Study of the Kinetic Visual Acuity : Influence of the Training of Accommodation of the eye upon the Kinetic Visual Acuity

Abstract

In order to achieve accommodation of the eye which influences predominantly upon the kinetic visual acuity which chiefly relates to the accuracy in the timing action, the following studies were performed; that is, at the certain period of time, training to the velocity of accommodation was done repeatedly in every day, and the effect of training and the variations in the kinetic visual acuity accompanying with the training effect were determined. The results were obtained as described here, 1) By the training of accommodation of the eye, the accommodative contraction time shortened and the higher value of the kinetic visual acuity was obtained. 2) Relationship between the daily change in the accommodative contraction time and that in the kinetic visual acuity was due to chiefly to the degree of training for the optimal reaction to the moving object, where the subject himself performed in his daily life.
