Do you have scratchy or itchy eyes? Does the sun or bright light make your eyes extra sensitive? Are you thinking about switching to glasses because contacts have become uncomfortable? You may have chalked up your eye troubles to allergies or changes in the weather. However, persistent eye irritation may be the sign of underlying disease, specifically dry eye.
There are a variety of causes (like allergies, irritation by contact lenses, etc.) and symptom levels to consider when exploring eyedrops to treat your dry eye.
