I've been on it for 10 years with no problems. My eye doctor told me the drug was reformulated many years ago and it is an incredibly rare occurrence any more. He says the dangers are now over-hyped. Not taking meds, however, causes the disease to progress. It is a systematic illness. It has attacted my lungs and caused damage. Just make sure you make informed decisions and realize not taking a med your doctor prescribes can also have severe consequences. If you have questions about your eyes, call your eye doctor. Ask them. Ask them how many cases they have dealt with because of hydroxychloroquine. They will give you an honest answer but obviously, can't predict the future. Everything has risks, even taking a shower. Of the meds that could be coming your way, that is one of the most harmless. Now THAT is scary! Hope this helps some.
