[A new method for accommodation training]

A new method for accommodation training making use of a computer is proposed. A specially generated dynamic grid of concentric rings serves the stimulus. Changes of the accommodation parameters (the nearest and farthest points of clear vision) were examined in 11 display users aged 30 to 50 during a training session and in the course of 15 sessions. The training improved the accommodation volume by an average of 0.9 diopters at the expense of approximating the nearest and withdrawing the farthest clear vision points. In 4 subjects anisoaccommodation disappeared almost completely. The proposed method may be used to normalize the accommodation of display users.
