A new artificial eye mimics and may outperform human eyes

A new design for an artificial eyeball (illustrated) could someday give keen eyesight to androids, or be used as a high-tech prosthetic. The design for a new artificial eye (illustrated) is based on the structure of the human eye. At the back of the eyeball, a synthetic retina is embedded with nanoscale light sensors. ThoseContinue reading “A new artificial eye mimics and may outperform human eyes”

Blind Woman Sees With New Implant, Plays Video Game Sent Straight to Her Brain

By Jason Dorrier t’s been over a decade since artificial retinas first began helping the blind see. But for many people, whose blindness originates beyond the retina, the technology falls short. Which is why new research out of Spain skips the eye entirely, instead sending signals straight to the brain’s visual cortex. Amazingly, 15 yearsContinue reading “Blind Woman Sees With New Implant, Plays Video Game Sent Straight to Her Brain”

Experimental technique makes it possible to perceive infrared light.

By David Freeman No one is ditching the night-vision goggles just yet, but scientists working in the United States and China have developed a technique that they say could one day give humans the ability to see in the dark. The technique involves injecting the eyes with particles that act like tiny antennae that takeContinue reading “Experimental technique makes it possible to perceive infrared light.”

Scientists Have Detected an Entirely New Visual Phenomenon in The Human Eye

by DAVID NIELD New research suggests the human eye and brain are capable of seeing ghosted images, a new type of visual phenomenon that scientists previously thought could only be detected by a computer. It turns out our eyes are more powerful than we thought. The discovery could teach us more about the inner workingsContinue reading “Scientists Have Detected an Entirely New Visual Phenomenon in The Human Eye”

Organic printing inks may restore sight to blind people

An array of semitransparent organic pixels on top of a ultrathin sheet of gold. The thickness of both the organic islands and the underlying gold is more than one-hundred times thinner than a single neuron. SUMMARY: A simple retinal prosthesis is under development. Fabricated using cheap and widely-available organic pigments used in printing inks andContinue reading “Organic printing inks may restore sight to blind people”

Praying mantises wearing tiny glasses help researchers discover new type of 3D vision

by Lacy Cook This praying mantis isn’t just wearing minuscule 3D glasses for the cute factor, but to help scientists learn more about 3D vision. A Newcastle University team discovered a novel form of 3D vision, or stereo vision, in the insects – and compared human and insect stereo vision for the very first time.Continue reading “Praying mantises wearing tiny glasses help researchers discover new type of 3D vision”

Thailand tribe children who see with perfect clarity underwater

By Helen Thomson “When the tide came in, these kids started swimming. But not like I had seen before. They were more underwater than above water, they had their eyes wide open – they were like little dolphins.” Deep in the island archipelagos on the Andaman Sea, and along the west coast of Thailand liveContinue reading “Thailand tribe children who see with perfect clarity underwater”

Google invents cyborg lenses for our eyes

by David Goldman Google has patented a new technology that would let the company inject a computerized lens directly into your eyeball. The company has been developing smart glasses and even smart contact lenses for years. But Google’s newest patented technology would go even further — and deeper. In its patent application, which the U.S.Continue reading “Google invents cyborg lenses for our eyes”

Eye tests may predict schizophrenia

Schizophrenia is associated with structural and functional alterations of the visual system, including specific structural changes in the eye. Tracking such changes may provide new measures of risk for, and progression of the disease, according to a literature review published online in the journal Schizophrenia Research: Cognition, authored by researchers at New York Eye andContinue reading “Eye tests may predict schizophrenia”

Student goes blind after keeping her contact lenses in for six months and microscopic bug eat her eyeballs

A student in Taiwan who kept a pair of disposable contact lenses in her eyes for six months has been left blinded after a microscopic bug devoured her eyeballs. The tiny single-cell amoeba ate away at undergraduate Lian Kao’s sight because she didn’t take out and clean the contacts once during that time. According toContinue reading “Student goes blind after keeping her contact lenses in for six months and microscopic bug eat her eyeballs”
