With the rise of technology, digital devices have become a part of everyday life. From working on computers to scrolling through social media on smartphones, many people spend hours in front of screens. While technology has improved productivity and connectivity, excessive screen time has led to an increase in digital eye strain—a condition that causes discomfort, dryness, headaches, and blurred vision.
What Is Digital Eye Strain?
Digital eye strain, also known as computer vision syndrome, refers to a collection of eye and vision-related problems caused by prolonged screen use. It occurs when the eyes are exposed to the bright light of screens for long periods, leading to fatigue and discomfort. Symptoms may include dry eyes, difficulty focusing, headaches, and neck or shoulder pain.
The Impact Of Increased Screen Time
Research shows that over 50 per cent of computer users experience symptoms of digital eye strain, and the numbers continue to rise as remote work and online activities increase. Our eyes were not designed to stare at digital screens for long periods, and prolonged exposure to blue light from screens can contribute to eye fatigue, dry eyes, and even disrupt sleep patterns. Blue light exposure has been linked to sleep disturbances by interfering with the production of melatonin, a hormone that regulates sleep. This can lead to difficulties falling asleep or staying asleep, further impacting overall well-being.
Why Does Digital Eye Strain Happen?
When we look at screens for extended periods, our eyes tend to blink less, which reduces the natural moisture that protects the eyes. Moreover, the blue light emitted by screens can contribute to eye fatigue. The small text and pixelated images on screens can also make our eyes work harder to focus, increasing strain.
How To Protect Your Eyes From Digital Strain
Here are some effective strategies to protect your eyes from digital strain:
Follow the 20-20-20 Rule
To reduce eye fatigue, take a break every 20 minutes and look at something 20 feet away for at least 20 seconds. This gives your eyes a chance to rest and refocus.
Adjust Your Screen Settings
Increase the text size on your devices and adjust the brightness to a comfortable level. Some devices have blue light filters that can be turned on to reduce the amount of harmful blue light emitted.
Position Your Screen Properly
Make sure your screen is positioned at an arm’s length away and that the top of the screen is at or slightly below eye level. This reduces strain on the neck and eyes.
Use Artificial Tears
If you experience dryness, consider using lubricating eye drops to keep your eyes moist. Blinking frequently can also help prevent dryness.
Practice Good Posture
Maintaining a proper posture can prevent discomfort and neck strain. Sit with your back straight and shoulders relaxed, ensuring your screen is at the correct height and distance.
Take Regular Breaks
In addition to the 20-20-20 rule, ensure you take regular breaks throughout the day. Stand up, stretch, and walk around to avoid prolonged periods of screen time.
Wear Computer Glasses
Specialised computer glasses can help reduce glare, filter blue light, and improve contrast, making it easier on the eyes during extended screen use.
Maintain Good Lighting
Ensure your workspace is well-lit to avoid glare on your screen. Use natural light whenever possible, and avoid direct light sources shining on your screen.
Conclusion
While digital devices are integral to modern life, it is essential to take steps to protect your eyes from strain. By adjusting your screen habits, taking regular breaks, and maintaining proper posture, you can minimise the discomfort associated with prolonged screen use and keep your eyes healthy.
