Rising screen time causing vision problems in children

Experts link digital device use to strain, dryness, and myopia

MULTAN:

The increasing use of mobile phones, tablets, and laptops is contributing to weak eyesight and other visual problems among children, a leading eye specialist has warned.

Dr Rashid Qamar Rao, Head of the Ophthalmology Department and Principal of Nishtar Medical College, said that although digital screens do not directly damage eyesight, their excessive and improper use is negatively affecting children's vision.

He noted a sharp rise in complaints of eye strain, dryness, headaches, and blurred vision among children.

"One of the main reasons is continuous and close-up viewing of screens," he explained.

According to Dr Rao, children tend to blink less while using screens, which leads to dryness of the eyes.

Prolonged focus on nearby objects can also weaken distance vision, a condition medically known as myopia.

He advised that mobile devices should be kept at least 12 to 14 inches away from the eyes, while laptop screens should be positioned slightly below eye level.

He also cautioned against using screens in the dark.

Dr Rao highlighted that blue light emitted from screens can disrupt children's sleep, especially when devices are used before bedtime. Lack of proper sleep can further affect eye health.

He urged parents to strictly limit their children's screen time and encourage daily outdoor activities.

"Children should be trained to follow the 20-20-20 rule — after every 20 minutes of screen use, they should look at something 20 feet away for at least 20 seconds to reduce eye strain," he said.

The specialist further stressed the importance of outdoor play, recommending that children spend at least one hour a day in open spaces.

A balanced diet is also essential for healthy eyesight, including green leafy vegetables, carrots, eggs, milk, and fish.

Parents should seek medical advice if a child frequently rubs their eyes, sits too close to the television, or complains of headaches, he added.

"In the digital age, complete avoidance of screens is not possible, but with proper habits and moderate use, children's eyesight can be protected," Dr Rao said.
