Kinda cool, wonder how much these (http://www.core77.com/challenge/humanpower/pages/8desc.htm) are going to end up costing. Might get me a pair.

Blink powered? I'd love to see how that works.

The Night-Vision Contacts (NVC) uses a three-layered technology very similar to plasma screen televisions that allows for their thin design. To achieve the necessary electric charge to carry out the amplification of light a thin layer of neodymium-iron-boron (NdFeB) gel is applied to the outer eyelid. NdFeB is the strongest rare earth magnet that exists today and provides the magnetic field necessary to produce an electic charge on the surface of the contact lens. When a person blinks, the NdFeB layer charges the ferro-magnetic surface of the contact lens that is now excited with charged particles. Ambient light photons and some infrared light photons collide with the charged surface that sends charged particles into the thin plasma layer of the contact lens. These charged particles and light photons collide with electrons within the plasma layer. The electrons, in the collision, are forced to a higher atomic orbit. The electrons quickly return to their natural orbit and in doing so release ultra-violet light photons. The UV photons then pass into a phosphor screen and are converted into visible light.what happens when you walk into a bright room with them on?

Don't blink :D
I guess if they add a layer that stops too bright stuff to go through, problem solved.

I would like to note that we are looking at something for a design contest. It's a concept, far from being reality. Neat concept, though.

Well, then close them but don't open them. That way you won't get any light in. Bet you'll probably find something wrong with this solution as well.

Here is another thought:

We need lenses that are see through! So that we can see even when we are asleep! :p

There are some crazy products out there... just do a search for solar-powered flashlights if you think I'm kidding.

This one came up on Popular Science once....in one of their design challenges..

Not saying you are but..
Most people incorrectly assume that solar-powered means that the sun is directly powering the device. While this is true in a few cases for the most part it is not. The standard method is to use the soal panels to charge batteries which will store the device until it is needed. This method also helps to provide a constant voltage output.

You didn't pay attention in physics class right?
You can't produce a blinding light with the energy of a blink. That's like powering a 2000W searchlight with a button cell battery.
So there is no need for a pretective layer.

You don't

Not today, we had a Maths exam instead.
I soupouse it makes sense. But the lights are going to be strong anyway, so it may even protect you from the external light sources.

Silliness!

When you turn the lights on, this technology enables the user to see through light clothes! Imagine the applications! Perverts everywhere are already willing to hand over their life savings for this thing.
