Nano-Sized Semiconductor Dots Could Fix Your Terrible Vision

New Scientist reports that researchers at the University of Colorado came up with this crazy idea that if they inject semiconductor nanoparticles in your retinas, photons will make them glow, thus improving your vision.

In 2005, Tanya Vlach lost an eye in a car accident and has since worn the prosthetic pictured above. While the artificial eye is "an excellent aesthetic replacement," Tanya notes that she is "interested in capitalising on the current advancement of technology to enhance the abilities of my prosthesis for an augmented reality." In other words, she is calling out to skilled DIY'ers across the internet to help her build a high-tech "eye-cam." But this isn't just about helping people—what she has in mind is just plain cool.
A contact lens case for disposable lenses with a built-in back-lit LCD timer with customisable delay so you know when to replace your lenses. That's about all I need to say about Countact. The battery's built-in, so you can't replace it when it dies after about 3 months: but you all know you should change your case regularly no? Otherwise you'd get a nasty infection which'd mean we'd have to write Giz in BIG LETTERS so your crusty eyes could read it. A four-pack'll cost you $US34. [
The eye is a delicate thing. Most ocular implants that get too hands-on with your squishy sightballs cause rejections problems, but
The nurse applied a series of numbing drops to my eyeball, each stronger than the previous. The doctor clamped my lids back with a metal tool. I felt a bracket hold my eye down and someone in the operating room gave the order, "Suction."
Researchers at UC Davis have designed contact lenses that can give you an in-eye checkup to make sure there's nothing wrong, as well as dispense medication automatically when needed. The "smart" lenses use an organic polymer called PDMS (polydimethylsiloxane, if you're nasty) that detects eye pressure and sends that data to a computer--important updates to get if you're at risk for glaucoma.
If you are serious about photography, at one time or another you may have considered how the human eye reacts to an image. After all, it is logical to assume that possessing information about what entices the eye can help you take much more powerful photos. If you could use a little education in the subject, the folks at PopPhoto have put together a comprehensive analysis called
Sporry guyss, there'lll be speling mistkes in this post coz I cnt see the keyboord proply: my eyess ar watercingg to much. *dab dab* Ah that's better. Just don't think too much about the eyelid jewellery from designer Eric Klarenbeek, or your eyes too will fill up in sympathy with that poor model. Wearing jewels dangling from contact lenses stuck to the front of her eyeballs. Ten out of ten for ingenuity, minus several million for practicality...that'd be my stance on these. Still, it's a weird world out there, so these will appeal to someone. Oh darrrn, I justu watchd the videoo... *drip*
Another reason I'm glad I was never a rave kiddie whenever it was trendy in the US: Trippy lasers beamed into your eyes will blind you. A gaggle of Russian ravers at the July 5 Aquamarine Open Air Festival discovered this after tents erected to deflect heavy rains partially refracted lasers intended for skyward illumination into their eyes, resulting in nastiness: "Retinal burns, scarring is visible on them. Loss of vision in individual cases is as high as 80 percent, and regaining it is already impossible." Ouch. Strangely, this makes me want to watch Go. [
Bionic eyes that return sight to the blind might not be as far off as previously thought, with researchers in London carrying out the first treatment on a pair of patients in a study of a new technology.
