If your baby has occasional eye pairs within 6 months of age, it can be normal. If the baby has a pair of eyes after 6 months of age, it is abnormal, and we should pay attention to the following two conditions: First, abnormal vision. Most of the pairs of eyes are caused by moderate hyperopia, so take your baby to the ophthalmology department for refractive error screening and early treatment with glasses or surgery, as well as early training related to amblyopia. Second, brain injury syndrome. Babies with high-risk factors before, during or after birth that damage the nerves associated with the eye and thus innervate the eye leading to crossed eyes are treated with eye surgery along with early rehabilitation.
