I think IR lights on glasses can blind cameras, and there are also infrared-blocking glasses that also reflect IR light from cameras back at them. So yes, adding lights or reflectors can be effective.
But we shouldn't even have to consider these workarounds to maintain our privacy and security. And even if we start wearing these glasses or fooling the systems, governments will outlaw the use of such circumventing tech.
Our reaction to this needs to be "we will not allow this tech to be used against us, period." Ban it for law enforcement, ban it for commerce, ban it in airports and schools.
