I have not had this problem myself. My mother got pink eye often. she was diabetic, and totally paralyzed on her right side. do not know if she really had pink eye, or something like you have had. I was not educated enough to give her the best care maybe. I didn't have internet either though, so I accepted what the doctor called it.
I have the opposite eye problems. Too dry. I have to take restacin every day twice a day due to Sjogren's. Sjogren's dried everything up. at least it has done this with me.
I did have light sensitivity however, when I first started taking plaquenil, but it was a side effect of the meds, and it went away.
Hope your day will be good to you
