It is possible that cold weather can affect vision. When people are in a cold environment, their eyes will dry and itchy because that there will be a change in the consistency of the protective tear film covering the surface of the eyes. When the temperature is below 30 Celsius degrees, the oily cover of the eyeball becomes hard. Some parts of eyes will be left unprotected from wind or other pathogens. When the eyes are exposed to temperature of 34 Celsius degrees, the oily cover will block meibomian gland ducts and the meibum returns to original condition. In cold weather, it is important to prevent the tear film from evaporating quickly. This can be done by wearing goggles.
