One eye itchy watery is a common symptom of eye irritation caused by allergies, dryness, infections, or environmental factors. It occurs when the eye's surface becomes inflamed, triggering excessive tearing and itching.
The eye produces tears to lubricate and protect itself. When irritated, the eye releases histamines, causing blood vessels to dilate and the eye to become red, itchy, and watery. This response is similar to how the body reacts to allergens or infections elsewhere.
