Watch this video about Sony (also Google & Samsung) creating special contact lenses that can record video and take pictures while you wear them:
This looks really cool, but I can tell there will be a few issues…
(1) There cannot be any (large, desirable amount of) storage on the contact itself, so it has to use bluetooth/wifi/RFID/some other tech like that to beam the data to a storage device, probably located on your person. The eyes are the most sensitive body part when it comes to the amount of radiation it can take (which is very little compared to larger, less sensitive body parts such as thighs/arms). These contacts would have to constantly beam information to a storage device 24/7, which would expose your eyes to a lot of radiation — possibly causing defects, reduced vision, and cancer.
(2) Not only that, but… hackers stealing your “eye video stream” while it beams to your storage device.
