Drinking milk cannot improve vision, but drinking milk is good for maintaining the healthy state of the eye. From a nutritional point of view, milk is rich in minerals, and a large number of trace elements such as calcium, phosphorus, iron, zinc and copper, which are essential components of the eye, but do not improve the patient’s vision. If you want to improve your vision, you must first understand the refractive status of the patient to see if there is refractive error, including myopia, hyperopia, astigmatism, and if there is amblyopia, what the cause of amblyopia is, and you need to treat accordingly according to the cause.
