Eye infections are caused by damaging microorganisms, such as bacteria, fungi and viruses, that enter the eye, according to All About Vision. The surface of the eyes and the lining of the eyelids are subject to infections.
Pink eye, or conjunctivitis, is a common type of eye infection, notes All About Vision. This infection is highly contagious and is usually spread through young children in classroom environments. Pink eye has a viral and bacterial origin. Ocular herpes is another type of viral eye infection, which is caused by exposure to the Herpes simplex virus.
People who wear contact lenses are at a slightly higher risk for invasive parasites that irritate the eye and cause serious infections. Proper contact lens use and care is urged by All About Vision. To avoid eye infections, individuals should keep contact lenses clean and avoid wearing them while swimming.
If a household member has pink eye, that person's bedding and towels must be separated from the rest of the household, explains All About Vision. Everyone in close proximity should wash their hands often and avoid physical contact with the infected individual. Using anti-bacterial sprays and cleaners in public areas such as libraries and classrooms can also help prevent the spread of contagious eye infections.
