oh yeah... the eye doctor. masks fogging up the lenses on their equipment so you can't get an accurate reading. Then they say, oh, it's OK to pull your mask down from your nose, but be sure to keep it covering your mouth and chin! Just for a couple minutes while we check your prescription. What the heck is running through their minds, I wonder? Can we trust their judgment on medical advice since they don't grasp that this is nonsensical?
