While it is not (yet) possible to restore vision in most cases to someone with a severe form of impaired vision, technology continues to advance. By using a brain implant, researchers have restored a rudimentary form of vision in the blind.

Scientists are a step closer to restoring vision for the blind, after building an implant that bypasses the eyes and allows monkeys to perceive artificially induced patterns in their brains.

Robotics continue to advance but the development is often limited by the extent that robots can 'see' and then process visual imagery in order to coordinate movements. A new '6D' process aims to overcome this.
|
|
A new study demonstrates that humans can think like computers. The research indicates how artificial intelligence is narrowing the gap between the visual abilities of people and machines, resulting in computers edging closer to how people think.

Manchester -
New research has revealed how animals see, by the use of a novel chemical compound. The compound stimulates retinal neurons under low-light conditions, triggering retinal activity to increase.

New Haven -
By assessing precise brain measurements, scientists have successfully predicted how people's eyes move when viewing natural scenes. Understanding this is the key to improving visual-based artificial intelligence.

The fruit fly (Drosophila melanogaster) occupies a world where it senses the environment through touch and smell. What isn’t clear is the extent that the fly visually interprets the world. To explore this, researchers have turned to machine learning.

To help to understand how color vision develops researchers have successfully grown human retinas in a Petri dish. These bio-constructs will allow for different theories to be tested.

London -
A psychological study concludes that men and women examine faces if other people differently and absorb visual information in different ways. This suggests a gender difference in understanding visual cues.
|
|
Scientists had thought a recent gene-therapy trial to be successful. Here the study participants experienced some restoration of sight. However, the people now seem to be losing their vision.

Tokyo -
Rats that have lost their eyesight can sense direction with the aid of a neuroprosthesis. This consists of a geomagnetic compass and a microstimulator with electrodes implanted in the animals’ brains, according to a new study.

Glasgow -
The babies of mothers who are classified as drug addicts are more likely to be born with developmental problems and poor vision, according to a new study.
|
Toronto -
The Canadian Association of Optometrists (CAO) recently reminded people of the importance of routine eye exams. This is because diabetes can have a significant impact on eye health.
|
Tel Aviv -
Researchers have developed a new light-sensitive nanotube-based film. The technology could pave the way to more flexible and durable retinal implants.
|

Berkeley -
Experiments with vision and technology have yielded a display which can change to fit your eyes. Early research does not answer all the questions but provides a promising start for future vision technology.
|
Researchers have used a type of human stem cell to create a three-dimensional complement of human retinal tissue in the laboratory. The retina includes functioning photoreceptor cells capable of responding to light.
|
A new national survey has revealed that only 9 percent of U.S. women realize that women are at greater risk of permanent vision loss than men. This news comes during a month dedicated to women’s eye health issues.

Did you know that adding certain nutrients to your diet every day, either through foods or supplements, can help save your vision? By adding powerful antioxidants to your diet, you can greatly improve your eye health, according to an eye specialist.

Atlanta -
According to the U.S. CDC, April is Women’s Eye Health & Safety Month. This year there are two themes: ‘Eye Safety at Work’ and ‘Healthy Vision: Make It Last a Lifetime.’
|
New research shows how, by converting sights to sounds, the brains of congenitally blind people respond similarly to various objects in a similar way to people who can see.

Steven Holcomb, a gold medalist at the 2010 Vancouver Olympics, a bobsledder, has gone from attempting suicide to creating a legacy for people with eye diseases. He describes his life in a new book.
|
Following a gene therapy trial, patients who were progressing toward blindness now have better vision after completing the treatment.
|
A new study suggests that sleeping on one side may worsen glaucoma. The study also suggests that people with worsening glaucoma on just one side were also more likely to sleep with the affected eye facing downward.
|
|
In the U.S., January is Glaucoma Awareness Month. During the month a range of different events are being hosted and health promotion schemes implemented.
|
A study of stem cell therapy using patients’ own cells, reprogrammed to be stem cells, to treat vision loss has been approved in Japan.
|
Scientists have discovered a thin, durable layer near the back of the cornea. This find could lead to safer corneal surgeries.
|
New technology has been developed which may be able to help people, suffering from degenerative eye diseases, to see. The technology harnesses holographic imaging.
|
The race to deliver an effective bionic eye is alive and well with researchers in Australia, the U.S. and Germany reaching important milestones and undertaking patient trials.

Beersheba -
The archer fish, which spits a stream of water at its prey, can see its target pop out of the background even though it has no visual cortex, the complex brain region thought to enable humans to perform the same perceptual feat, according to a new study.
|
|
A prototype 'bionic eye' designed to restore sight of people with failing vision was unveiled in Australia Tuesday. The Australian government-funded project aims to do a human implant of the device by 2013.

"It took seven years to find a way to discover the notation that would allow that incredible sound to be reproduced," Thome says of the vision that inspired his use of mandalas. "I have now come to realize that we do not find the Mandala...The Mandala finds us... and stirs in the twilight of our dreams. This notation brought me closer to the sound than Western notation ever could." Joel Thome
