I wonder if people with these robo contacts could be manipulated by a hypno toad type creature / contact point.

A new generation of contact lenses that project images in front of the eyes is a step closer after successful animal trials, say scientists.
The technology could allow wearers to read floating texts and emails or augment their sight with computer-generated images, Terminator-syle.
Researchers at Washington University who are working on the device say early tests show it is safe and feasible.
But there are still wrinkles to iron out, like finding a good power source....
... Lead researcher Professor Babak Parviz said: "Our next goal is to incorporate some predetermined text in the contact lens."
He said his team had already overcome a major hurdle to this, which is getting the human eye to focus on an image generated on its surface.
Normally, we can only see objects clearly if they are held several centimetres away from the eye.
The scientists, working with colleagues at Aalto University in Finland, have now adapted the lenses to shorten the focal distance.
Building the end product was a challenge because materials used to make conventional contact lenses are delicate.
Manufacturing electrical circuits, however, involves inorganic materials, scorching temperatures and toxic chemicals. Researchers built the circuits from layers of metal only a few nanometres thick, about one thousandth the width of a human hair, and constructed light-emitting diodes measuring one third of a millimetre across.
