Did someone wearing Meta Glasses film you today? Are you sure?

People say they've been secretly filmed in their own homes, at concerts and at work. Are the wildly popular smartglasses the final nail in the coffin of personal privacy?

I've had one person who told me that their intentions were creepy," a man tells me over a video call, on condition of anonymity. He's based in Los Angeles, and while we speak, he eats what appears to be tuna directly out of the can. He said: I go to strip clubs, and I want to record the strippers ... Normally I put my phone in my chest pocket, but the glasses are more convenient.'"

The man I'm talking to runs a business called Ghost Metas. He's one of hundreds of vendors, easily discoverable online, who specialise in disabling the flashing LED light embedded in Meta's smartglasses that blinks when wearers capture photos, videos and audio. After Ghost Metas disables the LED, it's impossible for someone to know they're being filmed.
