Vision recovery training device

摘要

PPROBLEM TO BE SOLVED: To simplify the constitution of a visual acuity recovery training apparatus and to improve the training efficiency. PSOLUTION: A trainee alternately looks a near visual target (a video display part 13) in a state where a movable convex lens is laid and a distant visual target (a virtual image 13' of the video display part 13) in a state where the lens is erected. The movable convex lens 14 repeats (a) the laid state and (b) the erected state, for example, in five-second periods by the operation of a rotating electromagnet 14a. A part of an inspection window 12 through which the trainee looks is formed with a slot part 15 for attaching an additional lens (a convex lens) for adjusting the position of the near visual target or the distant visual target. A device, wherein a convex mirror and a plane mirror are selectively operated to make the video display part to the distant visual target (inverse to the illustrated device) and make its virtual image to the near visual target, is also disclosed. The illustrated device is more compact than the other. PCOPYRIGHT: (C)2005,JPO&NCIPI
