How Screen Fatigue Affects Productivity and Focus at Work
Screens have become an unavoidable part of modern work life. From computers and tablets to smartphones and virtual meetings, many professionals spend most of their day looking at digital screens. While technology enables efficiency, prolonged screen use often leads to screen fatigue, which quietly reduces productivity, focus, and overall well-being.
This article explains how screen fatigue affects productivity and focus at work, along with practical ways to manage it.
What Is Screen Fatigue?
Screen fatigue, also known as digital eye strain or mental screen overload, occurs when the eyes and brain are overstimulated by prolonged screen exposure.
Common causes include:
Long hours of continuous screen use
Poor lighting or screen glare
Small text and constant scrolling
Frequent notifications and multitasking
Over time, screen fatigue affects both physical comfort and cognitive performance.

Mental exhaustion
Increased irritability
These symptoms directly interfere with work performance and focus.
How Screen Fatigue Impacts Productivity
