An exercise device for improving poor visual acuity is disclosed in which a subject must identify randomly chosen figures of minimal visual stimulus projected in a darkened chamber. Earphones are provided to aid in the isolation of the subject and provide audio feedback. The device provides effective treatment for certain eye conditions involving poor acuity and is particularly effective in treating the eye condition known as amblyopia.
