Effects of Head-Mounted Display on the Oculomotor System and Refractive Error in Normal Adolescents.

Purpose: To investigate the clinical effects of head-mounted display on the refractive error and oculomotor system in normal adolescents.

Methods: Sixty volunteers (age: 13 to 18 years) watched a three-dimensional movie and virtual reality application of head-mounted display for 30 minutes. The refractive error (diopters [D]), angle of deviation (prism diopters [PD]) at distance (6 m) and near (33 cm), near point of accommodation, and stereoacuity were measured before, immediately after, and 10 minutes after watching the head-mounted display.
