When I have my eyes examed in the hospital, my doctor says that abnormal tear secretion can cause unnatural tears, especially in winter, because the temperature is very low while our eyes can be easily affected by the cold wind.
Our eyes are very sensitive, however when the wind is breezing, it is easy to stimulate lacrimal gland, especially in gale weather, which will cause more tear.
Most of us have such phenomenon, sometimes if the sands are brought into your eyes when browing, it will also cause unconscious tear, thus I suggest you to wear goggles before going outside in gale weather and pay attention to eye health in daily life.
