Step-by-step explanation:
The most likely diagnosis for a 14-year-old male with a red, irritated right eye and eyelids that were "stuck together" is conjunctivitis, also known as pinkeye. Conjunctivitis is an inflammation of the conjunctiva, which is the thin, clear tissue that lines the whites of the eyes and the inner surface of the eyelids. It can be caused by bacteria or viruses, and symptoms may include redness, irritation, discharge, and a gritty sensation in the eye. The condition is contagious and can be spread through contact with eye discharge.
