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.
