Question 1: What is Dry Eye?
Answer: Dry eye is a broad term describes abnormalities in the tear film. Other common terms for dry eye syndrome include chronic dry eye, dry eye syndrome, dry eye disease and keratoconjunctivitis sicca.
Dry eye doesn’t necessarily mean that your eyes are dry. In fact, many people find that they suffer from dry eyes yet experience watery eyes. Dry eye actually means that there is something wrong with your tear film. The tear film is a complex combination of different layers, which include water, oil and mucus. Each of the three layers in typical tear films come from different sources, therefore disruption to any of these sources can affect lubrication and lead to dry eye.
