Screen time has become an integral part of our daily lives, especially for children. From watching TV to playing video games and using smartphones, screens are everywhere. However, recent studies have shown that excessive screen time can lead to near-sightedness in children.
According to a study published in the Journal of the American Medical Association, children who spend more than two hours a day on screens are at a higher risk of developing near-sightedness, also known as myopia. This condition causes difficulty in seeing objects that are far away, and it has become increasingly common in children.
The study, which involved over 4,500 children aged 6 to 8, found that for every additional hour spent on screens, the risk of developing myopia increased by 30%. This is because screens emit blue light, which can damage the retina and lead to eye strain. Additionally, excessive screen time can also cause children to blink less, leading to dry eyes and further strain on the eyes.
Dr. David Granet, a pediatric ophthalmologist, explains that the eyes of children are still developing and are more susceptible to the effects of blue light. He also notes that children who spend more time outdoors have a lower risk of developing myopia, as natural light helps to counteract the effects of blue light.
So, what can parents do to prevent their children from developing near-sightedness? The American Academy of Pediatrics recommends limiting screen time to no more than two hours a day for children aged 2 to 5, and no more than one hour a day for children aged 6 and older. It is also important to take regular breaks from screens and encourage children to engage in outdoor activities.
In addition to limiting screen time, parents can also invest in blue light blocking glasses for their children. These glasses filter out blue light and can help reduce eye strain and the risk of myopia.
It is crucial for parents to be aware of the potential risks of excessive screen time and take necessary precautions to protect their children’s eyesight. As technology continues to advance and screens become more prevalent, it is important to find a balance between screen time and other activities to promote healthy eye development in children.
