Why your Eyes feel Tired & What You can do About It

In today’s digital world, many of us spend hours each day looking at screens for work, learning, or entertainment. As a result, eye fatigue, also known as digital eye strain, has become increasingly common. While eye fatigue is usually temporary, it can affect comfort, productivity, and overall wellbeing.

What is Eye Fatigue?

Eye fatigue occurs when the eyes become tired after extended periods of visual concentration. Common symptoms include:

  • Tired, sore, or burning eyes.
  • Dry or watery eyes.
  • Blurred vision.
  • Difficulty focusing.
  • Headaches.
  • Neck and shoulder discomfort.

Digital eye strain may affect more than half of regular computer users, making it one of the most common vision-related complaints in modern life.

Why Does it Happen?

Eye fatigue is often caused by a combination of factors

Extended Screen Use

When using digital devices, people tend to blink less frequently. Reduced blinking can lead to dry eyes and discomfort. Prolonged focusing on near objects can also place extra demand on the eye muscles, contributing to fatigue.

Poor Visual Ergonomics

Glare from screens, inadequate lighting, poor posture, and incorrect viewing distances can all increase visual strain.

Uncorrected Vision Problems

Even small vision changes can force the eyes to work harder, particularly during computer use or reading.

Practical strategies that can help alleviate discomfort and support long-term eye health include:

  • Following the 20-20-20 rule – Every 20 minutes, look at something at least 20 feet away for 20 seconds. This allows the eye’s focusing system to relax and may reduce symptoms of digital eye strain.
  • Blink more often – Conscious blinking helps maintain a healthy tear film and prevents eye dryness, a major contributor to discomfort during screen use.
  • Optimise your workspace – Position screens at a comfortable distance, minimise glare, and ensure adequate lighting. Good ergonomics can significantly reduce visual stress.
  • Take regular breaks – Incorporate regular breaks throughout the day to reduce eye strain and improve visual comfort. Simple pauses away from screens can make a meaningful difference.
  • Schedule regular eye tests – Routine eye examinations can identify vision problems that may contribute to fatigue and ensure that prescriptions are up to date.
