Cool idea...but how do you get energy to power the electronic contact lenses?

@Krisi: An integrated micro battery and/or energy harvester of course. Ambitious, I know!

Yeah, I know energy harvesting would be the best...but where do you put it? most harvesters require space, likely energy to be harvested is proportional to the volume of the harvester (or its surface)

Actually many innovations can be done on contact lenses its jusf one has to thinkover and keep on challengng.

Ben Krasnow sandwiched a coil between contact lenses and powered an LED while wearing it... in his GARAGE!

 

Check out the video, it is insane.

Induction, perhaps?

More SciFi to become reality

A logical step in technological evolution for me but my daughter pointed out the Scifi series Continuum where contact lenses are taken to another dimension. Thinking back to some older Scifi shows, they already implied the use of tablets, video phones and tricoders. Maybe we should take a closer look at what SciFi shows us now. This may be soon the next gadget of technology.

OK, the coil is in the lens now, I get that...where is the other coil and source of energy? (in a practical device)

Auto-focus contact lens

It seems that a much easier application would be to use a liquid lens and a distance sensor to produce a self focusing lens. The challenge, when driving, would be to avoid focusing on the automobile windshield and to focus on the road instead.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
