Have you ever seen those weird glasses before?
Only once or twice. Generally, you get to this degree of vision correction...if you’ve got a permanent blurry vision issue. There’s some exercise process for you to ‘rebalance’ your vision when you get to these glasses, and they only serve for a period of time (like a year). My hunch is that she had some mini-stroke, and is using the trip-and-fell accident to explain things. The fact that she really cancelled out all public appearances for six months after the episode....leads me to think she’s had a pretty long extended recovery period. I doubt if she’s one-hundred percent, and a campaign episode (especially a full-year on the road)...will likely result in another stroke. She’s got someone in her mind....to help...and it won’t be the Obama choice for the Democrats.
My daughter has a brain injury and she has prisms on her glasses. They are to correct double and triple vision in the lower field so she needs them for reading while looking down. Generally, they are to help with peripheral vision. The prisms are added to her regular glasses. You can actually see them if you are looking closely.
