Cover Lightlane recently, a device that can project a bike lane for cyclists. This improves safety in cycling, like the new Nike post.
Nike post the special glasses are designed to increase peripheral vision on each side by 25 percent. I guess these are better than the mirror I see in some types of motorcycle helmets.
I do not think the mirrors are involved in making the subsequent work. These goggles use Fresnel lenses, which are the same aperture and short focal length wide type used by the headlights. We could probably see what is behind you in some sort of curvy fashion, I suppose.
