I have seen only one legitimate use in the wild:

There is a gentleman who goes to shelters and tries to rehabilitate traumatized dogs. I think his channel is called “sitting with dogs” or something like that.

He recently switched to these glasses because it more easily allowed him to record what he was looking at without using his hands. Because excess hand movements could - and sometimes did - spook the dogs. It also allowed him to use both hands to do certain things, which IIRC proved to be safer in some instances.
