Five-ten years ago there was a thing for LED eyelashes - glued to your upper eyelid, super-fine wire running to a battery by your ear. I'm not sure how they worked electrically, but the fancier ones appeared to have individually addressable LEDs along the upper eyelid. I thought they looked cool.
Huh, cool, I completely missed that trend. From electronics point of view I'd assume they work the same as any other regular led strips, just miniaturized. Now I'm tempted to just buy some and the figure out an occasion to wear them
