Prevalence Of Computer Vision Syndrome In Our Health

Abstract

This review paper critically examines the contemporary body of research on digital eye strain (DES) arising from prolonged engagement with electronic devices, such as television screens, mobile phones, and laptops. Several ocular and visual symptoms resulting from use of digital devices are collectively known as digital eye strain (DES) or computer vision syndrome (CVS). Few studies exist on the prevalence of DES among young adults in the Eastern Mediterranean region. Drawing upon a diverse array of scientific studies, encompassing clinical trials and experimental inquiries, this review synthesizes current knowledge regarding the impact of extended screen exposure on critical visual parameters. Key topics explored include the impact of extended screen time on visual acuity, accommodation, and the development of symptoms such as eye fatigue, dryness, and discomfort. Additionally, attention is directed towards exploring the modulating influence of environmental factors, such as ambient lighting conditions and display characteristics, on the severity and manifestation of digital eye strain. We explore the mechanisms by which prolonged screen time impacts the eyes, focusing on factors such as reduced blink rate, increased accommodative stress, and blue light exposure. The review further analyses the spectrum of symptoms associated with DES, including dry eye, blurred vision, eye fatigue, and headaches.
