Dry eye syndrome or keratoconjunctivitis is a common condition. Although it can be uncomfortable to endure, dry eye is also very treatable. In simple terms, dry eye develops due to a lack of lubrication on the front surface of the eyes, either because the body cannot make enough tears, or makes poor quality ones. If the eyes lack sufficient lubrication, they can become swollen, red, and irritated.

1. How Common is Dry Eye?

Dry eye syndrome is one of the major reasons people visit their optometrist. According to a 2012 poll, more than 26 million Americans over the age of 18 experience symptoms of the condition. Additionally, an estimated five million people over the age of 50 experience dry eye-related issues. Experts believe these numbers will increase as people spend more of their time in front of screens.
