Summary
Computer vision syndrome (CVS) in preteens is linked to binocular vision issues. Children with severe CVS show more vergence disorders, suggesting optometric screening is crucial for preventing long-term effects.
Area of Science:
- Ophthalmology
- Pediatric Optometry
- Digital Health
Background:
- Digital device usage is prevalent among preteens.
- Computer vision syndrome (CVS) is increasingly recognized in younger populations.
- The impact of digital devices on preteen visual function requires further investigation.
Purpose of the Study:
- To assess computer vision syndrome (CVS) in preteens using a validated questionnaire.
- To evaluate the effects of digital device use on accommodative and binocular vision in this age group.
- To identify correlations between CVS severity and specific visual function parameters.
Main Methods:
- A cross-sectional study involving 309 preteens (ages 10-12).
- Utilized an adult-validated CVS questionnaire adapted for preteens.
- Conducted visual acuity tests, cover tests, and accommodative and vergence response assessments.
Main Results:
- Statistically significant differences in convergence and fusional vergence responses between mild and severe CVS groups.
- Children with severe CVS exhibited a higher prevalence of vergence disorders.
- Poor convergence skills were associated with reported symptoms during device use.
Conclusions:
- Preteen computer vision syndrome is associated with significant deficits in binocular vision, particularly vergence disorders.
- Optometric clinical screening can help mitigate ocular symptoms and prevent long-term visual complications.
- Early identification and management of visual dysfunctions are essential for children using digital devices.
