Pink eye or conjunctivitis may contain bacteria that can last about 2-8 hours on surfaces. Conjunctivitis is a highly contagious, uncomfortable infection of the eye’s conjunctiva layer. Although it is not painful or serious, it can be a nuisance. Thus, you should not share glasses, toys, pillows, tissues, and so on because of the length of time the bacteria live on surfaces. Pink eye that is caused by a virus can last 2-3 weeks as the virus can live on surfaces for several days. Ensure that people around you wash hands constantly and you can also disinfect surfaces like keyboards, phones, remote controls, and others regularly.
