  • Abstract
  • Look Inside

A new accommodo-polyrecorder was construc-ted which can successively measure the acco-mmodation time by alternately placing the target image at the near point of the test sub-ject and at the distance of 40cm to 5 m in re-gular stages.

1. Experiments in myopia or pseudomyopia has shown that the curve of accommodation time as well as contraction and relaxation time decreases when the target is placed at a dis-tance. When the target is placed farther, the relaxation time is rapidly prolonged. The in-crease of relaxation time is greater in pseudo-myopia than in myopia.
