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.
