New study finds excessive screen time causes dry eye in school children

New study finds excessive screen time causes dry eye in school children

 


Recent studies have found that dry eye disease is on the rise among school children due to increased screen time.

Researchers from BJ Medical College (BJMC), Ahmedabad, PDU Government Medical College, Rajkot and Government Medical College, Satna said children who use the devices for more than three to 3.5 hours a day are at higher risk of developing dry eye disease (DED).

Dry eye occurs when the eyes do not produce enough tears or tears evaporate too quickly, causing discomfort, redness, and blurred vision.

“Even an extra 30 minutes of computer use per day increases the likelihood of moderate to severe dry eye. Policy makers should aim to limit children's screen time to less than three hours per day,” the team wrote. Published in the Indian Journal of Ophthalmology.

The survey found that of 462 schoolchildren with an average age of 11 who underwent eye consultation at public hospitals, 90 percent suffered from mild to severe dry eye, which causes blurred vision, bloodshot eyes and itchy, watery eyes.

The condition is associated with 8-10 hours of screen time for recreational, extracurricular, and educational purposes.

Added to this, increased screen time and decreased blinking frequency created a double burden for the 20% of children diagnosed with moderate to severe cognitive impairment. Severe dry eyes.

Studies have shown that children with moderate to severe dry eye spend 60 to 70 percent more time looking at screens than children with normal eyes.

When asked about their screen time over a four-day period, they reported using the computer for 30 minutes to two hours for studying and 45 minutes to two hours for extracurricular activities. They used their mobile devices for study for between 45 minutes and two hours. There are 2-3.5 hours of recreational time each day.

According to a national survey by Common Sense Media, in 2017, 95% of children ages 0-8 used a mobile device, and 42% of young children owned their own tablet device.

Children under the age of eight spend an average of 2 hours and 19 minutes a day on screen media.

The study authors note that with a significant increase in children's access to and ownership of mobile devices (e.g., smartphones, tablets) over the past decade, the inevitable increase in digital media consumption among young people is creating new challenges for eye problems and digital eye strain from an early age.

The study said, “Parents, teachers and policymakers should aim to limit screen time to less than three hours per day and encourage children to follow the 20/20/20 rule – looking away from the screen every 20 minutes and focusing on an object at least 20 feet away for at least 20 seconds.”

The researchers advised that children should be encouraged to take frequent breaks, such as walking away from screens for at least 10 minutes every hour.

“Using a simple timer or software program to turn off screens at regular intervals can help children remember to do so,” the researchers wrote.
