It is incorrect to say that whether a baby is smart or not depends on its eyes. In fact, one of the most important factors in whether a child is smart or not is the degree of development of the child’s brain, and the higher the degree of development of the child’s brain, the smarter the child will be. The eye is actually a state when both eyes gaze at the same target, if there is a child with strabismus will occur, the phenomenon of deviation of the visual axis of any one eye, can be due to the two eyes of the monovision abnormality, or control of the eye movement nerve, muscle abnormality, or all kinds of mechanical constraints caused by the child’s one eye to gaze at the object of the other eye deviation, leading to the eyes have no eyes. At this time, parents may think that their children have intellectual developmental problems, which is totally incorrect. Strabismus is only an abnormality of eye position, and it is not related to whether the child is smart or not.
