Eye Infections are eye ailments caused by bacterial, viral, or fungal agents. There are many different types of eye infections, with different causes and treatments. All parts of the eye are susceptible to infection.
Eye infections can affect one or both eyes, and can occur in people of all ages. Symptoms can include irritation, redness, discharge, and reduced vision. Treatment typically depends on the cause. Let’s go over the possible causes of eye infections now.
What Causes an Eye Infection?
Eye infections can affect any part of the eyes, from the eyelids to the cornea, and even the retina in the back of the eye. Eye infections are so common that most of us either have had an eye infection or know someone who has had one. Eye infections can be bacterial, viral, or fungal.
People who wear contact lenses are particularly susceptible to eye infections due to the decrease in oxygen reaching their corneas and due to bacterial or fungal buildup caused by failure to properly disinfect their contact lenses. Some common eye infections are pink eye, blepharitis, and trachoma. Trachoma, which is more common in poor countries, is easily spread and can lead to blindness.
Eye infections are usually self-limiting, and most resolve with minimal or no treatment. Occasionally, they don’t resolve quickly, and lead to more severe problems that require some type of medication for treatment. Not all eye infections are dangerous, but some require a doctor’s immediate attention. If you believe you have an eye infection, you should seek the advice of an eye-care professional.
