving of the target further away from the person whenever the identification of the target appearance is correct at a given position and moving the target closer to the person whenever the identification is incorrect. The invention comprehends moving the target incrementally at smaller distances away from the person than toward the person. A Badal lens is interposed between the person and the target for causing the focal points to be at the nodal point of the eye of the person. The target is illuminated with red light in the illustrated embodiment and is defined by line gratings wherein the different appearances of the target are provided by different diagonal line orientations. A display is provided for indicating to the user at all times the target distance and recording apparatus is provided for recording the respective distance and identifications for subsequent use in analysis of the visual training. The system is advantageously adapted for increasing the far-point acuity of a myopic person, as well as increasing the visual acuity of an emmetropic person.
