My boyfriend and i keep getting pink eye. we've had it 5 times in one year, each time a few months apart. why do we keep getting it?

Truly infection??: Many times when the eye gets repeatably "pink" it may not be infectious. The most common cause for multiple episodes of "pink" eye with "goopy" tears is an allergic reaction. Some indolent infections (ie chlamydia) of lid problems (blepharitis) can give a "pink eye. Get an ophthalmologic evaluation. If you already have, get a second opinion.

Get checked: It is possible that the two of you have chlamydial conjunctivitis. You should get checked to make sure. If so, it is curable.

Don't touch eyes: New exposure vs. Reinfection. If new exposure, then you go someplace where someone with pink eye has just touched something. You also touch that item, and then touch or rub your own eye. If you don't touch your eye at all and always wash your hands, you can avoid 99% of pink eye. Clean everything in the house, especially pillow cases, sheets and towels. Use bleach to clean.
