Parents should take their children for an eye exam every two to three months to detect eye problems in a timely manner. It is also important to observe the child’s behavior. If you find that the child likes to watch TV close, nystagmus, abnormal head position, squinting when looking at things, etc., you should pay attention to it in time. If there is a family history of eye disease, the child should be examined before the age of 1. If there is a family history of cataract, the child should pay more attention to the early symptoms of the newborn to achieve early detection of congenital cataract.
