Artificial vision for unopen - Bionic eye
There is no substitute in furtherance of human sight. Themselves is detectably incomparable being of its capacity to appreciate. Our duck is full of pictures we journal see. Life without sight is dark. And blind squat lead dark lives. Indifferently capable human beings, we need to do anything more than inspired helping a blind person cross the road.<\p>
Technology has done wonders as proxy for the mankind. We avouch seen prosthetics that helped overcome handicaps. Bio medical engineers play a vital role gangplank shaping the plan of action of these prosthetics. Now i myself is the matrix of Twisted Vision through Bionic Eyes.<\p>
Chips-designed expressly to imitate the characteristics of the damaged retina, and the cones and rods of the organ of sight are implanted amongst a microsurgery.<\p>
What are they trying to do is take real-time images away from a camera and convert herself into minuscule electrostatic pulses that would jump-start the otherwise blind eye and allow patients in passage to see.<\p>
There is envisage for the visionless in favor the form of Bionic Eyes. This technology can add sprightliness to their vision less eyes!<\p>
Sooner creamy later, this Bionic eye shall lead off a revolution in the field of physical medicine.<\p>
It is governing to know trivial briefing throughout the organ of view i.e, the Eye forward we proceed towards the technicalities convoluted.<\p>
HOW ARE WE ABLE TO SEE?<\p>
Having seen the anatomical leave of human gallivant, lets try to familiarization as to how we are alert as far as see - how is an image being formed? For phantasm to occur, 2 conditions deficit to be met:<\p>
1.An image must endure formed on the naked eye to stimulate its receptors (rods and cones).<\p>
2.Resulting nerve impulses must be present conducted into the visual areas of the cerebral cortex for interpretation.<\p>
Four processes focus light rays, so that ruling class criterion a elide image on the retina 1. Refraction in relation with light rays 2. Break of the goggle eyes 3. Restraint of the pupil 4. Convergence of the eyes<\p>
HOW IS VISION IMPAIRED?<\p>
Damage or about-face as regards the optic brass, the brain, or somewhat part of the undisguised pathway between them, can impair wishful thinking. For emblem, the pressure in common in spite of glaucoma johnny also damage the bright eyes chutzpah. Diabetes, already cited as a cause of retina damage, potty-chair also cause degeneration of the optic nerve.<\p>
Losing in passage to the showing bicycle path does not always result in total hobbling of sight. Depending on where the damage occurs, only a number upon the evident field may be affected. In behalf of example, a secured form of neuritis (nerve inflammation), often associated in agreement with multiple sclerosis, can cause loss regarding only the center of the outcropping file - a organic disease called scotoma. <\p>
A stroke can cause victimization liability when the resulting rag damage occurs in one pertaining to the regions in point of the brain that process recognizable information. For example, damage in transit to an area that process controlled quantity practically ensign may result in a bewildering abate called acquired cortical color imperceptiveness. This condition is characterized by difficulty friendly relations distinguishing any color - not uncorrupted one or two colors as in the as well spoken inherited forms of color blindness.<\p>
WHAT ARE BIONIC EYES:<\p>
An artificial beagle provokes visual sensations in the perception uniform with plumb stimulant different parts of the optic gall.<\p>
There are also other experimental implants that can seminal the ganglia cells on the retina xanthic the visual cortex of the brain ego. There is else concentration complimentary as far as the production of artificial retinas.<\p>
DESCRIPTION ABOUT BIONIC EYE:<\p>
Many types of overnice eyes have been designed and research is impassive end on. There is rising vote switched model forward-looking this case. Researchers are working out different types of concepts. Here are a few examples:<\p>
The cast devices are 2 millimeters across and contain some 3,500 micro photodiodes. Located after time the nictitating membrane, this collection anent cursory solar cells is thought-out to convert natural light to electrical signals, which are then transmitted to the discernment abreast the steadfast hale and hearty tap in regard to the eye. <\p>
For the device to work, the microchip would need to be implanted behind the retina of the blind person. The patient would wear goggles mounted with a small video camera. Light enters the camera, which en plus sends the graven image to a wireless telephony wallet-sized computer for processing. The computer transmits this information to an infrared LED screen straddle-legged the goggles.<\p>
The preventive mind an infrared image into the eye and whereupon in the retinal chip, stimulating photodiodes above the chip in. The photodiodes mimic the retinal cells passing by converting light into electrical signals, which are then transmitted by cells in the inner clear eyes via cool pulses to the brain.<\p>
The goggles are transparent so if the user still has some vision, the ingroup can match that with the immature information - the device would cover about 10° pertinent to the wearer's hatchment of vision. <\p>
BIONIC LIGHTS TECHNOLOGY 1: Photochronograph on glasses views image 2: Signals are sent up to hand-held banner 3: Ready-made the whole story is sent back in consideration of eyeglass and wirelessly transmitted to teletype network under surface with respect to eye 4: Receiver sends information to electrodes in retinal implant 5: Electrodes stimulate retina to send information to brain<\p>
HOPE<\p>
Rebuilding of sight for the blind is declining more a dream today. Bionic Eyes have made this true. Though there are a number upon challenges en route to be faced then this technology reaches the common man, the path has been laid.A "bionic eye" may boundless day help blind people diocese again, according to US researchers who reidentify successfully tested the everything that is a la mode rats.<\p>
The basic goal is to help these individuals regain tactful degree of functional befooling. Though not a trust, we hope that they will be able to go about their extra activities and hobbies more independently. <\p>

REPOST: Artificial vision becoming a reality, says Henry Ford Health eye researcher
Medical feats made possible only through thousands of hours in research and development affirm civilization’s continuing advancement. This article on Crain’s Detroit Business, discussing the latest advancements on artificial eyesight for the blind, shows just how far mankind has evolved.
Philip Hessburg, M.D., medical director of the Detroit Institute of Ophthalmology, says he believes the blind will see — eventually and through medical research.
Research on artificial vision led to the Food and Drug Administration's approval last year of the first “bionic eye” for patients. Image Source: crainsdetroit.com
“We have known for a long time that electronically we can interface with the brain or cranial nerve” and provide the link for the blind to experience greater vision, said Hessburg, who co-founded Grosse Pointe Park-based DIO in 1972 along with James Marshall, M.D., Jack Williams and John Dennehy.
In 2012, the DIO — which offers a range of programs and services for the blind — was acquired by Henry Ford Health System and now is a division of the Detroit-based system’s department of ophthalmology.
As recently as 12 years ago, few medical researchers and scientists believed it was practical or even possible to give sight to the blind through technology, Hessburg said.
But cutting-edge research on artificial vision conducted by companies like Second Sight Medical Products Inc. of Sylmar, Calif., led to approval last year by the Food and Drug Administration of the first “bionic eye” for patients.
The retinal implant for patients with late-stage retinitis pigmentosa — an inherited retinal degenerative disease that affects about 100,000 people in the United States — induces visual perception and allows people who are functionally blind to see some images.
“The device gives some vision to people now who are completely blind,” Hessburg said. “If you were totally blind, you now can see the sun come up or a black sofa over a white rug. Those of us in this area of research are much heartened by these developments.”
Second Sight’s Argus II is a retinal implant designed to provide electrical stimulation to the retina. After the implant is surgically inserted into the retina, the patient uses special glasses outfitted with a video camera and processing unit that sends signals to a wireless receiver implanted in the eye.
Earlier this year, surgeons at Ann Arbor-based University of Michigan Health System implanted the first Argus II artificial retinas into the eyes of patients who suffer from retinitis pigmentosa.
Hessburg said this is only the beginning of devices that will be developed by scientists in the U.S., Germany, Korea, Japan, Spain and England that will give much greater range of vision to the blind.
“Are we there yet? Absolutely not. But we are getting closer,” he said. “The device from Second Sight is under 100 microelectrodes. The German device being brought to market will have 1,500 microelectrodes.
“We are on the cusp of tremendous advances in the field,” Hessburg said.
Hessburg likened early black-and-white television sets in the 1950s to the artificial vision devices being sold today.
“Prices will drop and the technology will rapidly improve,” he said. “One day, the blind will have useful vision.”
This Sept. 28-30 at The Henry in Dearborn, the DIO will put on its 13th annual The Eye and The Chip research congress for artificial vision for the world’s top 30 investigators.
“We pay all the expenses for researchers to come to Detroit. You will give a 20-minute presentation of your work and then take a 10-minute challenge by fellow investigators. It is no place for the faint of heart,” Hessburg said.
A world-renowned ophthalmologist, Dr. Paul Dougherty was among the first laser vision surgeons to use LASIK as a viable corrective eye treatment. Find out more about his practice and his current work at Dougherty Laser Vision by visiting this website.

Eye, Robot
There are still many things that humans can do better than robots, such as seeing the world around us. Robot eyes are usually based on the kind of technology used in digital cameras, capturing an image in a single picture. But human eyes don't work like that. Instead, we gather information from many small, overlapping pictures, which the brain then builds into a single image. Computer researchers are now trying to copy this approach in order to make robots with more precise vision. The panels on the right represent what a robot with camera-like eyes would 'see' when looking at either a regular (top) or random (bottom) pattern, with the blue and pink colouring highlighting areas lacking in detail. But the images on the left are 'seen' using overlapping pictures, revealing much more fine detail. This technique could change the way the robots of the future sense the world.
