There is new smart contact lens with an integrated camera. The camera would be very small and sit near the edge of the contact lens so that it doesn’t obscure your vision. By virtue of being part of the contact lens, the camera would naturally follow your gaze, allowing for a huge range of awesome applications, early warning systems (the camera spots a hazard before your brain does), facial recognition, and superhuman powers (telescopic and infrared/night vision).

This new smart contact lens would have a tiny CMOS camera sensor just below your pupil, control circuit, and some method of receiving power wirelessly. Because an imaging sensor, by definition, has to absorb light, it wouldn’t be transparent — but it could probably be color matched to your iris, so that your eyes don’t look too freaky.
It also allows the camera to record and let someone else
look through your eye camera, who is at an offsite location.
