I started to find that my sight was getting blurred if I focused on something for a while a couple of months after my partial thyriodectomy. I'm now on 50mg 1 day and 75mg the next. I had my sight checked last yr (pre meds) and its just off perfect ( 0.25 on each eye). Optician says he can give me glasses but I don't really need them. My eyes feel dry and a bit gritty but still produce tears. Think I'm becoming a hypochondriac!
