to seasonal allergic conjunctivitis (SAC). Patients
suffering from PAC typically report that symptoms
occur year-round but tend to exacerbate in the

fungal allergens are greatest). Patients with SAC (hay
fever) commonly report that symptoms occur in the
spring and summer months, with tree and grass
pollens being the most frequent offending agent.
