OrCam aims to improve quality of life for the visually impaired

OrCam aims to improve quality of life for the visually impaired | Longevity science | Scoop.it

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.

Could stem cells repair damaged cones in retinas, allowing for daylight color vision? | KurzweilAI

Could stem cells repair damaged cones in retinas, allowing for daylight color vision? | KurzweilAI | Longevity science | Scoop.it

For some time geneticists have known that stem cells in zebrafish can replace damaged vision cells.

 

This study showed that cone damage, rather than just rod damage, is possible with these stem cells.

GRIN optical technology could mean better implantable lenses

GRIN optical technology could mean better implantable lenses | Longevity science | Scoop.it

Artificial implanted lenses, such as those used to treat cataracts, can create visual distortions.

 

A new technology, however, now allows for the fabrication of lenses that refract light in the same fashion as the lens in the human eye.

Device to Improve Memory

Device to Improve Memory | Longevity science | Scoop.it

A study at North Carolina's Duke University has revealed that Stroboscopic training, the performance of physical activity while using eyewear that simulates a strobe-like experience, improves visual short-term memory for up to 24 hours.

Tiny robots in the eye may save patients' sight

Tiny robots in the eye may save patients' sight | Longevity science | Scoop.it

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.

 

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.

New technique to deliver stem cell therapy may help damaged eyes regain their sight | KurzweilAI

New technique to deliver stem cell therapy may help damaged eyes regain their sight | KurzweilAI | Longevity science | Scoop.it

University of Sheffield researchers have developed a new method for producing membranes to help in the grafting of stem cells onto the eye, mimicking structural features of the eye itself.

 

The technology has been designed to treat damage to the cornea, the transparent layer on the front of the eye, which is one of the major causes of blindness in the world.

Chemical found to temporarily restore sight in blind mice

Chemical found to temporarily restore sight in blind mice | Longevity science | Scoop.it

Researchers have discovered a chemical that makes cells in the retinas of blind mice sensitive to light, temporarily restoring some vision.

 

They are working on an improved compound that they hope could one day be used to restore sight in human patients suffering from retinitis pigmentosa, the most common form of inherited blindness, and macular degeneration, the most common cause of acquired blindness in the developed world.

Bio-Retina to enter clinical trials in 2013

Bio-Retina to enter clinical trials in 2013 | Longevity science | Scoop.it

At least 25-30 million people worldwide have age-related macular degeneration (AMD), one of the leading causes of blindness in middle-aged and older adults.

 

Israeli start-up Nano Retina has announced its new Bio-Retina, a tiny array of photodetectors which can be implanted directly on the retinal surface. Ready to enter clinical trials in 2013, the Bio-Retina restores vision to AMD sufferers almost immediately following the simple implantation process.
