“Dry Eye” Syndrome
Tears keep the eye moist, wash out dust and debris, and are essential to good eye health. Without this lubrication, the eyes become irritated and feel dry and scratchy. Dry eye, a chronic condition that tends to become worse over time, causes blurred and fluctuating vision.
Evaporative Dry Eye, the most common form of this problem, is caused by the dysfunction of glands that produce the oil responsible for preventing tears from evaporating too quickly.
What’s with all the tears?
Strangely enough, the irritating symptoms of “dry eye” can cause the eyes to water excessively. These tears are ineffective because they don’t contain one or more of the components needed to relieve the irritation.
