How to Prevent Eyestrain from Computers

According to an official study by Ofcom, 1 in 5 people spend more than 40 hours a week online, in front of a digital device. With more and more people using smartphones, tablets and computers, it seems that as we enter 2020, more and more people are having issues with their eyes, in the form of eyestrain. This blog is all about ideas on how to prevent eye strain from computers.

For a long time there has been concern over the effects that using digital technology has on eye health. You may remember the well-known childhood myth that warns children they’ll get square eyes if you stay in front of the TV? But if you’ve ever spent a long time in front of a computer or television that you might have some discomfort with your eyes, you’ll know that it can cause varying amounts of discomfort.

What is Eyestrain & How do I get it from Computers?

Eyestrain is caused by excessive use of computers and looking at computer screens or other digital devices. According to Medicine Net, eyestrain can occur after extended use of the eyes on digital screens, with symptoms including headaches, blurred vision, or dryness. This can be quite uncomfortable, but there is no evidence to suggest that eyestrain causes permanent damage to your vision.

People who look at screens for over 2 hours in a row have the greatest risk of getting eyestrain. But there are a few simple ways you can prevent eyestrain from computers affecting your daily life.

Distance from the Screen

You should make sure that your computer screen is at least 20 inches away from your eyes. Making sure that the top of the screen is level with your eyes. You should either do this by having a monitor stand that can be adjusted to suit your height, or by using an adjustable chair. This is also good for other parts of your body, it should stop you from slouching and causing back pain.


Making sure that the light around you isn’t too harsh is also important to make sure that the light from the computer screen doesn’t cause strain on your eyes. You should make sure that the lighting around you avoids a lower glare and harsh reflections. You can also have glare filters put over your digital screens which also help to reduce the risk of eyestrain.

Adjust Your Brightness Settings

If your computer screen is too bright or too dark, it can be straining for the eyes. You should always make sure that the brightness of your screen is the same as the brightness as the room you’re in. If it looks like the computer screen is more of a light source, it’s probably too bright. If you’re struggling to see using lower brightness settings, you can always change the contrast or text size of your computer.

Take Regular Breaks

According to all about vision, you should take at least one 10 minute break every hour that you’re in front of a screen. Other medical advice suggests to go by a 20-20-20 rule: Every 20 minutes, look at something 20 feet away for at least 20 seconds. You might be able to do this to keep a timer on your desk to make sure you’re making sure your eyes get regular breaks from the screen.

Need Any Help?

If you’re starting to find it difficult to look at a computer screen for long periods of time, you might want to consider getting a professional examination on your eyes. Getting glasses for use with your computer might help protect the health of your eyes.
