Your eyes can become infected by a variety of different viruses, fungi, and bacteria. Each contaminant causes different afflictions, but eye infections typically show signs of irritation or pain, redness or inflammation, fluid discharge, and reduced visual capabilities. Contaminants may infect one or both eyes, and may lead to loss of vision or blindness.  The most common eye infections are conjunctivitis, sty, and allergy-related infections. If you experience pain or reduced vision, see a doctor immediately. If your infection is mild, there are a number of home remedies that can reduce the symptoms of your eye infection.
