What is the 20-20-20 rule to prevent digital eye strain?

We spend half our day in front of the screen on laptops or mobile phones. This prolonged screen time can often lead to dry and irritated eyes, eye strain and other eye-related problems. Dr N S Muralidhar, President of the Vitreo-Retinal Society of India, said, “With over two billion people living with the eye condition worldwide, millions in India alone suffer from preventable vision loss.”

Some other significant causes include cataracts (responsible for 66.2 percent of blindness in individuals 50 years of age or older), glaucoma (damage to the optic nerve), and retinal disease (diabetic retinopathy, age-related macular degeneration), etc. are included. Muralidhar told indianexpress.com.

Contrary to these reasons, Dr Rishi Bhardwaj, Consultant, Ophthalmology, Paras Hospital, Gurugram said that staring at digital devices does not necessarily harm your vision. “But, it can result in discomfort and stress. The average person blinks 15 times every minute. This percentage drops to half or a third when viewing a screen. This can result in dry, itchy and puffy eyes. This is known as computer vision syndrome (CVS).”

Like, are there any exercises that can help prevent eye strain? It’s the 20-20-20 rule! Here’s how you can follow it: For every 20 minutes of screen time, look about 20 feet away in front of you for 20 seconds. “The aim is to reduce eye strain caused by glare on a digital screen for a long time. It is necessary to take frequent breaks from the screen to prevent computer vision syndrome,” explained Dr Muralidhar.

He added that this regimen effectively reduces eye strain and other symptoms resulting from prolonged screen time.

According to Dr. Bhardwaj, this “amazing technique” helps us to take frequent breaks from the screen. “This can reduce eye fatigue caused by extended use of digital screens,” he said.

Researchers suggest that any relief from frequent computer work or screen time is good, despite the fact that many doctors recommend following the 20-20-20 rule, the ophthalmologist explained.

Experts mentioned that anyone and everyone can follow this simple rule designed to reduce eye strain.
