How to Avoid Digital Eye Strain

Posted by David Johntson on April 30th, 2018

Computer Vision Syndrome - commonly known as digital eye strain - is now the most common computer-related repetitive strain injury worldwide, with major implications on productivity, bottom-lines and overall health. 

Caused by over-use of digital screens, CVS can result in blurred vision, irritation, back pain, neck pain, eye strain and headaches, yet only 1 in 5 adults is aware of the condition or how to avoid it. Similarly, many employers aren't aware of it, meaning they're not putting in place steps to help their staff avoid this common problem. 

This is surprising, considering the impact on businesses - in terms of lost productivity and staff sick days - can be significant. More than 83% of Americans use a digital device for more than two hours per day, putting them at risk of CVS, and 32.6% of those report experiencing eye strain. 

So how can you avoid digital eye strain? Luckily, there are some simple steps you can take to limit the impact of CVS, as outlined in this beautiful graphic from UK prescription glasses specialist Glasses Station. If you regularly use digital devices and want to ensure you don't experience digital eye strain, you should: 

• Drink at least 1.2L of water per day to help prevent dryness of the eyes
• Take regular breaks from the screen
• Eat foods such as fatty figh, onions, garlic and blueberries to help keep your eyes healthy
• Change the font sizes and resolutions on your screen to ensure you can see them comfortably
• Remember to blink! Blinking is halved when looking at computer screens, which contributes to our eyes being dryer than normal
• Ensure working spaces are comfortable and you're not straining your neck and back to work at a computer
• Make sure your screen is a comfortable distance from your eyes

You can also follow the 20-20-20 rule, which states that every 20 minutes, you should take a 20 second break and look at something that's 20 feet away from you. This helps to relax your eyes and refocus them, and can help prevent digital eye strain if done every day.
