A Study of Accommodation Training by Stereoscopic Film Presentation
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 accommo-dation training in which the visual target is given by stereoscopic video clips. In this study, we verify short-term effects of the accommodation training on eyesight of visual inspection workers (22 females) suffering from eye fatigue and 12 middle-aged persons. In the Measurement 1, the workers were trained in 3 days. Moreover, the middle-aged were investigated on several trials of the eyesight recovering apparatus in the Measurement 2. In the Measurement 3, we verify the effects of the accommodation training on eyesight and asthenopia of the young. The accommodation training is compared with close work on VDTs. As a result, the visual acuity was statistically improved by continuous accommodation training which will promote a ciliary muscle-stretching effect.
