What is pink eye?
Pink eye is what people use to describe conjunctiva inflammation or conjunctivitis. A thin layer, called the conjunctiva, lines the white part of the eye and inside of the eyelid to help keep our eyelids moist, according to the CDC. When something irritates the eye or disrupts the conjunctiva, you’ll have pink eye symptoms including eye reddening in the whites of the eyes, itching, burning, and extra tears.
What causes pink eye?
A few causes of pink eye include viruses, bacteria, and allergens, per the CDC. Still, anything from chemicals to contact lens water could cause pink eye, too. Finding the root cause of pink eye is tricky since some symptoms are the same no matter their cause. Some contagious viruses can cause pink eye, but that’s not always the case. If you have pink eye but no fever or other symptoms, it could be OK to go back to school or work, the CDC says. If the eye redness isn’t spread throughout the entire eye, it could be subconjunctival hemorrhages, instead. This is what it could mean if you have a red spot on your eye.
