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

BACKGROUND

Visual impairment is a significant public health problem. Computer use by children especially school-aged children is growing rapidly. In these decades, therefore, extensive viewing of the computer screen can lead to eye discomfort, fatigue, blurred vision and headaches, dry eyes, and other symptoms of eyestrain. But nowadays, in this hazardous situation, visual impairment in children has negative impacts on socio-emotional competence and academic development. Uncorrected refractive error is the leading cause of vision loss.

MATERIALS AND

METHODS

A true experimental study that met the inclusion criteria was randomly allocated into the study group (n = 85) and the control group (n = 85) sociodemographic variable and eye health variable assessed by structured questionnaire. Convergence insufficiency symptom survey assessed.

RESULTS

The experimental group exhibited a significant reduction in eye strain level and refractive error with improvement in visual acuity. In the post-test, the experimental group showed complete to moderate recovery compared to the control group. It showed the significance difference where P < 0.001. Pearson correlation analysis was used for refractive error between the groups. Refractive error was reduced - 0.5 diopters in each participants. There is a significant change in the experimental group considered as a P value < 0.001 statistically significant, respectively. In contrast, the control group had no significant improvement in visual acuity reduction in refractive error.

CONCLUSION

This finding concludes that the children were having eye strain, which impacts the visual acuity could be incorporated with sociodemographic variables and eye health variables with convergence insufficiency symptoms among participants.
