I see halos, sometimes rainbow halos, other times just regular halos, around lights and I have for several years. I'm under the care of an opthamologist who is following me as a glaucoma suspect. Nothing to do with plaquenil, from what I understand (although I did take plaquenil at one time). As others have already mentioned, I would get thee to an opthamologist---not a primary and not a rheumatologist. The good news is that if it is the beginning of glaucoma, it can be treated before major damage is done.
