"Eye flu" is not a recognized medical term. However, it's possible that you might be referring to conjunctivitis, commonly known as "pink eye." Conjunctivitis is an inflammation of the conjunctiva, the clear tissue covering the white part of the eye and the inner surface of the eyelids. It can cause the eye to appear red or pink and may lead to symptoms such as itching, burning, tearing, and a discharge.
