Pay attention to whether the child’s eyes are too close to the book when reading and writing; whether both eyes are gazing at the same time when looking at things, whether one eye is gazing and the other is skewed; whether the child has the habit of looking at the TV or the blackboard with a tilted head; or whether the child is prone to looking at the wrong line and not concentrating. If you have the above conditions, you should go to the hospital for examination, which is an effective way to detect amblyopia at an early stage. From the principle of children’s eye care, it is necessary to routinely and regularly go to specialized hospitals and pediatric ophthalmology specialty clinics for children’s eye care checkups.
