Journal of the American Optometric Association
|August 1, 1995
Summary
Most computer users experience vision problems like eyestrain and headaches. This study identifies the typical video display terminal (VDT) user and their common symptoms, paving the way for better optometric care.
Area of Science:
- Ophthalmology
- Occupational Health
- Human-Computer Interaction
Background:
- Workplace use of video display terminals (VDTs) is increasing.
- Associated visual problems are a growing concern for optometric practitioners.
- Understanding VDT user characteristics is crucial for effective treatment.
Purpose of the Study:
- To examine demographics, symptom prevalence, and vision-related factors among VDT users.
- To identify characteristics of a typical patient experiencing computer vision syndrome.
- To inform the development of targeted treatment protocols.
Main Methods:
- Data collected by 22 optometrists from 324 VDT users (≥2 hours/day).
- A questionnaire gathered information on dry manifest refraction and self-reported symptoms.
- Included patient demographics, VDT usage patterns, and visual complaints.
Main Results:
- The typical VDT user is a 38-year-old, mildly myopic female using a computer ~5 hours/day.
- Average VDT work experience is 5 years; most use color screens at 21-22 inches.
- Common symptoms include eyestrain (65%) and headaches (42%).
Conclusions:
- A high percentage of regular VDT users (75-88%) experience symptoms.
- This study characterizes the typical VDT user and their reported symptoms.
- Further research should focus on diagnostic and treatment protocols for computer vision syndrome.
