Heads Up Display in Contact Lenses

Scientific American has a short discussion of the potential of displaying information in a person's contacts or on eyeglasses.

The new system consists of advanced contact lenses working in conjunction with lightweight eyewear.

Normally, the human eye is limited in its ability to focus on objects placed very near it.

The contact lenses contain optics that focus images displayed on the eyewear onto the light-sensing retina in the back of the eye, allowing the wearer to see them properly. Conventional mobile device screens are often too small to read comfortably "and certainly too small to enjoy," Willey said.

In contrast, Innovega's contact lenses could effectively generate displays with a screen size "equivalent to a 240-inch television, viewed at a distance of 10 feet."

Moreover, by projecting slightly different pictures to each eye, the display can generate the illusion of 3D. "You get full 3D, full HD, fully panoramic images," Willey said. |SA|
Based on the article, I believe this technology is still vaporware, but the potential for displaying pixels wirelessly in contact lenses has been demonstrated sufficiently that DARPA is now playing a funding role in developing this technology.

This gives me goosebumps on my fleshy parts.


  1. I also changed the break tags to paragraph tags in the blockquote, which looks much better with the Bellman's stylesheet.

  2. Why remove the image?

  3. Re: vaporware, there are multiple approaches making progress in the area of personal HUDs. I think we're on the verge of having it.

  4. I added a new image and edited the post slightly for grammar, in case anyone cares.
