You may consider your eyes a priceless commodity, but for Mexican cavefish, they were a burdensome expense. In a first-of-a-kind study, scientists have figured out exactly how much energy an animal saves by abandoning vision — in this case, anywhere from 5 to 15%.
Echolocation isn’t just for bats and dolphins—people can do it, too. Some blind people have learned to use echolocation to tell the size, density, and texture of objects around them, and researchers believe anyone can learn how.
What does space feel like? I'm not talking about space itself—but rather the images we see in a telescope. Could you render those spectacular images into something that a blind person could experience? That's exactly what a pair of astronomers are trying to figure out.
It's not every day that science and crazy brain implants lead to the generation of what is essentially a new sense, but it is that day today. Scientists from Duke University have found a way to make rats "feel" invisible infrared light and someday that same tech could give sight to the blind, or give us humans extras…
Some mice that once were blind can now see, thanks to a breakthrough from researchers at UC Berkley. And humans might not be far behind.
Have you ever wondered what it might be like to be temporarily blind? Of course you have. In fact, there is a way to trick your body into becoming blind, at least for a few minutes.
Not that one should go around shaming seeing-eye dogs. But the Tacit haptic glove, designed by Steve Hoefer, is a little DIY project that fires sonar from the wrist, keeping a visually impaired individual aware of their surroundings.
There's a terrible hereditary eye disease called Leber's hereditary optic neuropathy that affects men in their twenties. It's a mitochondrial disease inherited from your mother that leads to total blindness within six months of onset.
It's no David Copperfield, but in this day and age surely that's a good thing? Winner of the Best Illusion of the Year contest, this moving circle of dots tricks the eye into seeing changing color even when they're not.
A Japanese research team has successfully grown a "rudimentary" mouse eye in a petri dish using stem cells. This has many implications for future research and curing blindness. Above is a time-lapse video of the stem sells spontaneously organizing into an "optic cup"—the precursor to an eye. Now they need to grow a…
So the Wicked Laser was a letdown, but it's still super dangerous, so that's kind of cool, right? We wondered what it might be like to get Wicked lasered in the eyeball. So we shot one into a camera. Ouch.
Lance Corporal Craig Lundberg lost his sight to a rocket-propelled grenade in 2007. Now, thanks to a fascinating technology, he can read words and make out shapes using his tongue. It's truly incredible.
Intel's Reader, developed by a dyslexic Stanford graduate, is a powerful device for dyslexic and visually impaired readers, allowing them to scan entire pages of text to audio for immediate playback or later review.
MIT researchers are developing a microchip that adheres to an eye to revive sight, and it could begin human trials within three years.
Here's something that people with poor or no vision will be excited about: three patients had their sight restored in less than a month by contact lenses cultured with stem cells.
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…
