Symptoms, types, and causes of eye infections
Eye infections and diseases can result when harmful microorganisms penetrate any part of the eyeball or the area nearby. These microorganisms can be fungi, bacteria, or viruses. The parts of the eye that can be infected are the clear part from the surface, called the cornea, and the thinnest layer that lines the inner eyelids (conjunctiva) and outer eye.
