I once thought I had pink eye, b/c my eyes were all gooey and kept clouding over. When the antibiotic eyedrop didn't help, I went to the eye doctor, and he said it was allergies! It was so weird b/c my eyes weren't itchy. But the antihistimine eyedrops did the trick. You can get OTC ones, but I've been prescribed Patanol and it is wonderful.
