Girls, hi! We went to the clinic today unfortunately, there were many people there, including coughing?‍? people who wanted to see an ophthalmologist, they waited for 40 minutes, a guy was sitting next to us too. Then the nurse gave us drops and said again in 15 minutes, then again. And this guy says to her "it seems like I have conjunctivitis"???‍♀️ I have two questions, after one drop the child already got tired unfortunately we waited for an hour, and I left, is it a big deal that she gave one drop? And second, can you calm me down, can conjunctivitis be contagious????????
