Visual acuity is preserved in bacterial conjunctivitis as long as the cornea is intact, except for the expected mild blur secondary to the discharge and debris in the tear film. Some patients may inadvertently abrade their own corneas out of symptomatic frustration, leading to worse vision, even more discomfort, and increased morbidity. Rarely, topical anesthetic abuse can initiate or exacerbate this complication.
