Enthusiast engineers often come up with unusual and amazing things. One of these appeared on Reddit a couple of months ago – glasses that turn off the light when you close your eyes and turn them on when you open them. Or rather, these are not glasses, but a kind of monocle, the sensors inside which read the position of the eyelids. The gadget looks like a rough prototype and is connected by wire to a physical light switch – the description indicates that such a device is useful for saving energy. It also shocks the user for fun.
The idea of this engineer can be useful for manufacturers of smart glasses (according to rumors, the same Apple has been developing such a gadget for several years, and Google has had Google Glass for a long time). It is hard to believe in tangible energy savings by turning off the light during blinking, which the author conceived, but the very idea of \u200b\u200bfixing the position of the user’s eyelids can come in handy. For example, this can be used to activate a smart glasses function with a double or triple blink.
