Artificial Sight by Mark S. Humayun,James D. Weiland,Gerald Chader,Elias Greenbaum Pdf
This book describes advances in implantable neural stimulation technology to restore partial sight to people who are blind from retinal degnerative diseases such as age-related macular degeneration and retintis pigmentosa. Many scientific, engineering, and surgical challenges must be surmounted before widespread practical applications can be realized. The book summarizes the state of research and clinical practice in the field and reviews the current ideas and approaches of its leading researchers and practitioners.
Jens Naumann, a typical energetic young man of 17 had just moved out of his parent’s home in Northern British Columbia, moving into a railway camp as an employee with the British Columbia Railway. All goes well as Jens enjoys his new found freedom, treasuring his driver’s license and its associated freedom of travel. Then on a wintry day in 1981, fate rears its ugly head and strikes him blind in his left eye. Jens quickly rearranges his life to accommodate his new found fear - that of losing his remaining eye now that the true vulnerability of his eyesight is revealed. As his life continues onwards despite the initial readjustment, he finds ultimate happiness in his new marriage to his young wife Lorri, and just when life stands at its threshold of paradise exploring fatherhood along with the beauty of travel and thrill, his worst nightmare becomes reality not once, but twice in the most bizarre series of unforeseen incidents of bad luck; as Jens is totally blinded with no foreseeable chance of seeing again according to the best medical experts. Jens tries his best to adjust to this unwanted situation, exploring conventional methods of rehabilitation to live with blindness, as well as using imaginative, totally unheard - of activities in order to pass his time in a hope of someday being able to see again despite all the odds stacked against him. Close to the turn of the century, Jens unexpectedly receives news of an American Medical Device Engineer, Dr. William H. Dobelle, inviting blind adults as patients for his newly developed artificial vision system designed to provide limited vision via visual cortex stimulation. Dr. Dobelle claims that his system has a good chance in functioning based on previous experimenting with volunteers, at the same time classifying the surgical procedure as minor. The system and its related components is complicated; consisting of not only the implants, but a series of “electrical sockets” protruding from the patients head to which an array of computer boxes and stimulator hardware is connected and worn by the patient. Jens is determined to be one of the patients, regardless of the remoteness of the chance of being one out of literally millions of blind people in the World possibly lining up to have this procedure in hopes of ending their blindness for once and for all. To his absolute surprise, Jens is accepted as the first patient for this procedure and slowly builds a relationship with Dr. Dobelle as Jens overcomes obvious barriers of raising enough money for the very expensive procedure, as well as fighting the challenges of relentless forces working against him for his involvement in the Dobelle vision project. Armed with preconceived ideas of how a research institute should be run, Jens travels overseas for the various stages of the procedure, only to find the most astonishing facts of what goes on in the heart of a renowned medical research institute. Not only is Jens looking at the workings of the Dobelle Institute from the view of a patient, but in short time Jens is hired by the firm as Patient Representative, providing further exploration yet on the inner most details concerning a research company and its treatment of the 15 additional implanted patients. Throughout the book, Jens describes the devastation, exhilaration, disappointment, elation, and confusion that attempts at sight recovery, medical intervention, media propaganda, and ethical boundaries conjure in the most illustrative intensity. The manner in which the book ends is most indescribable; one could view it as the final straw, the beginning of a new era, the curse of the unforgiven, the sadness of a crushing reality, the beginning of a good job left unfinished; or that of the birth of a new expert compelled to unleash the new found knowledge for the whole World to thrive. Just as many questions are answered, many more yet are opened and left so far undiscovered. Search for Paradise is ce
My Brain Implant for Bionic Vision by Richard B McDonald Pdf
This book tells the true and amazing story of being a participant in the first trial of a brain implant for bionic vision. Blind for 13 years, the author relays why he volunteered in 2018 for the experiment. Discussed are the grueling process of qualifying to be accepted into the trial and the stunning nature of this real bionic technology. Detailed descriptions of the resulting synthetic vision are given. Also described are the amazing "bionic laboratory" and the process of learning to see again with bionic eyesight. The book also discusses the tricky ethical considerations about bionics and the increasing merging of humans with machines. It concludes with what the future holds for bionic vision.
I Sight: The Power of Perception By: James Eliol Mercer Harrowing and deeply personal, I Sight: The Power of Perception is a memoir detailing the journey of author James Mercer as he comes to the realization that he suffers from a rare genetic eye disorder, one that deteriorates with time and threatens to leave him fully blind by middle age. Starting in early childhood, Mercer recognizes he is different from his peers; his parents never let him stay out past sundown, and often in low light or bright light conditions, the world becomes an indecipherable blur. With adolescence comes a better understanding of his sight deficiency, but it also creates a greater divide between Mercer and other “normal” teenagers, who can freely go to school dances and to local nightly hangouts, getting to experience a freedom Mercer may never know. This memoir tells a story of how disability can bring fear, shame, and isolation, but through the love of family and true friends, one can find acceptance and joy.

Sir Harold Ridley and His Fight for Sight by David J. Apple Pdf
Did you know that the most common surgical eye procedure today began as a tragic injury to a WWII pilot? Did you know that one of the first medical devices to ever be implanted into a human was performed by an ophthalmologist? Do you know the riveting story behind the man who envisioned and achieved ground-breaking medical advancements for vision care? ______________________________________________________________________________ An innovator in eye surgery and undisputed inventor of the intraocular lens (IOL), Sir Harold Ridley achieved some of the most important discoveries in ophthalmology and medicine over the last 100 years. The compelling story of Sir Harold Ridley is one not widely known among today's medical community. It is a story of an unassuming medical leader. It is a story that needs to be told, not only for its historical value, but also to provide guidance for future generations on bringing new inventions to the world. In the early 1980's, Dr. David J. Apple, one of the most prominent American ophthalmologists and eye researchers conducted studies that by the mid-1980's had verified that Ridley's innovation--the implantation of the IOL--was potentially safe and effective. Upon hearing of these studies, Ridley requested to meet Dr. Apple at Ridley's home in England, where a life-long personal and professional relationship was born. Inside Sir Harold Ridley and His Fight for Sight: He Changed the World So That We May Better See It, Dr. David J. Apple chronicles the amazing career and life of Sir Harold Ridley based on their friendship and on never before published documents, photographs, and memorabilia. Ridley's tremendous impact on ophthalmology and specifically on the treatment of cataract patients, is a story that until now has not been told. Sir Harold Ridley and His Fight for Sight is based on 26 years of research performed by Dr. Apple. Interviews with friends, families, colleagues, as well as the review of medical and hospital records, military records, and museum exhibits have brought the story of Sir Harold Ridley to forefront of the medical community today. Dr. Apple brings life and credibility to the pages of Sir Harold Ridley and His Fight for Sight with over 600 images, testimonials from Sir Harold Ridley on his quest that began in 1935, and a personal touch that only a true colleague and friend can convey. From Harold Ridley, 1989: "I had twenty-five years in the wilderness and would have been spared much suffering if David Apple, the one who at last took the trouble to read and analyze all the early implant papers, had appeared in the 1950's, for a whole generation of cataract patients might then have enjoyed full visual rehabilitation instead of suffering the abnormalities of aphakia." In 1940 during World War II, in the legendary Battle of Britain, a British pilot was tragically blinded when shattered fragments of his cockpit canopy were embedded in his eyes. This tragic event led to the identification of an implant material and eventuated in Ridley's accomplishing a complete cure for cataracts. Ridley focused the next decade of his life on the development of an artificial lens to be implanted following the removal of a cataract. This device has restored vision to nearly 200 million people worldwide, and presently 9 million annually. After performing the first IOL implant on a cataract patient, Sir Harold Ridley was met with opposition from the medical community. It took three decades of struggle until his goal became reality. Now the cataract surgery, and its cousin, refractive surgery, including the procedure LASIK, are the most common surgical procedures performed today. Paving the way for past, current and future ophthalmologists, Sir Harold Ridley not only implanted the first medical device into a patient--he pioneered multiple once in a lifetime discoveries including innovations on river blindness, techniques for optic nerve and retina diagnosis, introduction of television and other electronic techniques to ophthalmology, as well as establishing a branch of biomedical engineering focusing on the science of artificial implants. Sir Harold Ridley and His Fight for Sight is the story of a brilliant man and his lifelong struggle to gain acceptance for his invention from his peers. He finally achieved this late in life and the intraocular lens is now recognized as one of the most important medical advances of the 20th century.
This elegantly written book offers an unexpected and unprecedented account of blindness and sight. Legally blind since the age of eleven, Georgina Kleege draws on her experiences to offer a detailed testimony of visual impairment—both her own view of the world and the world’s view of the blind. “I hope to turn the reader’s gaze outward, to say not only ‘Here’s what I see’ but also ‘Here’s what you see,’ to show both what’s unique and what’s universal,” Kleege writes.Kleege describes the negative social status of the blind, analyzes stereotypes of the blind that have been perpetuated by movies, and discusses how blindness has been portrayed in literature. She vividly conveys the visual experience of someone with severely impaired sight and explains what she can see and what she cannot (and how her inability to achieve eye contact—in a society that prizes that form of connection—has affected her). Finally she tells of the various ways she reads, and the freedom she felt when she stopped concealing her blindness and acquired skills, such as reading braille, as part of a new, blind identity. Without sentimentality or clichés, Kleege offers us the opportunity to imagine life without sight.
1967 Here is a book which teaches you how to regain these by natural methods, many have benefited. Contents include: Eye Exercises, Facts and Theories about Sight, the Mind and Sight, Health Vigor and Sight, Light and Sight, the Ear and Sound, etc.

From its inception in Greek antiquity, the science of optics was aimed primarily at explaining sight and accounting for why things look as they do. By the end of the seventeenth century, however, the analytic focus of optics had shifted to light: its fundamental properties and such physical behaviors as reflection, refraction, and diffraction. This dramatic shift—which A. Mark Smith characterizes as the “Keplerian turn”—lies at the heart of this fascinating and pioneering study. Breaking from previous scholarship that sees Johannes Kepler as the culmination of a long-evolving optical tradition that traced back to Greek antiquity via the Muslim Middle Ages, Smith presents Kepler instead as marking a rupture with this tradition, arguing that his theory of retinal imaging, which was published in 1604, was instrumental in prompting the turn from sight to light. Kepler’s new theory of sight, Smith reveals, thus takes on true historical significance: by treating the eye as a mere light-focusing device rather than an image-producing instrument—as traditionally understood—Kepler’s account of retinal imaging helped spur the shift in analytic focus that eventually led to modern optics. A sweeping survey, From Sight to Light is poised to become the standard reference for historians of optics as well as those interested more broadly in the history of science, the history of art, and cultural and intellectual history.
