An eye infection occurs when a potentially harmful microorganism like a fungus, a virus, or bacteria invade your eyeball or the area surrounding your eye. The infection can affect the eyeball, the clear surface of the eye (cornea), or the eyelids.

Its obviously, bacteria cause bacterial infections, and viruses cause different viral infections. The treatments differ depending on whether you have a bacterial or viral infection.

Bacterial infections are often treated with antibiotics, which can kill the bacteria or stop it from multiplying. Antibiotics will not work for viral infections.

Instead, the symptoms of the virus are usually treated directly. There are some antiviral medicines that can stop the virus from reproducing. Certain vaccines can prevent viral infections from occurring in the first place, such as the vaccine for influenza.

Many of the common bacterial infections of the eye will readily clear up once you are prescribed an antibiotic or some other treatment like eye drops. Some of the more common viral eye infections may resolve on their own, but they may require antiviral eye drops or even steroids to reduce inflammation.
