Silverlioness, I had the same problem with plaquenil and vision. For me the efeect on my eyes became permanent. My right eye appears to have a cloud floating around in it. I can actually see it move and the opthamologist told me that the eye is filled with a jelly like substance and mine has a small gray matter in it. This is causing the blurred vision. This all started with the plaguenil and it has been 8 years ago. When the "cloud" is not directly in the center I can see very well.
