Researches are developing a new generation of contact lenses built with very small circuits and LEDs. They promises bionic eyesight in the future. Bionanotechnology researcher Babak A Parviz writes about his research toward producing a computer interface in a contact lens at IEEE Spectrum article Augmented Reality in a Contact Lens. The author states that, ‘All the basic technologies needed to build functional contact lenses are in place,’ and details what refinements and advances will be necessary to bring this technology to reality. The picture below is from the article.
haha … the one who is posting the comments
The best contact lens that i have used are the ones made by Bausch & Lomb. Very high quality and top of the line contact lens.-”,
Very interesting post thank you for writing it I have added your website to my favorites and will be back
By the way this is a little off subject but I really like your blogs layout.
this sort of thing will be AWESOME when it finally happens, Augmented reality is THE wave of the future
Recently, I did not give whole lot thought to commenting on weblog articles and have left feedback even less. Viewing your useful piece of writing, might inspire me to do this again.
I truly appreciate this article post. Really Cool.
Really informative blog post.Thanks Again. Cool.
I truly enjoyed this. It was very educational and useful. I will back to check on upcoming articles
I’ve been visiting your blog for a while now and I always find a gem in your new posts. Thanks for sharing.
Gratulations man, radio livestream spoke about your blog on 3 am. Header was your post Augmented Reality in a Contact Lens Tomi Engdahl’s ePanorama blog. Good work. bye-bye
You make a number of valid items in your article and would likely believe many.
First time at your blog and I really enjoyed reading it. I will come back again in the future to check out some of the other articles.
Wow this takes me back. Do you have a RSS feed?
Hey, maybe this is a bit offf topic but in any case, I have been surfing about your blog and it looks really neat. impassioned about your writing. I am creating a new blog and hard-pressed to make it appear great, and supply excellent articles. I have discovered a lot on your site and I look forward to additional updates and will be back.
This posting is invaluable, I deeply enjoyed it, I’m going to be back for much more!
I did not give whole lot thought to commenting on weblog articles and have left feedback even less. Viewing your useful piece of writing,
for me, the best contact lenses are those made by Bausch & Lomb, they are worth the price–’
I really adore your posts of late. If it’s not much trouble, can you maybe show how to create pieces such as this. Renita Cristobal
I’m not actually too familiar with this topic. I a bit more so just like to stop by blogs for layout tips and points like that. But you in fact developed a subest that i often care absolutely nothing about exceptionally intriguing. This can be a very good blog to design mine immediately after. I hope you do not mind if i bookmark your websites, in order that i can effortlessly get it once more within the future. Cheers.
Wow I am excited for this contact lenses development. Actually I am already happy with the available contact lenses now which can be used for corrective and therapeutic purposes, and cosmetic uses, as people can use cosmetic contact lenses to change their eye color. How much more if this is introduced?
i love to wear different colored contact lenses, i always tray them whenever i am at work –
contact lens are not only for fashion but it can also protect your eyes from dust and UV radiation ‘:`
I simply found your internet website a number of days ago and i are reading through it frequently. you have got a wide range of useful data on the site and i also love the particular sort of the location at identical time. continue the great work!
An individual built various advantageous facts presently there. I did looking with regard to inside the challenge and also noticed plenty of men and women may agree within your web page.
Greetings from Florida! I’m bored at work so I decided to browse your site on my iphone during lunch break. I enjoy the information you present here and can’t wait to take a look when I get home. I’m amazed at how quick your blog loaded on my phone .. I’m not even using WIFI, just 3G .. Anyways, amazing site!

Electronic contact lens displays pixels on the eyes

The future of augmented-reality technology is here – as long as you’re a rabbit. Bioengineers have placed the first contact lenses containing electronic displays into the eyes of rabbits as a first step on the way to proving they are safe for humans. The bunnies suffered no ill effects, the researchers say.
“We have demonstrated the operation of a contact lens display powered by a remote radiofrequency transmitter in free space and on a live rabbit,” says a US and Finnish team led by Babak Praviz of the University of Washington in Seattle.
“This verifies that antennas, radio chips, control circuitry, and micrometre-scale light sources can be integrated into a contact lens and operated on live eyes.”

Howdy! This is my first comment here so I just wanted to give a quick shout out and tell you I truly enjoy reading through your articles. Can you suggest any other blogs/websites/forums that cover the same subjects? Thanks for your time!
It’s appropriate time to make some plans for the future and it is time to be happy. I have read this post and if I could I wish to suggest you few interesting things or advice. Maybe you could write next articles referring to this article. I desire to read even more things about it!
Hi, i think that i saw you visited my website thus i came to “return the favor”.I’m trying to find things to improve my web site!I suppose its ok to use a few of your ideas!!
DARPA Works On Virtual Reality Contact Lenses
Digital images could be directly projected onto lenses to improve soldiers’ situational awareness.

DARPA Works On Virtual Reality Contact Lenses
http://tech.slashdot.org/story/12/02/02/028249/darpa-works-on-virtual-reality-contact-lenses
“Binoculars and night-vision goggles have their limits. So DARPA is doing work at Washington-based Innovega iOptiks to create wearable eye lenses with tiny, full-color displays onto which digital images can be projected, to give soldiers better situational awareness. The lenses would allow users to focus simultaneously on images that are both close up (perhaps a display) and far away (perhaps a battlefield.) Using virtual reality technologies to improve how soldiers perform on the battlefield has been a particular interest of the U.S. military for some
COMMENTS:
It looks like it may be similar to Innovega’s display at CES. Details (heavy in the marketing gloss) are available here. [innovega-inc.com]
To summarize, the human eye is pretty bad at focusing on things nearby. Close one eye and hold your hand a couple inches in front of the other, and you’ll see what I mean. In order to get around this so far, all the augmented reality glasses you refer to need to use some tricks to make it seem like the image is farther away than it really is. This makes the screens bulkier, more expensive, etc. The idea here is to create a contact lens onto which you can project an image so that it gets superimposed on one’s vision, in focus, without any trickery, thus simplifying the design and allowing the AR devices to be lighter, cheaper, maybe use less power, and so on.
