Common Eye Infections
Eye Infections are eye ailments that are caused by bacterial, viral, or other microbiological agents. Some eye infections are common while others are rare. Contact lens wearers are at higher risk for eye infections due to the bacterial buildup from constantly wearing the lenses without proper disinfecting.
Eye infections usually require some type of medication for treatment so it is important to seek an eye care professional for advice on the type and treatment of the eye infection, keeping in mind that these infections can affect any part of the eye.
