The Correlation Between Eye Strain on Visual Acuity with Refractive Error Among Children

Area of Science:

• Ophthalmology
• Pediatric Health
• Public Health

Background:

• Visual impairment is a major public health concern, particularly in children.
• Increased computer use among children contributes to eyestrain and visual discomfort.
• Uncorrected refractive errors are the primary cause of vision loss in children.

Purpose of the Study:

• To investigate the impact of interventions on eyestrain and visual acuity in children.
• To assess the relationship between sociodemographic factors, eye health, and convergence insufficiency symptoms.
• To evaluate the effectiveness of a treatment on reducing refractive error and improving visual function.

Main Methods:

• A true experimental study involving two groups: an experimental group (n=85) and a control group (n=85).
• Data collected through structured questionnaires assessing sociodemographic and eye health variables.
• Convergence Insufficiency Symptom Survey used to measure symptoms.

Main Results:

• The experimental group showed a significant reduction in eyestrain and refractive error, with improved visual acuity (P < 0.001).
• Participants in the experimental group experienced a mean reduction of -0.5 diopters in refractive error.
• The control group did not exhibit significant improvements in visual acuity or refractive error.

Conclusions:

• Children experiencing eyestrain show impaired visual acuity, linked to sociodemographic and eye health factors.
• Interventions can effectively reduce eyestrain and refractive errors in children.
• Addressing convergence insufficiency symptoms is crucial for improving visual health in pediatric populations.
