How can I alleviate eyestrain associated with my computer use?
Understanding Digital Eye Strain
In today's digital age, many of us spend a significant portion of our day looking at screens – whether it's for work, education, or entertainment. While technology offers incredible convenience, prolonged screen time can lead to a common and often uncomfortable condition known as digital eye strain, also referred to as computer vision syndrome.
What is Digital Eye Strain?
Digital eye strain is a group of eye and vision-related problems that result from prolonged computer, tablet, e-reader, and mobile phone use. It's not a single eye problem, but rather a range of symptoms that can affect your comfort and vision. The average person blinks less frequently when looking at a screen, which can lead to dry eyes. Additionally, the eyes have to work harder to focus on pixels on a screen compared to printed text, and glare from screens can also contribute to discomfort.
Common Symptoms of Digital Eye Strain
The symptoms of digital eye strain can vary from person to person, but some of the most common include:
•
Eyestrain: A feeling of fatigue or soreness in the eyes.
•
Headaches: Often felt in the forehead or temples.
•
Blurred Vision: Difficulty focusing on objects, especially after prolonged screen use.
•
Dry Eyes: A gritty, burning, or itchy sensation, sometimes accompanied by redness.
•
Neck and Shoulder Pain: Poor posture while using digital devices can lead to discomfort in these areas.
•
Light Sensitivity: Increased sensitivity to bright lights.
Tips for Preventing and Relieving Digital Eye Strain
Fortunately, there are several simple steps you can take to reduce your risk of digital eye strain and alleviate its symptoms:
•
Follow the 20-20-20 Rule: Every 20 minutes, take a 20-second break and look at something 20 feet away. This helps your eye muscles relax and reduces fatigue.
•
Optimise Your Workspace: Position your screen about an arm's length away (20-28 inches) and slightly below eye level. Ensure proper lighting to minimise glare on your screen.
•
Adjust Screen Settings: Reduce screen brightness to match the surrounding light, increase text size for easier reading, and adjust contrast for comfort. Consider using a matte screen filter to reduce glare.
•
Blink More Often: Make a conscious effort to blink frequently to keep your eyes lubricated. If needed, use artificial tears to combat dryness.
•
Take Regular Breaks: Beyond the 20-20-20 rule, take longer breaks every hour or two to stand up, stretch, and rest your eyes.
•
Consider Computer Glasses: If you spend many hours in front of a screen, specialised computer glasses can help reduce eye strain by optimising your vision for the specific working distance of your screen.
When to See an Optician
While these tips can be very helpful, if you continue to experience persistent or severe symptoms of digital eye strain, it's important to schedule an eye examination with a qualified optician. They can assess your vision, check for any underlying eye conditions, and provide personalised recommendations, including prescription lenses tailored for computer use. Regular eye check-ups are crucial for maintaining good eye health in our increasingly digital world.
Please note that our opticians cannot provide a diagnosis when a face-to-face consultation with a medical practitioner is required. Any advice given should not replace medical care or an in-person consultation from a qualified practitioner. If you are experiencing sudden changes in vision, eye pain, or other concerning symptoms, please contact your optometrist or GP immediately.
