The Impact of Screen Time on Eye Health: Clinical Implications and Prevention

A Literature Review

Abstract

The increased use of digital devices has led to a surge in screen time, significantly impacting
eye health. The effects include computer vision syndrome, digital eye strain, and a rise in
myopia, particularly among children.Objective: This article aims to evaluate the impact of
screen time on eye health, identify the underlying mechanisms, and summarize effective
prevention strategies.Methods: A literature review was conducted on scholarly articles
published since 2020, using databases such as PubMed, Scopus, and Google Scholar. The
search focused on epidemiological studies, physiological mechanisms, and mitigation efforts
related to screen time.Results: Studies indicate that increased screen time is associated with a
rise in eye complaints, such as dry eyes, visual fatigue, and accommodation disorders. Risk
factors include blue light exposure, improper viewing distances, and prolonged device usage.
Prevention measures such as the 20-20-20 rule, blue light filters, and ergonomic workplace
adjustments have proven effective in reducing symptoms.Conclusion: Excessive screen time
negatively affects eye health, particularly among the younger population and office workers.
Public education and the implementation of preventive strategies are needed to minimize this
impact.
