  • Look Inside

We studied the possible influence of head-mounted display system on visual functions in 31 healthy persons. They were asked to watch one movie using the system for 2 hours. The ages ranged under 34 years in 21 persons, between 35 and 45 years in 6 and over 51 years in 4. Each test subject underwent examinations for ophthalmological and subjective findings before and after watching the movie. Subjects in younger age group showed significant changes in refraction. Some showed changes in stereo acuity and corneal findings. The observed changes were slight and temporary. The findings seemed to show that use of head-mounted display does not cause problems of clinical consequence. Optical misalignment of the system did not influence the findings.
