Many things can cause eye infections, so it is important to determine the cause before you start to treat your infected eye.
The most common infection we see is conjunctivitis caused by an adenovirus (the common cold). There are other types of bacteria and viruses that can cause eye infections. Fungal infections are also seen, though they are not as common.
There are times when eye infections get better without any treatment, though you should still see your eye doctor to make sure you don’t need to do anything. Most of the time, we prescribe medications to place right in your eyes to get rid of the problem.
