Dry eye is a term used to describe a group of different diseases and conditions that result from inadequate wetting and lubrication of the eye.
Although millions of people experience it, dry eye is not always easy to diagnose; it can easily be mistaken for other conditions such as infections or allergies.
Believe it or not, excessive tearing caused by crying, cold weather, etc., can actually cause dry eye symptoms.
There are many different abnormalities that can cause dry eye, such as decreased tear production, excessive evaporation, blinking problems, etc. Many medications, such as antihistamines, can also contribute to dry eye.
