I think you nailed it. Ball players, race car drivers get concussions all the time and none of them wear any special eye glasses.
Or just a ugly fashion statement.
My glasses are for astigmatism which is real bad even after cataract surgery on both eyes you only get a mono vision for a middle distance lens. I wear fashionable simple no line. Or blended lenses as they are called. Mine would be a coke bottle thickness if not for feather weight. And I buy the BEST ZEISS lenses, which has the widest middle distance field of any on the market. No box store crap for me.
My son played high school and college football. Concussions were all around him. There was never anything like these glasses.
And besides — the convoluted story about her concussion — stomach virus, dehydration, fainting in her house, blood clot, just sounds like BS. How the hell hard could she hit her head? And what did she hit? Steel? Bricks? Stones? How about Bubba blowing out his knee at Greg Norman’s “house.” WTF do these people do around the house? Everything is so weird with them. (Because they are pathological liars.)
