Medical Author: William C. Shiel Jr., MD, FACP, FACR
Dryness of the eyes can be a normal response to weather or medications. Dryness of the eyes can also result from temporary or chronic health conditions. The tears of the of eye come from the tear gland, called the lacrimal gland, which is located above the outer eye. Tears are composed of water, oil, and antibodies. The moisture from tears on the front of the eye, the cornea, is important to avoid damage of the cornea.
