New Delhi: In today’s digital world, people spend hours on screens for work, communication, and entertainment, leading to a rise in digital eye strain, also known as computer vision syndrome (CVS). Ophthalmologists are increasingly addressing this issue, which can cause discomfort and, if left unchecked, harm long-term eye health. This article explores the causes, symptoms, and prevention strategies for digital eye strain.
In an interaction with News9Live, Dr Sukanya Meikandasivam, Consultant – Ophthalmology, Gleneagles BGS Hospital Kengeri, Bengaluru, answered all FAQs about this condition.
Causes of Digital Eye Strain
Digital eye strain is primarily caused by prolonged screen exposure. Several factors contribute to this:
Extended Screen Time: Long hours of focusing on screens tire the eyes, as they struggle to maintain constant focus.
Poor Lighting and Glare: Inadequate lighting or excessive glare forces the eyes to strain, causing discomfort.
Improper Viewing Distance: Holding devices too close or at awkward angles increases strain on the eye muscles.
Reduced Blinking: People tend to blink less when using screens, leading to dry and irritated eyes.
Blue Light Exposure: Digital screens emit blue light, which can cause strain and interfere with sleep when used excessively, especially at night.
Symptoms of Digital Eye Strain
Common symptoms of digital eye strain include:
Eye Fatigue: The eyes feel tired and strained after prolonged use.
Blurred Vision: Difficulty focusing on the screen or objects can lead to temporary blurred vision.
Dry Eyes: Reduced blinking causes dryness, redness, and irritation.
Headaches: Frequent eye strain can trigger tension headaches.
Neck and Shoulder Pain: Poor posture while using screens may lead to neck, shoulder, and back pain.
Light Sensitivity: Some individuals become more sensitive to light, making bright environments uncomfortable.
Prevention and Management Strategies
There are several effective ways to prevent and manage digital eye strain, as recommended by ophthalmologists.
Follow the 20-20-20 Rule: A simple method to reduce eye strain is the 20-20-20 rule. Every 20 minutes, take a 20-second break to look at something 20 feet away, allowing the eye muscles to relax.
Adjust Screen Settings: Reducing screen brightness and adjusting the contrast to match the surrounding environment can make screen viewing easier. Blue light filters, especially in the evening, also help reduce strain.
Blink More Often: Consciously blinking more during screen use helps keep the eyes lubricated. Using lubricating eye drops, or artificial tears, can also help with dry eyes.
Optimize Lighting: Proper lighting is essential for reducing eye strain. Make sure your workspace is well-lit and that screen glare is minimized. Anti-glare screen filters can also be helpful.
Maintain Proper Screen Distance and Posture: The optimal screen distance is about 20 to 28 inches (50-70 cm) from the eyes, with the screen positioned slightly below eye level. Good posture—sitting upright with shoulders relaxed—helps prevent neck and back strain.
Limit Screen Time: Reducing overall screen time and taking regular breaks helps minimize digital eye strain. Incorporate non-screen activities into your routine to give your eyes a rest.
Use Prescription Glasses: If you wear glasses, ensure that your prescription is up to date. Computer glasses with an anti-reflective coating can reduce glare and blue light exposure. Consulting an ophthalmologist can help determine the right eyewear.
Conclusion
As screen time becomes an integral part of daily life, digital eye strain is becoming a widespread health concern. Understanding its causes and symptoms allows individuals to take proactive measures to protect their eyes. By following prevention strategies such as the 20-20-20 rule, adjusting screen settings, and ensuring proper posture, it is possible to significantly reduce eye strain. Regular visits to an ophthalmologist can help ensure your eyes stay healthy in a world dominated by screens.
