Conjunctivitis, popularly known as pink eye in the United States, is a contagious eye infection. Bacterial conjunctivitis is a conjunctival irritation that bacteria, viruses, or allergies can cause. It's a highly contagious disease that spreads quickly from one person to another by touching infected people's things, coughing, and sneezing. Gram-positive bacteria and gram-negative bacteria can both cause bacterial conjunctivitis. Some of the symptoms include reddening of the eyes, rolling tears, thick yellow discharge, itching, burning sensation, blurred vision, and increased sensitivity to light.
