Tear Quality

If the oil glands don’t produce enough oil in the eyes, the tears may evaporate at a quick pace resulting in dry eyes. If not enough water is present in the eyes, the oil and mucus layers can touch and cause a stringy discharge. Water that is present in the eyes is needed for cleansing and washing away particles and other foreign objects. The mucus spreads the tears evenly throughout the surface of the eyes. If not enough mucus is present then dry spots can form on the surface of the eye.

Drugs used to treat high blood pressure, antihistamines, and decongestants often dry out the mucus membranes in the body. Hormone replacement therapy, antidepressants, and certain acne medications may also cause dry eyes.
