What Causes Dry Eye?

Dry eye can result from a number of causes, including both physical and environmental conditions. No matter the cause, the result is a reduction or alteration in any of the three components or layers of a tear – water, mucous and oil – secreted by glands in and around the eye. When this happens, the tear film may not properly coat the eye, leading to loss of moisture, increased dryness and discomfort.
