Why Are Your Eyes Dry?
A feeling of dry eyes can happen at any age. The older we get, the more likely dry eyes become. Tens of millions of Americans have some degree of dry eye symptoms, with nearly half being age 50 or older. Of those, more than three million are women. Dry eyes are a common source of discomfort. They can also be a symptom of a more serious problem that can lead to damage on the surface of the eye if left untreated.
Our eyes are naturally kept moist by a thin layer of tears which are necessary for good vision. These tears consist of three parts: an oily or lipid layer, a watery layer, and a mucus layer. The ratio between these parts is critical to maintaining the best consistency in our tears. Your eyes may feel dry if you are not producing enough tears, or if your tears are the wrong consistency and evaporate too quickly. A variety of other factors can contribute to the feeling that your eyes are dry:

I suffer from DES. I never realized my symptoms were DES until my eye doctor diagnosed me this summer. The symptoms can be easily explained away. Presently, due to health issues, I had 10 different prescriptions that I used daily or a couple of times a week. I researched all 10 medications and found the 9 of the 10 list dry mouth or dry eyes as a side effect. Remember any medication that will caused dry mouth can also dry your eyes.
I treat my dry eyes with eye drops and an eye ointment that my doctor recommended.
