The team says that children tend to hold the smartphones too close to their faces, about 12 inches.
In each 12 children that were treated having the eye condition, 9 of them had gotten it due to the usage of a smartphone.
“Children showing signs of deviated eyes should consult a doctor immediately,” they added.
