thats a pair of Hobart welding goggles
, retrofitted with shade 14 50mm lenses (they come with shade 5 which is far too light for sun viewing).
coming soon, my optician said they can cut me my Rx onto 50mm circular plastic, and index mark them so I install them correctly
this should be good
actually, since taking that selfie, I've also shortened the bridge so they fit tighter to my nose and are parallel and not walleyed like in the pic.
and after the eclipse, I guess I could wear them to burning man!
