Most pinkeye is viral in origin for a normal healthy adult.
It typically is caused by a type of cold virus
and may last for up to 4 weeks. Supportive care
includes cold compresses and artificial tears
, such as theratears, genteal, or systane. Avoid contact with others, and avoid sharing towels or pillows, since this is highly contagious. If your eye
does not improve in 2-4 weeks, seek help.
