Stereoscopic eye exercises and visual acuity.

The present study was done to investigate the effects of stereoscopic eye exercises on visual acuity, testing 20 college students (9 men and 11 women, ages 18 to 35 yr.). Visual acuity was assessed before and after the exercises through six tests: far vision--both eyes, right eye; left eye; and near vision--both eyes, right eye, left eye. Statistically significant improvements were found on five of the six pretest-posttest comparisons: far vision--both eyes, right eye, and left eye; and near vision--both eyes, right eye, and left eye. Changes in far vision, right eye only approached significance. Limitations of the present study were discussed, and recommendations for research were presented.
