BF and I buy a wading pool for the backyard during these hot months... fill it up, put a little salt in it and start swimming... a few days later, BF gets a case of pink eye. As an adult, my only case of pink eye was when I had an STD several years ago, so I got concerned. Then a few days after that, Roommate finds out that he has chlamydia. He has been in the pool a good deal as well. There is no chlorine in the pool.
So I get to doing some research, and find out that Inclusion Conjunctivitis
is cause by the Chlamydia bacteria and can be caught indirectly by underchlorinated pools. I believe that BF didn't get pink eye, but rather this Conjunctivitis
