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 in any of the components of a tear that are secreted by glands in and around the eye or an alteration of any of the layers of the tear film - lipid, aqueous or mucous layers. When this happens, the tear film may not properly coat the eye, leading to loss of moisture, increased dryness and discomfort.
