Abstract—By relaxing the contracted focus-adjustment muscles around the eyeball, such as the ciliary and extraocular muscles, improvement of the pseudo-myopia is expected. This understanding has led to the accommodation training in which the visual target is given by stereoscopic video clips. In this study, we verify effects of the apparatus on eyesight of 12 middle-aged persons. The middle-aged were investigated on several trials of the eyesight recovering apparatus. As a result, the visual acuity was statistically improved by continuous accommodation training which will promote a ciliary muscle-stretching effect.

Index Terms—3D movie, visual function, middle-aged people.
