What Are Eye Parasites?

Eye parasites are organisms or creatures like worms, protozoa or larvae that infect sections of the eye. They can involve the surface (such as the conjunctiva) or the internal organs such as the retina. Other times the parasites can be introduced to the body via food, water or insect bites and then spread to the eye via the blood. Such infections are different in their severity; some might cause insignificant irritation and others might lead to irreversible harm to sight.
