The Effect of Digital Devices on Visual Eye Health

Abstract

The widespread use of digital devices, including smartphones, tablets, and computers, has led to an increase in visual discomfort and related ocular symptoms among users. This study aims to examine the impact of prolonged screen exposure on visual eye health and identify the most common symptoms associated with digital eye strain (DES) or Computer Vision Syndrome (CVS). Evidence from recent studies shows that extended screen time contributes to dry eyes, blurred vision, eye fatigue, headaches, and accommodative stress. Environmental factors such as poor lighting and improper ergonomics further exacerbate these symptoms. Preventive measures, including regular breaks, correct posture, and optimized lighting, can significantly reduce the negative effects on visual comfort.
