One of my future ideas was to have the detection trigger turning a bunch of IR LEDs on to do just this! I've only tested it a little bit against my phone camera (with around 5 850nm LEDs), but it didn't work super well (fairly bright but not enough to be useful). It did work much better in low-light though. My guess is modern cameras have better IR-cut filters, but like I mentioned I only tested against my phone and not the Ray-bans yet.

Have you thought about the potential eye/skin damage you would be causing with IR LEDS.

Potentially as much as none, because it's UV that does the damage?

		I guess IR can be harmful (IR lasers, military grade IR LEDs). But yes, likely not the consumer grade IR LED.
