Persons with pink eye have mild irritation of the eye and may be sensitive to light. There is excessive tearing. Vision remains normal. The whites of the eye (conjunctiva) is red. There may be swelling of the eyelid. If it is caused because of allergy, the eye usually itches. The discharge from the eye varies with the cause of the condition. It is watery when caused by a foreign body or air pollution. Allergic reactions cause watery or stringy, mucous-like discharge. Bacterial or viral infections cause the discharge to be like pus. Bacterial infections usually cause crusting of the eyelids, especially on awakening, and often spread from one eye to the other. |
