Exposure to viral, bacterial, fungal or parasitic infections can cause eyes to become red, swollen and watery. Here is everything you need to know about eye infections.
What are Eye Infections?
Eye infections are eye conditions caused by microbiological agents such as viruses and bacteria that may cause your eyes to become red and swollen.
Types of Eye Infections
Conjunctivitis (pink or red eye) is the most common type of eye infection. It is an inflammation of the conjunctiva and the inner surface of the eyelids, usually due to a viral or bacterial infection. Sometimes, conjunctivitis can also be due to an underlying allergic condition.
A stye is another common problem that happens when an infection occurs in the hair follicle of your eyelashes. A stye normally looks like a small pus-filled boil or a pimple. If the infection of your eyelid is more severe, the condition is known as preseptal cellulitis , or an eyelid infection.
Keratitis is a serious infection of the cornea that can lead to scarring and vision loss. Improper contact lens care increases the risk of this condition.
