Introduction

Digital devices are part of everyday life, but extended screen exposure can influence visual clarity, focus, and overall eye comfort. Understanding how screens affect your eyes allows you to take preventive steps before discomfort becomes persistent.

How Screens Impact Vision

Common effects of prolonged screen time include:
