When viruses, bacteria, fungi, or parasites invade the eyes or surrounding areas, the result can be a variety of infections. Although they can be mild and heal well with no treatment, eye infections may also result in permanent vision loss. Optic nerve or retinal damage is often painless, so deteriorating vision requires emergency attention.

Washing hands frequently, using clean towels and tissues, disinfecting contact lenses, and laundering bedding can prevent many eye infections. If you do begin to experience symptoms, learning about the different kinds of infections can help you know what steps to take.

1. Conjunctivitis (Pink Eye)

A highly contagious inflammation of the tissue covering the whites of the eyes and inner eyelids, conjunctivitis is the most common eye infection. The pink or red eye is often itchy with a thick discharge, excessive tears, and a gritty feeling. Usually lasting about a week, viral conjunctivitis is common in adults and usually requires no treatment.

Bacterial conjunctivitis is more typically found in children and can be treated with antibiotic eye drops or ointment. It should show improvement within five days, although it could last significantly longer. Symptoms may be helped by cold compresses. Antihistamines and eye drops may help pink eye that is triggered by allergies.
