Dry Eye Causes
When the body cannot make enough tears to protect the surface of the eye, you may develop eye infections, inflammation, or corneal ulcers. If your tears are of poor quality and evaporate quickly, this can also cause dry eyes. Dry eyes lead to a variety of symptoms that affect both comfort and vision.
An arid environment and prolonged reading or computer work can often cause the tear film to evaporate. Dry eyes can also be caused by hormonal changes, allergies, auto-immune diseases, eye surgery, contact lens wear, and eye infections. Drugs like oral antihistamines, antidepressants, or hormone replacement therapy can also lead to dry eye symptoms. Other environmental factors, such as exposure to cigarette smoke or chemicals, can also stimulate dry eye symptoms.
