In 1974 ABC Network aired the The Six Million Dollar Man whose protagonist was severely injured in a plane crash, sustaining life threatening injuries inclusive of his left eye destroyed by metal fragment. His injuries made him the perfect candidate for ground breaking technology and he was fitted with a bionic eye, which allowed him telescopic and microscopic sight along with night vision capabilities. Although the bionic eye and its capabilities was part of a science fiction series at the time, today, forty years later the bionic eye is a reality, which is able to restore vision to the blind, but its recipients will not be able to see like the Six Million Dollar Man (Bionic Wiki, n.d.). Two decades ago the development of a bionic eye was …show more content…
The implant is comprised of a coil and a case, which are placed around the eyeball using a scleral band, and an electrode array, which is tacked intraocularly on the surface of the retina. • Argus II Glasses: Glasses that are specially fitted with a miniature video camera, radio-frequency (RF) coils and associated electronic circuitry. The glasses transmit electrical stimulation data along with power via telemetry to the implant. The Argus II Glasses are worn by the patient. • Argus II Operating Room (OR) Coil: An RF coil that is used to test the functionality of the implant during the implantation procedure. • Argus II Video Processing Unit (VPU): A battery-powered device that processes the video signal obtained from the video camera on the glasses and transforms it into electrical stimulation data. The electrical stimulation data and power are then sent to the Argus II Glasses for transmission to the implant. The VPU comes with a pouch that is worn by the …show more content…
“Images from the camera are converted into a series of electrical pulses that are transmitted wirelessly to an array of electrodes on the surface of the retina. The pulses stimulate the retina's remaining healthy cells, causing them to relay the signal to the optic nerve. The visual information then moves to the brain, where it is translated into patterns of light that can be recognized and interpreted, allowing the patient to regain some visual function” (Press, 2014) The Argus 11 provide a "pixilated type of vision." "The patient essentially has to try to determine what those flashes of light mean, and in many cases it can help them determine where a window is, light coming in through the window or where a doorway is, essentially help them navigate the world around them." (Firger,
Optometrists have accepted vision therapy, which is a medical treatment for optical muscle disabilities, as a feasible treatment used for eye related problems; claiming the treatment can strengthen vision and give the patient the opportunity to understand visuals quicker and clearer (Press). Vision therapy originated in the 1950s and over the past 25 years, has gained popularity, mainly because of new technological innovations in the field of treatment. Generally, vision therapy is prescribed as a measure mainly for people between the ages of 3 and 18. With the results from a comprehensive series of eye tests, the optometrist can work with the patient using special instruments—prisms, filters, occluders, and eye lenses—and strengthen the eye muscles, thus improving sight. According to optometrists in favor of vision therapy, these methods of treatment using these instruments function as safer routes to repair eye disabilities. Although vision therapy can yield favorable results, the practice as a treatment for innate eye disabilities has been in hot debate lately; as it can exceed $8000 and insurance companies do not cover the treatment. For decades, insurance companies have refused to accept vision therapy as a legitimate method for repairing eyesight (Boink). Concomitant with lack of insurance, the cost for a full treatment can exceed $8000, and doctors cannot guarantee a successful outcome. Recently, parents of children with eye related disabilities, such as amblyopia (lazy eye) and strabismus (cross-eye), and doctors have attempted to cooperate with public schools to allow families access to school-funded doctors to practice vision therapy. With a tight budget, most schools cannot afford to supply vision therapy, and a...
When the operation begins, Dr. Todd will use a steady hand to make a small opening in the side of the cornea. To begin removing the cataract, she switches tools and uses a vibrating ultrasound device to break the hard, cloudy lens into smaller pieces. Following this, she will suction the fragments out through the small cut in the eye. After the cataract is removed, she will begin to insert the intraocular lens in place. This is called an intraocular implantation. This lens is permanent, clear, and will restore normal vision for the patient.
Cochlear implants are electronic devices that sends signals directly to the auditory nerve. Cochlear implants consist of external parts which include the microphone, speech processor, and the transmitter. They also consist of internal parts that must be surgically placed under the skin including the receiver and electrical array. In order for the implant to work, the microphone
5) Use of an Eye-Operated Eyegaze Communication System in Locked-In Syndrome, by: James E. Chapman, M.D.
During my childhood I was diagnosed as having poor eyesight and was prescribed glasses to assist with my vision correction. I realize how blessed I am to have had that as an option. I was always in awe of the environment and creatures who inhabited the various areas of nature. The sense of vision is very important and without the ability to see an individual would be missing out on many colorful life experiences. Blindness, which is the lack of the ability to see is a very dark and challenging disability. Without one’s eyes, everyday activities such a walking, reading, eating and identifying people can be a struggle. It has been proven that the brain will adapt to the loss by giving itself a makeover. If one sense is lost,
Blindness affects more than one million Americans (Marcovitz 6). Experts say more than two-thirds of blindness can be avoided through timely prevention or treatment (7). An estimated amount of three-hundred million people will suffer from blindness by 2020. Ray was born on September 23, 1930 in Albany, Georgia. (Sloate 8). At age seven Ray starting losing his eyesight more and more every day. When Ray woke up one morning he could not open his eyes so his mom, Aretha, took him to a clinic. The
My father made a successful recovery and I became inspired. I realized that having the gift of sight is something people take for granted. Therefore, when I embarked on my undergraduate journey, I partook in several activities to help foster my thirst for knowledge about optometry. For instance, I became the treasurer of the pre-optometry club at the University of Florida. As an executive board member, I opened doors for others to find their passion for optometry through managing our budget and finances to sponsor trips and activities. Meanwhile, I also worked as a secretary and shadowed at the Eye Associates of Orlando, where I gained practical knowledge. I also volunteered for the KidSight Vision Screening Program where I entered data of visio...
Many times, people are left with an impaired brain for the rest of their lives and that damage can extend from being unable to control a limb to damaged eyesight to major memory loss. The purpose of implants is to aid the damaged portion of the brain to eradicate the symptoms that are associated with these serious brain disorders. Implants are inserted in the section of the brain that is impaired, whether it is the frontal lobe to help motor skills or in the occipital lobe to aid
Until recently, those affected were left without hope of a cure or even a treatment that would somewhat improve their vision. But over the last few years, several groups of scientists have been working on a partial cure in the form of neuroprostheses, artificial devices which are inserted into the eye behind or on top of the damaged retinal area. These photoreceptive chips, in theory, should provide information to the healthy neurons residing in the retina, substituting for the damaged photoreceptors. When we open our eyes, millions of tiny events occur that allow us to see. Our pupils automatically constrict in accordance to the light level, the variable lens bends and adjusts to fit the distance of what we are looking at, and our photoreceptors receive information in accordance to the previous factors.

Life revolves around being able to see things. Although individuals who are blind can lead a full and happy life, someone with excellent vision who suddenly loses theirs or notices a decrease in their visual acuity over time may find it difficult to adapt. Thankfully, with the help of an optometrist, individuals can actively work to preserve their vision for as long as possible. Phoenix Eye Care must be a priority for all, as advanced technology allows threats to the eyes to be detected at the earliest stage. The right treatment can help to slow or stop the progression before major issues develop.
LANDBACK, also known as #LANDBACK, is a term used to describe a campaign driven by Indigenous communities and allies of the movement who seek to reestablish Indigenous sovereignty across North America and other regions worldwide by addressing historical injustices to Indigenous peoples and reclaiming ancestral lands. LANDBACK stands for the reclamation of control over lands which have belonged to Indigenous peoples, lands that are currently occupied and reigned over illegally. Along with the reclamation of lands dispossessed through colonisation, LANDBACK aims to return stewardship of lands to Indigenous communities, reinvigorate Indigenous practices and culture, provide Indigenous leadership in environmental implementations, educate societies

When the contact lens was invented, the world of vision correction was altered forever. No longer were those people lacking perfect 20/20 vision forced to look any different than everyone else. Both discrete and revolutionary, the contact lens provided a brand new, viable, alternate solution to an age-old problem. After centuries of engineering and discovery the contact lens has evolved greatly. Presently contact lenses are made hard or soft, for daily or continuous wear, gas permeable, and even providing ultraviolet protection. A properly fitted pair of today’s discrete, convenient, versatile, and inexpensive contact lenses provide the best form of vision correction available in today’s market.
