Computer use causes frequent eye strain, visual disturbances, and dryness in office workers. Poor lighting and screen flicker significantly worsen these computer vision syndrome symptoms.
Area of Science:
- Occupational health
- Ophthalmology
- Human-computer interaction
Background:
- Computer use is prevalent among office workers.
- Prolonged computer use can lead to various eye symptoms.
- Workplace factors may influence the occurrence and intensity of these symptoms.
Purpose of the Study:
- To measure the prevalence and intensity of eye symptoms in office workers using computers.
- To investigate the relationship between computer use duration and eye symptoms.
- To identify other work-related factors contributing to eye discomfort.
Main Methods:
- A cross-sectional study involving 477 office workers from two cities.
- Data collected via questionnaires on work history and recent eye symptoms.
- Statistical analysis included chi-square tests and multivariate logistic analysis.
Main Results:
- Prevalence of eye strain was 50.7% in women and 32.6% in men.
- Visual acuity impairment affected 38.3% of women and 21.2% of men.
- Mucosal dryness/burning reported by 46.5% of women and 24.2% of men. Lighting intensity and screen flickering were significant factors.
Conclusions:
- Office workers frequently experience eye symptoms.
- Symptoms are associated with specific work environment characteristics.
