Dry eye -- also called dry eye syndrome or dry eye disease -- is a common condition that occurs when your eyes do not make enough tears or produce tears that evaporate too quickly. Symptoms of dry eye range from mild discomfort to blurry vision and extreme eye irritation. Often dry eye can be managed with over-the-counter treatments, but if symptoms are severe or do not get better, it’s best to see an eye doctor. Here, Kourtney Houser MD, a corneal specialist at Duke Health, answers common questions about dry eye and provides advice on when to see a doctor.
