With the change of modern lifestyle, more and more people tend to “sit” for leisure, children have less time to participate in outdoor activities, more and more time to sit in front of the TV, so the phenomenon of “tilted head and side vision” is also increasing. The so-called tilted head, that is, the child’s face turned to the right or left, head down or head up to watch TV; the so-called side view, the child’s eyes to the side or eyes up or down gaze. This phenomenon is mostly seen in preschoolers, but also in elementary school students. This phenomenon is caused by watching TV and the phenomenon of “side-gaze” is TV side-gaze. As children watch television for too long, excessive concentration, will unconsciously tilt the head to one side, eyes to the other side of the gaze, and over time will form a habitual action. If the position of the television set and the child’s head position is not proportional, the child is also prone to television lateralopia. If the TV screen is too low, the child’s head will be tilted too far forward when watching TV; if the TV screen is too high, the child’s head and neck will be tilted too far back. For this phenomenon, we suggest: preschool children should leave the TV screen after watching 20-30 minutes of TV each time; the sitting posture of watching TV should also be correct, and parents should check the position and height of the TV at home to see if it needs to be adjusted. Due to the effects of side vision, almost all children have varying degrees of astigmatism, and some children may also have refractive errors, such as myopia or hyperopia. Some children may also have refractive errors, such as myopia or hyperopia, which should be corrected by timely examination and appropriate glasses at a specialist hospital. If the child has the phenomenon of tilted head and side vision but no refractive error, you should try to watch less TV and correct bad eye habits without special treatment. As the child grows older, the phenomenon of lopsidedness can disappear.
