Children watching TV sideways may be suffering from strabismus or amblyopia. If parents find that the child side-eye watching TV, exclude the case of intentional, must pay attention to, go to the hospital in time for relevant examination, exclude intraocular and intracranial substantive lesions. If substantial lesions are ruled out, we should pay attention to the observation that the child’s side-eye TV watching may just be a habit, and correct the child’s bad posture and habits through active guidance. If the child has been looking at the TV and other things with the side of the eye, it may be that the eye is not well developed, long time looking at things with the side of the eye, it will form a strabismus. If left untreated, it will affect the development of vision and form refractive error or amblyopia, which will affect both vision and the aesthetics of the child’s eyes. If you find that your child is looking at the TV with his/her eyes sideways, you should go to the hospital in time to find out the cause and follow the doctor’s instructions to correct or treat the problem.
