I used to have some glasses (spectacle) frames made out of the stuff when I was a teenager and I loved them: they wouldn't get broken when my dog would bash me in the face and I would use them like a fidget spinner, folding them in half at the nose piece. The nose piece would get warm when it bent and I found that, if I conducted the heat away with my fingers, it would then get cold when I released them -- bit like what a fridge does with its pressurised liquid. I've never seen glasses made out of them since.

I assumed Flexon glasses frames are made from some form of Nitinol? They just say "memory titanium" in their marketing, which is pretty much what Nitinol is. My dad had several frames of these, they behaved in that same heating/cooling way you mentioned. https://www.flexon.com/ https://www.flexon.com/

  I thought flexon was just very springy metal, not nitinol. Nitinol is not very rigid, it bends easily. And even though it snaps back when heated, it's not perfect -- I've got a few toys made of the stuff and after a while they get damaged and don't return perfectly to the original shape.

    Searching "Flexon" on Wikipedia redirects to Nitinol. This article claims its the same stuff, just a specific alloy: https://www.pressrelease.com/news/myeyewear2go-com-eyeglass-frames-with-flexon-for-durability-and-style-19583439 https://www.pressrelease.com/news/myeyewear2go-com-eyeglass-... The Beta Group, who claims to have started Flexon, says "Beta advanced the technology of Nitinol with its pioneering Flexon Ophthalmic Eyewear." https://www.betagroupllc.com/wrought-nitinol/ https://www.betagroupllc.com/wrought-nitinol/ Sounds pretty legit to me unless I see something else saying otherwise. I think they just stress the titanium of it as a lot of consumers probably think of titanium as a "space age" futuristic metal that they make space ships and the SR-71 and Lt. Dan's legs out of. Saying its made of Nitinol means nothing to a lot of average consumers.
