Influence on visual function by a stereoscopic TV programme with binocular liquid crystal shutter and Hi-Vision TV display.
Influence on visual functions by field sequential stereoscopic Hi-Vision TV programme with liquid crystal shutter were investigated in 24 subjects. Ocular alignment, fusional amplitude, AC/A ratio, stereoacuity, accommodation and pupil size were measured before and after the visual load. Symptoms related to asthenopia were also examined. No significant difference were found, although two aged subjects showed large changes in a few of these functions. This type of 3-D display may not be hazardous to visual functions, although further study may be required for aged or visually handicapped people.
