The Effect of Using Head Mounted Display on Human Eyes

ABSTRACT

In order to investigate the effect of head mounted display (HMD) on the human eye, the authors performed ophthalmologic examination on normal persons, dry eye patients and strabismus patients before and after use of Glastron, i-glasses, LGHMD(PT),LGHMD10 for two hours once or for five consecutive days, respectively. There were no substantial changes in visual acuity, color vision, intraocu-lar pressure, and tear secretion before and after use of HMD. There were transient changes in terms of corneal curvature, refraction, stereopsis, the angle of strabismus, and accommodation. There existed no difference according to the kinds of HMD. In conclusion, there was no permanent ocular changes with use of four kinds of HMD for two hours once or for five consecutive days.
