Prolonged video display terminal (VDT) use significantly impacts visual health, particularly concerning asthenopia (eye strain) and daily work hours. However, standard visual screening tests showed no significant differences between VDT users and non-users over five years.

Area of Science:

  • Ophthalmology
  • Occupational Health
  • Ergonomics

Background:

  • Video display terminal (VDT) use is prevalent in modern workplaces, posing potential risks to visual and musculoskeletal health.
  • Previous research suggests VDT work may induce visual discomfort and potentially alter visual functions.

Purpose of the Study:

  • To prospectively investigate the influence of VDT work on the visual system over a five-year period.
  • To compare visual function parameters between VDT workers and a matched control group of non-VDT office workers.

Main Methods:

  • A 5-year prospective, matched-pairs study involving 102 VDT workers and 102 controls.
  • Comprehensive visual examinations including visual acuity, phorias, stereopsis, color vision, slit-lamp biomicroscopy, funduscopy, tear film stability (break-up time), lacrimal secretion (Schirmer-I test), visual field testing (perimetry), and intraocular pressure measurement (tonometry).

Main Results:

  • A significant association was found between asthenopia and daily VDT work duration, with those working >6 hours reporting more symptoms.
  • While pre-existing exophoria showed a trend toward increase in VDT users, this was not statistically significant.
  • No statistically significant differences were observed in any of the standard screening visual parameters between the VDT group and the control group after five years.

Conclusions:

  • Daily VDT work duration is a significant factor for asthenopia, highlighting the importance of work-hour management.
  • Standard visual screening examinations may not detect subtle, long-term changes induced by VDT work.
  • Further research is needed to understand the long-term visual effects of VDT use, especially concerning binocular vision and accommodation.
