Yeah, like this review says, its almost impossible to place the mirrors on the lense in order for it to see past your head. So depends on which type of shades you have.
CycleAware ViewPoint Super Tiny Sunglasses Bike Mirror
These spy glasses are like having eyes in the back of your head. With mirrors on the side of the inside lens you can discreetly see if anyone is tailing you.

You can get these view point mirrors that you can stick in any set of shades. not sure if they are any good though, nice idea if they work.
These already exist. Though they should be split-screen so you can still see in front too. No?
You can get them but unfortunately they are just gimmicky things to spy on your kids. Surprised this doesn’t exist for cyclists etc
