Bionic contact lens 'to project emails before eyes'

A new generation of contact lenses that project images in front of the eyes is a step closer after successful animal trials, say scientists.
The technology could allow wearers to read floating texts and emails or augment their sight with computer-generated images, Terminator-syle.
Researchers at Washington University who are working on the device say early tests show it is safe and feasible.
But there are still wrinkles to iron out, like finding a good power source.
Currently, their crude prototype device can only work if it is within centimetres of the wireless battery.
And its microcircuitry is only enough for one light-emitting diode, reports the Journal of Micromechanics and Microengineering.

Our next goal is to incorporate some predetermined text in the contact lens”
Lead researcher Professor Babak Praviz
But now that initial safety tests in rabbits have gone well, with no obvious adverse effects, the researchers have renewed faith about the device's possibilities.
They envisage hundreds more pixels could be embedded in the flexible lens to produce complex holographic images.
For example, drivers could wear them to see journey directions or their vehicle's speed projected onto the windscreen.
Similarly, the lenses could take the virtual world of video gaming to a new level.
They could also provide up-to-date medical information like blood sugar levels by linking to biosensors in the wearer's body.
Delicate materials Lead researcher Professor Babak Praviz said: "Our next goal is to incorporate some predetermined text in the contact lens."
He said his team had already overcome a major hurdle to this, which is getting the human eye to focus on an image generated on its surface.
Normally, we can only see objects clearly if they are held several centimetres away from the eye.
The scientists, working with colleagues at Aalto University in Finland, have now adapted the lenses to shorten the focal distance.
Building the end product was a challenge because materials used to make conventional contact lenses are delicate.
Manufacturing electrical circuits, however, involves inorganic materials, scorching temperatures and toxic chemicals. Researchers built the circuits from layers of metal only a few nanometres thick, about one thousandth the width of a human hair, and constructed light-emitting diodes measuring one third of a millimetre across.
Dr Praviz and his team are not the only scientists working on this type of technology.
A Swiss company called Sensimed has already brought to market a smart contact lens that uses inbuilt computer technology to monitor pressure inside the eye to keep tabs on the eye condition glaucoma.

This is just weird ... no offense to those of you who find findings like these great and ... moving forward?

I think its great if they can find something to keep tabs on the glaucoma,we have lost 3 people to glaucoma cancer grade 1 tumors very quick silent killer it is.

Glaucoma isnt cancer. It just causes damage to the optic nerve, causing blindness.

Going back to the article, i think more tests should be done.

Eye cancer-related glaucomas occur through a variety of mechanisms. They can be challenging to diagnose and are often refractory to treatment. The literature reveals the variety of ways eye cancers cause glaucoma. Mechanisms include direct invasion, infiltration, or seeding of the aqueous outflow structures as well as indirect processes, such as compressive angle closure and anterior segment neovascularization. This review describes established, evolving, and new diagnostic techniques (e.g., high-frequency ultrasound and aspiration biopsy techniques). Treatment options typically depend upon the tumor type (primary or secondary), its location, and mechanism of glaucoma. However, they include standard pharmacologic, laser, incisional, and radiotherapeutic approaches. We hope this review leads to early detection and optimum treatment of eye cancer-related glaucomas. Clearly, prompt diagnosis and management of eye cancer-related glaucoma offers an opportunity to both preserve vision and the patient's life.




you got your article from here

Eye cancer related glaucoma: current... [Surv Ophthalmol. 2009 Jan-Feb] - PubMed - NCBI (http://www.ncbi.nlm.nih.gov/pubmed/19171210)

it doesnt prove that it is cancer.
Once again, cancer and glaucoma are not the same thing. Yes, one can lead to the other, however, its not a form of cancer. Here is a link for it The Prairie Eye Center (http://docs.google.com/viewer?

Doctor Newton one of the biggest specialist in UK must have been dumb then when he diagnosed my grandmother who died of glaucoma cancer with in 4 weeks, if she had sat in one place and wasn't always flying back and fwd opticians would have caught the fluid pressure build up in the eye before it was too late,as well her two brothers just like they caught my fathers in time.
I am not trying to bring anything personal here, i am speaking from a science and health perspective. However to get back on this, it seems that its inherited, and maybe your relatives may not have even known they had it before, making it too late for proper treatment/diagnosis. Because many times symptoms are not shown in the beginning or early stages. Diabetes can also go in link with this eye disorder/disease.

Maybe I should finish reading stuff :/ lol
