The development of a bionic eye that will restore vision to someone who is completely blind is a step closer after the research team working on the project detected signals in the brain from electrodes implanted in the retina of a living eye. The project, led by Associate Professor Michael Ibbotson from The Vision Centre and The Australian National University, has been investigating how artificial electrical signals can be converted into meaningful biological signals in the eye. It uses a...

NORTH CHICAGO, Ill., Nov. 30 /PRNewswire/ -- Using a high-output camera to film the back of the human eye, for the first time researchers have shown that a resveratrol-based (rez-vair-ah-trawl) nutriceutical matrix can effectively remove cellular debris from the human eye that accumulates with advancing age and correlated this with significant improvement in visual acuity and night vision in an 80-year old man. Resveratrol is widely known as a red wine molecule. To view the Multimedia News...

Journal of Vision article suggests potential treatment for blindsight patients Although we assume we can see everything in our field of vision, the brain actually picks and chooses the stimuli that come into our consciousness. A new study in the Association for Research in Vision and Ophthalmology's Journal of Vision reveals that our brains can be trained to consciously see stimuli that would normally be invisible. Lead researcher Caspar Schwiedrzik from the Max Planck Institute for Brain...

Two Kansas State University psychology researchers have found that although central vision allows our eyes to discern the details of a scene, our peripheral vision is most important for telling us what type of scene we're looking at in the first place, such as whether it is a street, a mountain or a kitchen. "I think the most surprising part of the study is that we didn't really expect peripheral vision to do that well at getting the gist of a scene," said Adam Larson, K-State master's...

Research shows for the first time that the brain can latch on to color and assign it to a different object Color is normally thought of as a fundamental attribute of an object: a red Corvette, a blue lake, a pink flamingo. Yet despite this popular notion, new research suggests that our perception of color is malleable, and relies heavily on biological processes of the eye and brain. The brain's neural mechanisms keep straight which color belongs to what object, so one doesn't mistakenly see a...

BOSTON, Aug. 31 /PRNewswire/ -- A high-tech device that expands the visual field of patients with tunnel vision has passed a collision test in a walking simulator, according to scientists at Schepens Eye Research Institute, in a study published in the September issue of Investigative Ophthalmology and Visual Science. The study found that patients wearing this innovative device, consisting of a tiny camera, pocket-sized computer and a transparent computer display on a pair of glasses, were...

A new study finds a surprising similarity in the way neural circuits linked to vision process information in both sighted individuals and those who have been blind since birth. The research, published by Cell Press in the August 13th issue of the journal Neuron, reveals that category-specific localized activation of a critical part of the visual cortex does not require any prior visual experience and provides fascinating and valuable insight into the evolutionary history of the human...

Arizona Cardinals' Wide-Receiver and Pro Bowl MVP, Larry Fitzgerald Encourages Parents to Take Action TODAY AURORA, Ohio, June 18 /PRNewswire-USNewswire/ -- The College of Optometrists in Vision Development (COVD) is launching their annual campaign to educate the public on the steps they can take to ensure their children aren't struggling with reading and learning because of undiagnosed vision problems. "The public doesn't realize that you need over 15 visual skills to succeed in reading,...

U.S. scientists have found a widely held theory concerning the brain and perception is incorrect and that the brain blocks some information from awareness. Rutgers University researchers have discovered visual input obtained during eye movements is processed by the brain, but blocked from our awareness. The process of seeing requires the eyes to move so light can hit the photoreceptors at the center of each retina, which then pass that information to the brain, the scientists said. "If we...

Researchers find widely held theory on "Saccadic Suppression" is incorrect with discovery that the brain is blocking information from awarenessResearchers at the Center for Molecular and Behavioral Neuroscience (CMBN) at Rutgers University in Newark have identified the need to develop a new framework for understanding "perceptual stability" and how we see the world with their discovery that visual input obtained during eye movements is being processed by the brain but blocked from...
