They are made from a material that reflects visible and/or infrared light and its lenses block the system that is used to measure the distance between your eyeballs avoiding to create a unique profile from your face. Many facial recognition cameras (not all) relies on infrared to search for patterns in human face and this glasses reflects IR. These glasses are one of the few tools that we can at least use to try protect our privacy against facial recognition.

They’re IR reflectors. Presumably only work on cameras with built in IR lighting, and only at night.
A more effective thing to do will be to add IR LEDs to a hat or something over/around your face.
Buy a pair , test them with the tech they claim it blocks and tell us how it goes.
Facial recognition does not need to use infrared in any way to work. Source: have trained many models
