Justin Bieber had a doctor’s note to get him out of the Billboard Music Awards on Sunday night. The singer didn’t share a formal diagnosis, but he did share photos via Instagram featuring his conjunctivitis.
Commonly called pink eye, the infection can be viral or bacterial and results in a swelling of the conjunctiva, the mucous membrane that lines the inside of the eye. Irritants like pollution, smoke, pool chlorine and contact lenses could all cause the issue, as could sexually transmitted diseases in rare cases.
