Jenga Glasses

A pair of eye glasses with ridiculously thick lenses which render any wearer, other that the glasses owner, almost blind.
Origin - a variation on the game of Jenga when players must don thick glasses when taking their turn thus distorting their vision and making the game more challenging - see Glasses Jenga

“Do you like my new glasses?”
“Wow, can you actually see through those? They’re proper Jenga Glasses!”

“The guy was so blind he actually needed Jenga Glasses”
