Belgian Researchers Build LCD Contact Lenses 98
First time accepted submitter nickvad writes "The Belgian Centre for Microsystems Technology has built a spherical LCD display in a contact lens. The technology is groundbreaking and holds a wide range of applications from medical to cosmetic applications and more. The LCD technology has the potential to be used as a productivity or a social tool, paving the way for futuristic technological innovations like Google Glass."

Should be easier than that. Set up multiple concentric focus zones -- we've got contacts like that already for "bifocal" use -- and dynamically black out all zones but the one you want to use. It wouldn't work especially well in bright light, though, where your pupil is contracted, because you'd only be "seeing through" the central zone anyhow.

They are floating at different depths near the retina, which is why some seem higher contrast than others as the ones closer to the retina cast a sharper shadow while those further away are blurred.
Think in terms of a viscous layer near the retina that gets accelerated in the direction you move your eye, then continues with a bit of momentum after the eye slows down or changes direction again. Try looking at a white ceiling while flat on your back, and try to play with one obvious floater for a while. If

Re: (Score:1)
It is possible to have a display on your cornea that can show images you can focus on. However, it would work differently than other displays.
Once light is at your cornea, a pixel corresponds to a direction instead of a location. That is, for far away objects, all the rays coming from one point (location) enter your cornea as rays traveling in the same direction; it doesn't matter where they enter. For objects that are closer than "very far away", they produce a bundle of rays that are slightly diverging
Re: (Score:1)
Thus for a display on your cornea to work, it has to be able to send out distinct light ray bundles in different directions, with each direction corresponding to a different logical pixel that you'd perceive spatially.
Figure out how to actually do that, and the world will beat a path to your door.

about the best this could be useful as, is as a flash protection optical device. Couple a thin film photocell to the LCD layer, so that a bright light automatically powers the LCD and dims the light that reaches the eye. That way it wouldn't need all that data bus hanging off of it.
For an image display? Useless. The focal distance is way too close for the human eye. The resolution sucks balls. Displaying an image would require a data bus, and I don't want that crap irritating my eyeballs by hanging out plastic ribbon cables.

No way. I took a welding class in college, and one day the instructor came in wearing a red and white stripped t shirt, and underneath were red and white stripes on his skin -- the rays from the arc welder had "sunburned" through the white stripes on his shirt.
Your eyes can get sunburned. Even worse, if a hot spark hits your eyeball, you're blind in that eye forever. Goggles and hoods are for more than just protecting your eyes from rays.

Instead of displaying an image the traditional way, it could simply be used as a prismatic refractor to alter incoming light to produce the 'perception' of having a distant image.
Eg, your eye's muscles focus "far away", because that is where the image would resolve from the controlled refraction done inside the lens.
This would be comfortable, but images would never appear opaque. (Relies on bright ambient light, and defraction of incoming light. Shadowy, shimmery outlines with candy pastel colors would be a

Of course you couldn't put the image on the lenses, you'd have to device a system where it projects a virtual image into the eye which appears to be a few feet away or so. Should be possible.

The idea here is to produce a "blurred" image by diffracting incoming light before it enters the cornea, that the eye then focuses with its internal lens. This is accomplished using the prismatic effects of "old school" LCD elements.
(Rememberr in the 90s whe color LCDs came out, with TFT displays? Remember how if you looked at them from an angle, all the colors were fucked up? That is because the color image was being created through prismatic diffraction.)
