S.W.
My middle daughter has bad allergies...they are bad enough that sometimes they seem more like a cold. When the symptoms are severe enough, she gets allergic conjunctivitis...and form of pink eye. I took her to an allergist and with the proper medication, she rarely has to deal with pink eye anymore and her allergy symptoms are much, much better. The doctor gave me eye drops that I keep on hand. As soon as her eye or eyes start to itch and look at all pink, I put one drop in each eye and that takes care of it before it gets to be full blown pink eye.
