Here’s Why Too Much Computer Screen Time Makes Your Eyes Hurt So Bad

With the digital age in full swing, it’s becoming increasingly difficult to avoid prolonged periods of screen time. Whether it’s for work, study, or leisure, many of us find ourselves glued to our computer screens for hours on end. But have you ever wondered why your eyes start to hurt after staring at the screen for too long? In this article, we will explore the reasons behind this modern discomfort and provide you with tips to protect your eyes.

The Effects of Blue Light

Blue light is a type of high-energy visible light that digital screens emit in large amounts. While it has its benefits during daylight hours, prolonged exposure, especially before bedtime, can disrupt your circadian rhythm and strain your eyes.

Computer Vision Syndrome

Computer Vision Syndrome, also known as Digital Eye Strain, encompasses a range of eye and vision-related problems resulting from prolonged computer use. Symptoms include eye discomfort, fatigue, blurred vision, and headaches.

Improper Ergonomics and Screen Settings

The way you sit and how your computer screen is set up can significantly impact your eye health. Poor ergonomics and inappropriate screen brightness or contrast can contribute to eye strain.

Infrequent Blinking

Did you know that on average, we blink about 15 times per minute? However, studies have shown that we blink less than half as much while using computers and other digital devices, leading to dry and tired eyes.

Preventing and Relieving Eye Strain

Fortunately, there are several ways to prevent and relieve eye strain, such as following the 20-20-20 rule, adjusting your workspace ergonomics, and using computer glasses or screen filters.


What is the 20-20-20 rule for eye strain?

The 20-20-20 rule suggests that for every 20 minutes spent looking at a screen, you should look at something 20 feet away for at least 20 seconds to reduce eye strain.

Can adjusting screen brightness reduce eye strain?

Yes, reducing screen brightness to match the ambient lighting in your room can help minimize eye strain.

Are there specific glasses for computer use?

Yes, computer glasses with anti-reflective coating and blue light filtering can help reduce eye strain.

How often should I take breaks from the screen?

It is recommended to take short breaks every hour in addition to following the 20-20-20 rule to give your eyes a rest.

Can eye strain cause permanent damage?

While eye strain can be uncomfortable, it typically does not lead to permanent eye damage. However, it is important to take steps to protect your eyes and reduce discomfort.
