I wrote a message two months ago, about not only experiencing myopia but hyperopia after a year of experimentation with high-dose iodine, it happens. I literally went from perfect 20/20 to fuzzy double-vision and trouble quickly focusing on objects near and far.
Anyway, liposomal vitamin C greatly intensified the problem after a long break from iodine, while SOD eyedrops cleared the problem best for me. Probably the perfect anecdote from some suffering from the stress of PRK surgery. Although, in my case, I personally suspect mercury oxidation reached the protective barrier of my eyes. Good luck.
