What are some common eye infections?
Some common eye infections include:
- Conjunctivitis: Commonly known as “pinkeye,” it’s the infection of the conjunctiva. Beside bacteria or viruses, pinkeye may also be caused by an allergic reaction or irritants. It can give a pink shade to the eye as the blood vessels beneath the white of the eye (sclera) dilate in response to inflammation.
- Keratitis is an inflammation of the cornea caused by bacteria, viruses, or waterborne parasites. It is common in people using contact lenses.
- Stye occurs as a painful, red bump under the eyelid or at the base of the eyelashes. Bacteria infect the oil glands in the eyelid or eyelashes to produce a stye. Styes, sometimes spelled “sty,” are largely harmless and not contagious.
