Your Natural Tears
Eyes are lubricated by tears produced by tear glands located in your upper eyelids. Blinking spreads a film of tears over the surface of your eyes. The tears move to the inside region of the eye and through the tear drainage ducts into the nose and throat. Tears make your eyes feel cool, comfortable, refreshed and helps to prevent infection.
What causes Dry Eye Syndrome?
When the balance of tear production and tear loss is not maintained, dry spots appear on the eye’s surface and cause irritation.
Can Watery eyes be a symptom of Dry Eyes?
Ironically the tear production glands sometimes react to the dry, scratchy feeling by watering more than ever. These reflex tears do not relieve the dryness as they lack a natural component that is essential to lubricate the cornea properly.
Can Dry Eyes harm my eyes?
Yes. If left untreated severe Dry Eye Syndrome can damage tissue and possibly scar the cornea of the eye.
Common causes of Dry Eye Symptoms.
Environment—The list is virtually endless! Sunny, windy, dry conditions, air conditioning, dry climates, smoke, air pollution are just a few.
Contact lens wear—these could result in increased evaporation of tears which leads to irritation, increased protein deposits, infection and pain. Dry Eye Symptoms are the number one reason people stop wearing contact lenses.
The aging process—tear production gradually decreases with age. At age 65 the tear glands produce about 40% of the lubricating tears they produced at age 18.
Medications—tear production could be reduced if you take certain medications. These include decongestants, antihistamines and diuretics, beta blockers, sleeping pills, anti-depressants, pain relievers, alcohol, oral contraceptives.
Computer users—Computer and television users may also have dry eyes as a result of staring for hours without blinking regularly.
Diseases—these include Rheumatoid Arthritis, Diabetes,
Thyroid abnormalities, Asthma and Lupus.
Menopause and pregnancy—women are more prone to develop dry eyes after menopause and during pregnancy.
