What is the common name for conjunctivitis?

The common name for conjunctivitis is "Pink Eye." This term is widely recognized and used by the general public to refer to the inflammation of the conjunctiva, which is the thin membrane lining the eyelids and covering the white part of the eyeball. The condition is characterized by redness, irritation, and discharge, giving the eye a pink appearance, which is how it got its common name.

"Pink Eye" can be caused by various factors, including bacterial or viral infections, allergens, and irritants. The use of this terminology makes it easier for people to identify and communicate about the condition, especially when seeking medical advice or discussing symptoms.

The other terms provided do not accurately describe conjunctivitis. "Eye infection" is a broad term that could refer to any infection in the eye, not just conjunctivitis. "Red Eye Syndrome" is not a commonly accepted name for conjunctivitis and can also refer to other conditions that cause redness in the eye. "Contact Dermatitis" is a skin condition caused by a reaction to allergens or irritants, typically affecting the skin around the eyes but not the conjunctiva itself. Therefore, Pink Eye is the most accurate and recognized common name for the condition.
