Dry eye is a condition in which a person doesn’t have enough quality tears to lubricate and nourish the eye. Tears are necessary for maintaining the health of the front surface of the eye and for providing clear vision. Dry eye syndrome affects millions of people around the world, especially in dryer environments. It is more common in women and can worsen with age. Dry eye can range from a mild condition to a debilitating vision-threatening condition.
Dry eye can be associated with autoimmune conditions like Rheumatoid Arthritis and Sjogren’s syndrome. Hormonal changes in menopausal women can induce dry eyes. Computer use can worsen symptoms because we all blink much less when we are concentrating on the computer or reading. Other causes of dry eye include contact lenses, seasonal/environmental allergies, heating, air-conditioning, air pollution, cigarette smoking, Bell’s palsy, and infections like ocular shingles and medications.
