Oh, you bring up the 2nd method that defeats facial recognition, and it is a similar exploit that attacks a weakness in the technology chain. Remember "Ed Hardy" that god awful fashion from around 2013 where clothing had graffitti, sequins, and flashing LEDs? You now love that fashion and bring it back, because those little flashing LEDs, if close to your face, and flashing at irregular intervals cause the nearby face to become silhouetted. The reason is the flash overwhelms the light sensor, causing the light aperture to adjust, but that adjustment is out of sync with those flashing LEDs. The LEDs and their irregular flash cause the lighting aperture to be constantly adjusting and never quite correct. You'll b seen by facial recognition, but the image quality will be nearly useless. Blinky LEDs on eyeglass frames are a perfect location, as well as the brim of a hat.
