Scam.
Also Lenses come in predetermined powers. Bought as a pair for a few bucks and cut out like keys from a blank. Sold for hundreds.
Look into luxotica. They own fucking everything.

I'm about to have my buddy 3d scan my head lol. He's gonna print like a dozen frames. I'll get lenses put in 1 by the optometrist then I can swap them to any other frame as I see fit. Fuck the system.
