Hi, I saw your thread Anyone get blurry vision when they eat higher carb items like white rice? . I have the same thing happen to me and the same conditions you listed. I have been tested for diabetes ,my fasting results were in the 80s too and I also had a low TSH recently, but T3 and T4 were normal. I was told I had hypothyroidism and given prescription of Methimazole,low dose of 15.I tell my doctor ,over and over if I eat certain things I get temp blurry vision and she looks at me like I just said I'm from mars. I was wondering if you ever figured out why you get blurry vision.
