In the digital age, computer screens and mobile devices have become essential tools for work, study and entertainment. However, prolonged exposure to screens can cause computer vision syndrome (CVS), also known as digital eye strain. This condition not only affects the eyes but also causes headaches, neck fatigue and reduced work performance.
According to Dr Digvijay Singh,philologist at Hiranandani Eye Hospital, Mumbai (India): About 70% of people who have used electronic devices for a long time have signs of computer vision syndrome. Changing your habits can significantly reduce this condition."
Typical symptoms of digital eye strain
People with computer vision syndrome often have common symptoms:
Dry eyes: a feeling of grimacing, burning, and reflex tearing.
Red eyes: appear persistent due to eye strain.
Sleepy eyes: heavy eyelids, difficulty concentrating to see for a long time.
Headache, pain around the eyes: often accompanied by incorrect sitting posture.
Loss of concentration: blurred vision or double vision after using the device.
If left unnoticed, these symptoms can persist, directly affecting eye health and quality of life.
5 tips from experts to prevent eye strain
To control digital eye strain, ophthalmologists recommend:
Optimizing screen size and distance: use a large screen, placed away from the eyes to reduce visual stress.
Adjust your light: maintain moderate brightness, avoid spotlight directly into your eyes.
Hold the correct posture: sit up straight, place the screen ngang nganguy or slightly lower than eye level.
Follow the 20-20-20 rule: every 20 minutes, look out 6 meters away for 20 seconds to rest your eyes.
Use the right glasses: anti-glare or prescription glasses to help reduce pressure on the eyes.
In addition, users should reduce their eyes with over-the-counter lubricating solutions, do eye relaxation exercises and have regular eye check-ups to prevent complications.
According to the American Academy of Ophthalmology (AAO), these simple measures not only help reduce eye strain but also contribute to long-term vision protection. The eyes are a window to health, so take the initiative to care for them before damage becomes difficult to recover, Dr. Singh emphasized.
