Purpose: To investigate the effect of watching 3-dimensional (3D) television (TV) on refractive error in children.
Methods: Sixty healthy volunteers, aged 6 to 12 years, without any ocular abnormalities other than refractive
error were recruited for this study. They watched 3D TV for 50 minutes at a viewing distance of 2.8 meters.
The image disparity of the 3D contents was from -1 to 1 degree. Refractive errors were measured both before
and immediately after watching TV and were rechecked after a 10-minute rest period. The refractive errors
before and after watching TV were compared. The amount of refractive change was also compared between
myopes and controls. The refractive error of the participants who showed a myopic shift immediately after
watching TV were compared across each time point to assure that the myopic shift persisted after a 10-minute rest.
Results: The mean age of the participants was 9.23 ± 1.75 years. The baseline manifest refractive error was
‑1.70 ± 1.79 (-5.50 to +1.25) diopters. The refractive errors immediately after watching and after a 10-minute
rest were ‑1.75 ± 1.85 and ‑1.69 ± 1.80 diopters, respectively, which were not different from the baseline values.
Myopic participants (34 participants), whose spherical equivalent was worse than ‑0.75 diopters, also did
not show any significant refractive change after watching 3D TV. A myopic shift was observed in 31 participants
with a mean score of 0.29 ± 0.23 diopters, which resolved after a 10-minute rest.
Conclusions: Watching properly made 3D content on a 3D TV for 50 minutes with a 10-minute intermission at
more than 2.8 meters of viewing distance did not affect the refractive error of children.
