Excessive tearing in cold weather, a common occurrence, results from the eyes’ natural defense mechanisms overreacting to low temperatures and wind. The eyes produce extra tears to protect the ocular surface from drying and to warm the cornea. This overproduction, combined with slower tear evaporation in cold air, leads to watery eyes. For instance, stepping out into a biting wind can trigger this reaction almost immediately.
Protecting eyes from the elements offers significant benefits beyond mere comfort. Reducing excessive tearing improves vision clarity, which is particularly important during activities like driving or winter sports. Furthermore, minimizing exposure to cold, dry air can help prevent dry eye symptoms that can arise from the constant cycle of tear overproduction and evaporation. Historically, people have used various methods to shield their eyes from the cold, from simple eye coverings to specialized eyewear.
