Concerns about video display terminal (VDT) use and myopia progression are common. However, current literature shows no compelling evidence that VDTs significantly increase myopia risk compared to other near work.

Area of Science:

  • Ophthalmology
  • Optometry
  • Public Health

Background:

  • Adults express concerns regarding video display terminal (VDT) use and myopia development or progression.
  • This paper reviews existing literature on VDTs and potential causes of myopia.

Purpose of the Study:

  • To review the scientific literature on the relationship between VDT use and myopia.
  • To assess the impact of VDTs on visual fatigue and refractive error changes.

Main Methods:

  • Literature review focusing on VDTs, asthenopia, accommodation, and vergence.
  • Analysis of clinical studies on myopia progression and transient myopia in VDT users.
  • Consideration of television viewing as a risk factor for juvenile myopia.

Main Results:

Related Experiment Videos

  • Asthenopia is reported more frequently (1.4-1.5 times) with VDT use than conventional office work.
  • Proofreading efficiency is lower on VDTs compared to printed materials.
  • While VDT use can cause transient fatigue-related accommodation and vergence changes, accommodative response to screens remains accurate.

Conclusions:

  • No conclusive evidence links adult VDT use to a significant increase in myopia onset or progression compared to other near work.
  • Further research is needed to address confounding variables like work hours in VDT user studies.
