Meta fits its smart glasses with a bright LED that turns on while the cameras record, so bystanders know. Engadget's Karissa Bell bought several sticker kits sold as privacy accessories and found them "cheap and surprisingly effective". They work by not doing the obvious thing: rather than covering the LED outright, which trips a warning, a notched clear layer lets a sliver of peripheral light reach the sensor while a black sticker hides the LED from everyone else. Meta pushed a mandatory update that permanently disables the cameras if the light is physically broken, and these kits sidestep it because nothing is broken. One sold for $16.99 with a dozen stickers and a pair of tweezers.
This is the third pressure point on the same product in a week. An app that charges $3 to spot the glasses in a room reached the top of the App Store's paid chart, and Instagram banned filming strangers with them. None of it has dented sales: EssilorLuxottica told investors smart glasses revenue nearly doubled in the second quarter. The safeguard and the workaround are now a product category of their own, and the safeguard is losing.
