The title image reminds me too much of Clockwork Orange to watch the full video - and I realize this is a proof of concept, but in hacker news nit picking style wouldn't the need for a feeder induction coil next to the eye mean you might as well wear glasses and have the LEDs mounted there?
You could probably put some of those 4.5mm inductive LEDs under your eyelid and the induction loop in a hat band?
