Virtual reality training improves accommodative facility and accommodative range.

ABSTRACT:

Aim

To evaluate the effects of virtual reality (VR) training on different parameters of vision.

Methods

Sixty individuals ranged 18-60 years old with asthenopia were randomly divided into short-term (n=40) and long-term (n=20) treatment groups. They were given a specially designed VR training device only once for 15min or 3-4 times a day for 15min each time for 1mo. The visual acuity, spherical equivalent, accommodative range, accommodative facility, pupil size, and visual fatigue were evaluated before (control) and after VR training.

Results

The visual acuity, accommodative range, and accommodative facility increased in subjects of the short-term treatment group, whereas their pupil size contracted significantly. No significant changes in spherical equi
