Optician here from planet Earth... SO COOL TO SEE GLASSES I'VE WORKED WITH IN SPACE!!!
No, I didn't literally work with the astronaut's personal frames, but I have done a lot for my own patients! I even wear them myself!
If you have a curious mind like I do, and love observing even the tiniest details, you may have been wondering what glasses they are wearing up there in space...

The brand is called Silhouette, they're known for being super lightweight and having customizable lens shapes and designs. I have a pair myself and they're so cool they might be my favorite pair now after watching the crew throughout the mission..

It looks like both Commander Reid Wiseman and Mission Specialist Christina Koch are wearing the Titan Next Generation frame with a rectangular and rounded lens shape. And although I believe the frame is discontinued I have still seen it and worked with it before- Pilot Victor Glover appears to be wearing Purist frames, also with a rectangular lens.
My personal frames are below. I wear The Dawn frames with a teardrop lens shape, tinted with a Blue 1 to Rose 1 gradient for style points.
My manager was teasing me the other day being like "well if you're obsessed with space you picked the wrong field to work in" and I was like
"no you know what, glasses are a medical device, and some astronauts wear glasses.” Plus I forgot to mention lens coatings and technology for windows and cameras, much of which were invented by NASA themselves!
My adhd superpowers completely owned my manager. And if ever any of the Artemis II crew needs their glasses adjusted, repaired, or even cleaned, I'd be happy and honored to do so.
