What causes crossed eyes?

Strabismus is a common eye condition, usually caused by various factors. One common cause is poor development or abnormal function of the eye muscles, resulting in the inability of both eyes to focus on the same object simultaneously. In addition, strabismus may also be caused by genetic inheritance, eye injuries, or intracranial lesions. To prevent and treat strabismus, regular eye examinations are recommended for early detection and timely intervention. Treatment options include vision correction, eye muscle exercises, and surgery, with specific plans developed according to individual circumstances and medical advice.
