Recently, we have been seeing a lot of patients who say, “Doctor, I’m usually fine, but lately I’ve been experiencing particularly pronounced tearing in the wind.” There are even many parents of babies who are worried that their babies are suffering from lacrimal duct obstruction and come to the clinic. In fact, most people have tears in the winter, which is a normal physiological response to the cold, do not need to be too nervous. Under normal circumstances, some of the tears are evaporated and some flow into the nasal cavity through the tear dots, tear ducts and nasolacrimal ducts. In winter, due to cold air stimulation, the eyes reflexively secrete more tears, while the drainage of tears “sewer” contracted by the cold becomes thin, the drainage of tears is not sufficient, once the imbalance in and out, there will be the phenomenon of tears. The elderly due to the orbicularis oculi and lacrimal muscle relaxation, tear pump role is weakened or disappeared, more likely to see the wind flow of tears. You can wear windproof glasses when you go out, and perhaps the symptoms can be reduced.
