My shimmering issue was a one-time event - in the waiting room. My TSH at that time was 0.06, with slightly elevated T4/T3 numbers. Six months later, my TSH was 0.16 (just shy of the 0.20 minimum "normal").
Because of the levels being fairly close to "normal", short, brisk walks (2 city blocks), one to a few times per day... (81 replies)
... dots are white blood cells moving in the capillaries in front of the retina near the macula. There are no blood vessels on the retina in the very centre of your vision so you can't see them right in the centre.

My guess is that you were behind the wheel driving without taking a significant amount of time to rest your eyes and you experienced extreme eye strain from dry eyes. The other possible scenario is that you developed a migraine (you do not have to have a headache to experience a migraine) due to being overly tired. I actually just experienced one this morning....
