Dry Eye Syndrome
What Is It?
Dry eye syndrome occurs when there is an inadequate quantity or quality of tear production to moisten, protect and cleanse the eyes. Dry eye syndrome is one of the most common eye problems. And it becomes more common as people age because tear production can diminish as part of the aging process.
More women are affected than men. And the syndrome is more likely to flare up at times of hormonal change such as after menopause or during pregnancy or breastfeeding.
