There are several possible causes for eye tearing in the presence of wind. The most common cause is dryness of the eye surface or increased sensitivity of the cornea, which can lead to compensatory tearing after wind irritation. If the cornea is mildly damaged, it may also be irritated by the wind, resulting in compensatory tearing. The blockage or narrowing of the tear duct causes tears to drain out, especially in wind and cold, which will make the tear duct even narrower, so that excessive tears will not drain out and flow out, resulting in the phenomenon of tears in the wind. In this case, it is necessary to go to the hospital for examination to rule out corneal lesions and tear duct obstruction, and then you can use sodium vitreous acid drops for alternative relief treatment. The cause can usually be found and the symptoms can be relieved.
