Abstract

Methodology:BCVA of minimum 6/9, N8 (0.17 LOG MAR, 1.0M) and stereo acuity 60 Secs of arc were included.All subjects played 3D mobile game for 30 minutes without any interval with working distance of 40 cm.The refractive error was obtained before playing the 3D game, and at the end of 30 minutes using both retinoscope and Autorefractometer . If any myopic shift was observed in any subject after 30 minutes, then an objective refraction was to be performed after every 3 minutes till the myopic shift resolves.

Results- Out of 50 subjects 12 subjects were in myopic group having mean refractive error of -2.31 ±1.03 D and non myopic group of 38 subjects had a mean refractive error of -0.075 ±0.35D.There was no statistical significant difference for myopic group with (p = 0.333521177) with myopic shift of -0.29D and non myopic group (p = 0.53167431) myopic shift of -0.031D.
