What is dry eye?
Dry eye syndrome — also called dry eye disease (DED) — is one of the most common eye conditions worldwide and a primary reason for visits to the optometrist. When the natural moisture in your eyes is reduced by factors such as weather, hormones, and certain medications, it can cause irritation often resulting in a burning or itching sensation. Sometimes it feels as though there’s a foreign object in your eye and for some, dry eyes can even cause excessive tearing, as your eyes try to overcompensate for their lack of protective tears. Prolonged, untreated dry eyes can lead to blurred vision as well.
