Scientists create ultra-thin membrane that turns eyes into lasers
It will still be a while before scientists are able to harness Superman-like laser vision, but the technology is now closer than ever before thanks to a new development from the University of St Andrews. The team there have created an ultra-thin membrane laser using organic semiconductors, which is for the first time compatible with the requirements for safe operation in the human eye. Even though the membrane is super thin and flexible, it's durable, and will retain its optical properties even after several months spent attached to another object, such as a bank note or, more excitingly, a contact lens.
Second Sight retinal prosthesis cleared for sale in Europe, a better one already in development
We'd bother with the obvious, but there's no sense in acting exasperated that this thing is finally shipping -- let's just be glad it didn't take a day longer, shall we? Second Sight, a California-based company aiming to help those with degenerative eye disease by way of technology, has finally seen its flagship product approved for "clinical and commercial use" in Europe. The product is the Argus II, and for all intents and purposes, it's a retinal prosthesis (read: implant) that can at least partially restore lost vision. It works a little like this: patients don the camera-laden glasses, where signals are grabbed and fed wirelessly to a chip implanted near ones retina. The information is beamed to around 60 electrodes that "stimulate retinal cells, producing light in a patient's view." According to Technology Review, "the process works for people with retinitis pigmentosa because the disease damages only the light-sensing photoreceptors, leaving the remaining retinal cells healthy." For now, the $115,000 device will only be available through a smattering of clinics in Switzerland, France and the UK. If all goes well, it'll be actively seeking FDA approval next year for use in the US of A, and a version with way more electrodes shouldn't be too far behind.
Robins can see magnetic fields with a keen right eye
When it's time to migrate, how do birds find north? The going theory is that some avians can literally see the magnetic fields. Talk about a birds-eye view. However, a recent experiment shows that ability is hampered unless the creature in question has good vision in the right eye. Outfitting a variety of European robins with goggles frosted on one side and clear on the other -- but transmitting the same amount of light to both eyes -- a team of researchers at Goethe-Universitat in Germany discovered that the birds with blurred vision in their right eye were disoriented, while those with obscured sight on the left headed north without delay. Since we mastered the compass ages ago, there are precious few lessons here for robotic bird builders -- but perhaps once these scientists are satisfied with ocular experiments, they'll get around to figuring out how carrier pigeons manage those cellphone-smuggling return flights.
British surgeons using radiation beams to halt macular degeneration
We've seen more eyesight restoration efforts than we could easily count, but rather than tooting their horn about some theoretical discovery, boffins at Kings College Hospital in London are actually putting their hard work to use on real, live human brings. The new process, which goes by the name brachytherapy, is a one-off treatment for macular degeneration. In essence, surgeons carefully light up a beam of radiation within the eye for just over three minutes, which kills harmful cells without damaging anything else. A trial is currently underway in order to restore eyesight in some 363 patients, and everything thus far leads us to believe that the process is both safe and effective. As for costs? The procedure currently runs £6,000 ($9,889), but that's still not awful when you consider that existing treatments involving injections run £800 per month. Hop past the break for a video report.
NTT DoCoMo's eye-controlled music interface evolves at CEATEC (video)
NTT DoCoMo's R&D labs are amongst the busiest in the world, and here at CEATEC the company is showing off a development that it has had in the oven for quite some time. The difference now? Elegance. The eye-controlled music interface that we first spotted in mid-2008 is being showcased yet again here at the Makuhari Messe, but instead of having a short straw-drawing employee stand around with an absurd amount of headgear on, this year's demonstrator was equipped with little more than a special set of earbuds, a few cables and a swank polo. Put simply, the contraption watched subtle changes in eye movements and altered the music accordingly. A look to the right moved the track forward, while a glance to the left went back a track. The demo seemed buttery smooth, but there's still no telling when this stuff will go commercial. Still, progress is progress, and there's a video after the break showing as much. %Gallery-74737%
Filmmaker hopes to replace false eye with webcam, become a superhero
There are quite a few eerie similarities between Rob Spence and Tanya Vlach. For starters, they're both artists, and secondly, they both currently have one prosthetic eye. The real kicker? Each of 'em wants a camera stuck in there instead. In what we can only hope is (or isn't?) a freakishly growing trend, Mr. Spence has reportedly sought consultation from the University of Toronto's Steve Mann, a self-proclaimed expert in the field of wearable computing and cyborgs. Essentially, Rob is hoping to install a webcam in his eye socket in order to become a so-called "lifecaster." The camera wouldn't actually be wired to his brain, thus his level of vision would remain subpar, but it would make him a living science experiment that would surely prove insightful to an array of others. As of now, it sounds like the road to installation is long, but we get the impression that this guy isn't apt to give up until the proverbial fat lady begins to bellow.
Glaucoma monitoring contact lenses crafted at UC Davis
Far from the first circuit-laden contact lens we've laid eyes on (ahem), researchers at UC Davis have more than bragging rights in mind with their "smart" contacts. The devices are infused with a "pattern of conductive silver wires, which could be used to measure pressure inside the eye." The material, dubbed polydimethylsiloxane (PDMS), would boast antimicrobial properties and could enable scientists to better study glaucoma. How so? By sending pressure data to computers sans wires. Better still, the contacts also include the ability to automatically dispense medication into the eye, making this beneficial in more ways than one. The creators are expected to apply for approval to begin testing the lenses in humans here shortly, and barring any unforeseen (sorry, totally unintentional there) setbacks, we would hope these could be put to use within the next few years.[Via medGadget]
5.5 designers put eyeball details on lamps, weird us out
It's hard to say what kind of individual seeks out lighting instruments that even look like eyes, let alone lighting instruments with cloned details of their own eyes, but just in case you know one such person, here's the perfect FYI for 'em. Paris-based 5.5 designers are offering a service that enables you to send in images of your eyes (along with a very large sum of money, we presume) in order for the craftspeople to construct eyeball lamps with hints of you splashed all over. Sure gives Rockwell's one and only jam a whole new meaning, yeah?[Via ShinyShiny]
NTT DoCoMo testing out eye-controlled music interface
If you're scouting the strange, the weird and the weirder, you'll find plenty to get absorbed in over at the research facilities of NTT DoCoMo. The Japanese giant is at it once more, but this time the invention is actually somewhat down to Earth. It's mission? To create a method for easily controlling a music interface (on a PMP or cellphone) with just your eyes. By rolling one's eyes and jerking them from side to side, the outfit is hoping to have the corresponding music player change tracks and get louder / softer. If you're not exactly keen with freaking out fellow citizens on the street with completely erratic eye movements, you may also appreciate a similar technology it's working up which can detect a user's finger tapping to achieve to same goal. Of course, said technology would be halfway useless on the smash hit-packed ZVUE Journey (no way you're bypassing any of those tracks, son), but we guess you could check out your toes every now and then to keep from constantly staying at 11.[Via ShinyShiny]
GM designing car windshield that does the looking for us
Apparently not everyone at General Motors is toiling away in an attempt to get the Volt ready for its 2010 debut, as another sector of the outfit's R&D division is busy creating a windshield that will, at its core, enable us to stop running stuff over. The futuristic glass would utilize lasers, sensors and cameras in order to help drivers see the road's edge better, recognize obstructions and enhance things ahead of us so we'll theoretically react faster. Truth be told, the device is being designed with older drivers in mind, though we don't see why younger motorists won't benefit all the same. Unfortunately, it sounds as if you'll have to keep those toothpicks in your eyelids for a few more years, but at least we're one step closer to full-on autopilot.
Powerful lasers damage eyesight of some Russian ravers
Here's one straight from the bizarro chapters. Dozens of individuals that attended an all night dance party near Moscow have been "partially blinded after a laser light show burned their retinas," according to Russian health officials. Apparently someone responsible for erecting the equipment decided to aim a few lights powerful enough to brighten the night sky down at the crowd (after rain necessitated a makeshift roof, we're told), with some of those who stared too long losing up to "80%" of their vision. We're not exactly sure what will happen to the promoters of the event, but at least now you have a valid excuse to rock those face-engulfing sunglasses (or a welding mask, if you're really paranoid) in every night club you waltz into.[Via Switched, image courtesy of iGouGo]
Bio-electronic implant seeks to restore partial sight
We've seen initiatives all over the globe created in an attempt to beat blindness, but researchers based at MIT are feeling fairly confident that their development is within a few years of being able to "restore partial sight to people who have slowly gone blind because of degenerative diseases of the retina." The bio-electronic implant, which is about the size of a pencil eraser, would actually sit behind the retina at the back of the eyeball, and images would be transmitted to the brain "via a connector the width of a human hair." As it stands, an FDA grant application is already in the works, and the scientists are hoping to have it implanted in an animal as early as this summer. Still, the solution only works for folks who "were once able to see and have partially intact optic nerve cells" -- those who were blind from birth or suffer from glaucoma are unfortunately ineligible for the procedure.[Thanks, Rusty]
Researchers clear up TV watching for visually impaired
Yeah, we've got HMDs for the visually impaired, but seriously, who's for sporting one of those things just to catch an afternoon soap? Thankfully, Dr. Eli Peli (and colleagues) from Harvard Medical School is lookin' out for said sect, and has developed a method for "enhancing the contrast of images of people and objects of interest on their digital televisions," which, during trials, was found to enhance legibility and overall enjoyment when watching. Furthermore, the technology is said to be the first to play nice with digital TV images, which seems fairly important considering that analog signals have but a few months to live here in America. Purportedly, the all-important modification that made the adjustments possible could be applied to HDTVs and digital STBs in the future, and sure enough, Peli has already sparked up conversation with Analog Devices in order to create a prototype chip for use in forthcoming sets. Now, if only clearing up those Get Smart reruns were this simple...[Via InventorSpot, image courtesy of Harvard (PDF)]
Artificial corneas could save eyesight
While there's been no shortage of research surrounding the saving of one's eyesight, the EU-funded CORNEA project has now developed an artificial cornea that is showing promise in trials. Reportedly, scientists at the Fraunhofer Institute for Applied Polymer Research IAP in Potsdam and the Department of Ophthalmology at the University Hospital of Regensburg have created a device that is "based on a commercially available polymer which absorbs no water and allows no cells to grow on it." Put simply, the cornea implant can "firmly connect with the natural part of the cornea, while the center remains free of cells and therefore clear." Apparently, early versions have already been successfully placed in the eyes of rabbits, and if ongoing testing goes smoothly, they'll be headed for humans as early as next year.
Panasonic develops walkthrough iris scanner to hasten ID checks
Snappy retinal scanners have been in the works for some time, and now Panasonic is apparently hoping to hasten those annoying ID checks by enabling security personnel to confirm the true identity of a person walking through in just "two seconds." Additionally, this scanner does not require subjects to "focus on the equipment," packs "multiple two-megapixel cameras," and in case you couldn't guess, is being marketed towards airports and high-security office buildings. No word just yet on when these may be rolled out for public use, but anything (well, almost) that speeds up our traveling is smiled upon by us.[Via TechDigest]
MIT researchers develop speedy retina scanner to diagnose ocular diseases
Although the mere mention of "retinal scanner" may get the blood boiling in privacy advocates, the latest such device out of MIT sports a much more innocent soul. Researchers at the school have reportedly developed a method to "scan the retina at record speeds of up to 236,000 lines per second, or ten-times faster than current technology." This process will allow doctors to snap "high detailed 3D images of the eye," which can be used to non-invasively spot ocular diseases such as diabetic retinopathy, glaucoma, and age-related macular degeneration much earlier and more accurately. The process itself is dubbed optical coherence tomography (OCT), and while things seem to moving along as scheduled, it will still be "five years or more" before we see this thing commercialized.[Via MedLaunches]
