They do this generally while doing some kind of movement based activity, the kind of activity where you need to strap a camera on, not wear a set ofglasses.
Can you list activities that you're thinking of? Because a lot of active sports are compatible with "wearing glasses". Surfing, snowboarding, rock climbing, water skiing, mountain biking, etc.
Sure, scuba divers still need some specialized gear, but there's tons of room in the sports segment for this kind of product.

I would not say any of those are compatible with wearing fashion-style sunglasses. I've lost pairs of glasses paddleboarding and kayaking before. I'm a mountain biker as well and crashes can be violent, I wouldn't trust glasses to stay on your face. All of those sports require firm attachment for a device worth more than say $100.
