Ivee been gettin white mucus plus itching in my eyes for the past two years.. mostly in right eye and im not sick. what could it possible be?

Allergies: It is impossible to tell for sure without an eye exam, but allergies are common and associated with itching and discharge.

Allergic conjuntivit: An itchy rash in the eyes that lasts 2 years is most likely to be due to allergy - either something in the environment or something you're applying.

Allergic disease: Symptoms are suggestive of an allergic type eye condition, but it could be an infectious eye condition. The only way to determine this is with a complete eye examination.
