Question
There are many reasons for children to blink, and as you described, it is often considered a reflexive blinking brought on by watching television. The fast-changing images on television can cause the visual center to become overly excited after prolonged viewing, leading to excessive blinking, which is also a kind of reflexive defensive action. Experiments have confirmed that watching television for 30-50 minutes has no significant adverse effect on a child’s eyesight, but if it exceeds 2 hours, more than 60% of children may experience varying degrees of vision decline, with increased eye fatigue. Although eye fatigue can be completely restored after rest, repeated episodes can harm the eyes.
Answer
It is advisable to have the child see an ophthalmologist to rule out eye diseases. In daily life, enhance attention and education on eye hygiene. Pay more attention to when children frequently blink and take precautions if there are irritants. It is recommended to keep a distance of 2-3 meters between the television screen and the eyes, and the room should have appropriate lighting. At the same time, psychological treatment should not be overlooked. If parents scold the child, it may cause psychological stress, leading to exacerbation of symptoms. Therefore, parents should be patient when persuading children to watch less or no television, and encourage them to: not watch television for long periods; not have a poor diet; engage in more outdoor activities.
