In the future, you might read e-mail on digitally enhanced contact lenses

By John D. Sutter, CNN

Thinking about this makes my eyes hurt.

Researchers at the University of Washington and Finland's Aalto University have developed a prototype of a contact lens that would project digital images onto the retinas of its wearer. And, for the first time, they actually tested the lenses on live creatures - in this case, rabbits that underwent anesthesia.

That may seem like it's out of left field, but researchers for years have been working on the idea that we should somehow overlay digital information on top of the real world. Lots of smartphone apps, including Wikitude, Spyglass and Golfscape – as well as some prototypes for "Terminator" glasses - are trying to do this.

As these researchers noted this week in the Journal of Micromechanics and Microengineering, contact lenses that display digital information are the holy grail for this genre of reality-bending work. Eventually, projected displays from contact lenses could replace all the other screens we look at. You could end up reading your e-mail on your contacts.

Here's the paper's description of the future of "augmented reality":

Wearable computing will likely provide new ways to manage information and interact with the world. For example, personal see-through devices could overlay computer-generated visual information on the real world, providing immediate, handsfree access to information. The first step toward always-accessible information and superimposed, data-rich imagery will most likely be implemented in see-through eyeglass displays. Ultimately, a much less cumbersome display for augmented reality may take the form of a contact lens.

The lenses, they say, could communicate with other gadgets to send and receive information:

In the future, contact lens systems may receive data from external platforms (e.g. mobile phones) and provide real-time notification of important events. As contact lens based biosensors advance, they may alert the wearer of physiological anomalies, such as irregular glucose or lactate levels. With more colors and increased resolution, contact lenses may display text, be used with gaming devices, or offer cues from navigation systems. Our long-term goal is to create a display that can be comfortably worn in the form of a contact lens, which will include a pixel array, focusing optics, an antenna, and circuitry for power harvesting, radio communication, and pixel control.

But don't get too excited just yet. So far, the prototype contact lens developed by these researchers only displays one pixel's worth of data. And, so far, they've only tested the lens on rabbits.

Challenges abound when you're trying to store and project data from tiny contact lenses, the researchers say. For one, it's difficult to attach an antenna and a power source to something as small and thin as a contact - and to do so without obstructing vision. They settled on an antenna that wraps around the edge of the contact lens. And the researchers used radio frequencies - within federal limits, they said - to help the lens communicate with wireless sources.

Check out this video for some more info on how these lenses are built:

Despite the limitations of this prototype, the research team is hopeful about the future of augmented reality, as presented by digitally enhanced contact lenses. This was the first demonstration that showed a contact lens fitted with radio chips, antennas and a light source could be "operated on live (rabbit) eyes."

And even though the lenses only showed a single dot of digital light, there's a lot you could do with that, they write.

A display with a single controllable pixel could be used in gaming, training, or giving warnings to the hearing impaired. We also believe it is possible to develop systems with better resolution, color, range and computing power. Displays with a handful of pixels could be used to provide directional information, and displays with hundreds of pixels used to read short emails or text messages. Although high resolution, full-color, stand-alone contact lens displays might be many years away, the technological demonstrations to date depict a clear path containing a number of useful intermediate devices that can be feasibly produced in the near to medium terms. If such displays were successfully deployed, they would fundamentally change the nature of interaction between humans and visual information.

Let's just hope they have an off switch for driving.

    aily wear soft contact lenses are typically the least expensive option. You wear the lenses during the day, and remove them each night to be cleaned and disinfected. How long you can use a single pair of daily wear lenses varies depending on the manufacturer...:.-

    Quality of vision correction is one area where contact lenses are superior to glasses no matter who you are. Since the lens part of contact lenses sits directly on your eye and covers the seeing part of your eye completely, you will have corrected vision all around, including to the top, bottom, and sides, whereas with glasses, there is no correction for your peripheral vision. That can be problematic for activities like driving, or if the quality of your vision is important in your profession...

    Can anyone not focus on the possible and I do say possible downfalls. Think of this, people who cant see at night can now have these contacts and see perfectly, If you were hit by a car or there was a shooting and a car drove by you could focus on the licence plate and take a picture of it. They could be used as binoculors to see things that you would not ordinarly see. People that are deaf would benifit from this emencly. I hate how people always jump to the problems or potential problems.

    Next is a molar (tooth) transceiver for phone calls and RF transceiving. The special filling has an antenna and accepts AM/FM frequencies. No need to implant a small speaker, for the user can hear through his/her mouth. Right after that the "butt" fax will hit the market. It will be capable of sending and receiving faxes, with a fart indicating incoming fax notification so the user knows to attach the rectal device to a virtual printer. I shudder to speculate on where the paper goes for an outbound fax. Use your imagination.

    Nonsense. It CAN"T be like the Terminator where you have a clear field of view in the center and other informatin around the edges. That only works in the movies because as you are watching the movie, you can move your eyes and look at the edge of the screen and read the information. If it you have a contact lens projecting information on the edge of your field of view, you can see that something is there, but you can never read it because when you move your eye to look at it, it always moves away. The only way to read anything would be to project the text onto your fovea centralis (smack dab in the center of your field of view) in which case it would distract you from noticing the car you are about to crash into (even if you could technically see the car past the text). You would still have to stop everything else you might be doing in order to read e-mail, in which case it is no more convenient than reading e-mail on your smartphone, unless you are trying to hide the fact that you are reading e-mail and not paying attention.
