⚡️Ray-Ban Meta Mirror sunglasses have a built-in LED light that indicates when you're filming or taking pictures.
🕶️The Snapchat Spectacles also have a filming light, but you can cover it with a sticker or tape to film in incognito mode.
🌑Some sunglasses use an algorithm to compare the light between the camera and a light sensor, allowing you to film without the LED light being visible.
🎥You can block the capture LED on sunglasses with a tape or your hand, and then start filming in incognito mode.
✋Covering the LED light on sunglasses with a finger can sometimes allow light to enter from certain angles, making the LED light less visible.
