Dry eyes and tears in the wind may be caused by the presence of dry eyes or narrow tear ducts or blocked tear ducts. Tears are produced by the lacrimal gland and are discharged through the tear ducts to the nasal or oral cavity and other organs. However, if the tear duct is narrowed or blocked, it will cause tearing, and if the narrowing of the tear duct is aggravated by wind and cold, it will make the tearing phenomenon more sensitive. At the same time, if there is a certain dry eye symptom, the eyes will compensate and irritate the flow of tears to make the tear glands discharge more, and excessive tears will flow out. Therefore, if it is dry and windy, which itself is the cause of excessive tear production, and at the same time encountering the narrowing of the tear duct will obviously lead to the generation of the tear phenomenon.
