Peek is a smartphone-based eye-testing kit being developed in the UK (Photo: Peek)

A new smartphone-based portable eye examination kit called Peek is aiming to bring hope to people suffering from eye problems who live in remote parts of the world. Besides being portable and easy to use, system makes it possible to perform complex eye tests with no need for expensive equipment.  Read More

Unfortunately, there aren't many options available for the visually impaired when it comes to timepieces. While a number of talking watches and braille wristwatches with removable covers are already on the market, those often draw attention to a person's disability. That's why watchmaker Eone's debut timepiece, the Bradley, indicates the time with magnetic ball bearings that can be read subtly by touch.  Read More

OrCam's camera device, attached to a pair of glasses by a small magnet (Photo: OrCam)

The OrCam is a small camera linked to a very powerful wearable computer. It sees what you see and through your finger-pointing understands what information you seek, relaying auditory feedback through a bone conduction earpiece. Using an intuitive user interface, the device can read text, recognize faces, identify objects and places, locate bus numbers and even monitor traffic lights.  Read More

Scientist have developed microrobots that may be able to help prevent blindness

Just like other parts of the body, the retina needs oxygen in order to survive. If it doesn’t receive enough – should its blood supply be restricted, for instance – permanent blindness can result. Therefore, the sooner that doctors know if a patient’s retina is receiving insufficient oxygen, the better the chances that they can take action in time. Soon, they may be able to use tiny injectable robots to get them the information they need.  Read More

In the Spider-Man comics and movies, the famous hero's "Spider Sense" warns him of incoming danger, which proves to be just as important a superpower as slinging webs and climbing walls. Now a group of researchers at the University of Illinois in Chicago may have found a way to replicate such superhuman perception that doesn't involve any radioactive spiders. Using a collection of sensors placed all over the body, the group has designed a "SpiderSense" suit that detects objects in the environment and warns the wearer when anything gets too close.  Read More

Argus II consists of a tiny video camera mounted in glasses that is wirelessly linked to a...

While the word prosthesis usually evokes images of artificial legs, arms, and these days even sophisticated thought-controlled hands, an entirely new class of replacement body part has now become a reality – the bionic eye. One of the pioneers in this field is California-based Second Sight and the company has now announced that its Argus II System has received U.S. market approval from the Food and Drug Administration (FDA).  Read More

The basic components of the Argus II Retinal Prosthesis, used in the experiment

Second Sight’s Argus II Retinal Prosthesis is definitely an interesting piece of technology, allowing a blind user to “see” objects, colors and movement in their environment. Ordinarily, this is done with the help of a video-camera-equipped pair of glasses worn by the user. In a recent experiment, however, researchers bypassed the camera, transmitting visual braille patterns directly to a blind test subject’s retina.  Read More

A new understanding of eye cells may lead to a treatment for blindness (Photo: Shutterstoc...

There could be new hope for people facing vision loss due to conditions such as retinitis pigmentosa or wet age-related macular degeneration. Scientists from the University of Southampton have discovered that easily-gathered corneal cells may be able to take the place of degraded retinal cells, thus preventing or curing blindness.  Read More

In an effort to enable blind people to navigate their surroundings more safely and effectively, researchers at Israel’s Weizmann Institute of Science have drawn inspiration from an unexpected source: rat whiskers.  Read More

Researchers have reportedly restored near-normal vision to blind mice, using a prosthesis ...

Retinal prostheses such as the Argus II, Bio-Retina and the Retina Implant AG microchip all work – more or less – by stimulating the retina’s ganglion cells with light-induced electrical signals. The images produced in the patient’s visual cortex tend to be quite rudimentary, however. This is partially because the rate at which the signals are sent isn’t the same as the rate of neural impulses normally produced by a retina. Now, researchers have deciphered the neural code used by mouse ganglion cells, and used it to create a prosthesis that reportedly restores normal vision to blind mice. They have additionally deciphered the neural code of monkeys, which is close to that used by humans, so a device for use by blind people could also be on the way.  Read More
