Bionic Eye
Bionic Vision Australia (BVA) is a consortium of world-leading Australian researchers, collaborating to develop an advanced bionic eye devices to restore a sense of vision to people with profound vision loss due to retinitis pigmentosa and age-related macular degeneration. A bionic eye mimics the function of the retina to restore sight for those with severe vision loss. It uses a retinal implant connected to a video camera to convert images into electrical impulses that activate remaining retinal cells which then carry the signal back to the brain.

The way it works is bionic vision system consists of a camera, attached to a pair of glasses, which transmits high-frequency radio signals to a microchip, implanted in the retina. Electrodes on the implanted chip convert these signals into electrical impulses to stimulate cells in the retina that connect to the optic nerve. These impulses are then passed down along the optic nerve to the vision processing centers of the brain, where they are interpreted as an image.
To benefit from this technology, patients need to have some remaining retinal ganglion cells, A healthy optic nerve and visual cortex, Very low or no vision, To have been able to see in the past, so that the vision processing part of the brain has developed fully, and a functional visual pathway from the retina to the brain along the optic nerve, as well as some intact retinal cells. As such, the two medical conditions that this technology aims to address are retinitis pigmentosa and age-related.
A person using a retinal implant to see will not experience vision in the same way a person with healthy eyes does. It will be quite basic to start with and they will need training to adapt to the implant. With time, training and patience, people will be able to use this visual information to be more independent and mobile. The retinal implant bionic eye works by stimulating the perception of light in a

    Our eyes are vital organs because they help us visualize our surroundings. But are our eyes perfect in seeing what’s right in front of us? Sadly I learned in our evolution, nature messed up at one point and gave us blind spots in our eyes. This project shows why we have these blind spots, how to discover them, and how big they are. I researched on how our eyes see things; why when one eye is closed, the other eye sometimes can’t see what’s in front of it. I also found during my research a formula that is used to estimate the size of a human eye’s blind spot. I performed an experiment using Blind Spot Test card I made to verify the existence of blind spots in my eyes. I also collected data while testing to find the size of my blind spot. I learned the size of eyes’ blind spots varies in relation to the size of the human eyes.…

    There are three distinct layers in the eye with the outer layer consisting of the cornea and sclera, the middle layer containing the iris, ciliary body and choroid and lastly the inner layer which has the retina (Galloway et al. 2006). The cornea’s main functions is to protect the eye against infection and to refract and transmit the light to the lens and retina. The iris controls the size of the pupil, thus limiting the amount of light that reaches the retina. The ciliary body controls the shape of the lens and the choroid provides nutrients and oxygen to the eye. The retina contains neurons that capture and processes light. Light enters the eye via the outer components and travels through the neurons of the retina and is accordingly captured by the photoreceptors present at the back of the retina. The neurons then translate the visual information received from the eye into nerve impulses that travel from the optic nerve to the lateral geniculate nucleus to be interpreted (Willoughby et al. 2010). Each eye sees a marginally different image which is combined in the brain to become one…

    Vision starts with light, the physical energy that stimulates the eye. Light waves coming from some object outside the body are sensed by the eye; the only organ that is capable of responding to the visible spectrum. Eyes convert light to a form that can be used by the neurons that serve as messengers to the brain. The neurons themselves take up a small percentage of the total eye. Most of the eye is a mechanical device that is similar to a traditional, non-digital electronic camera that uses film.…

    Learning about how visual impairments take place must not be noted until we find out how a person can see. There are three functions for seeing: optical system, muscular system, and the nervous system, all play a role in how a person uses their vision. According to the IDEA, (Individuals with Disabilities Education Act), any human being whose vision is 20/200 or less is considered legally blind (Heward, 2013). The educational definition when referring to learning states, an impairment in vision that disrupts a child’s ability to succeed in educational performance. Damage to the optical, muscular or nervous system can cause a visual impairment. Types of visual impairments include cataracts, color blindness and glaucoma. When it comes to academic achievement students will not be left behind when it comes to visual impairments. For students who are blind the use of braille is the way of reading and writing in which letters numbers and words are in arrangements of raised dots on the book or paper. Computers have special keyboards for students with visual aids so that the use of technology is not taking away from the student. Students with low vision have the options of optical aids where magnification plays a huge role in helping the student see.…

    The Argus II is also known as the bionic eye. The bionic eye basically involves the doctor to place an artificial retina, which has a chip that would connect to the glasses. The glasses have wireless powers that can translate signals into vision. When you see these glasses you can tell there’s a lot going on. The glasses have an antenna, camera, and a video processing unit or VPU connected to it. There are three steps to how this all works. The camera takes a picture, which is then processed into electrical impulses, and then the impulses are directed to the chip through the wireless receiver. The signals are sent to the optic nerve in the brain. The cells that haven't been damaged by the eye disease are stimulated by the pulses, which then allows the brain to catch light…

    Sight plays a very important role in the experiences one may undertake in his or her life. We use sight every day, to see the people we love, to eat, to pick out what outfit one might choose to wear for the day, and much more. Vision and the aspect of using this sense as way to learn is significant when it comes to making memories. Loss of sight is a struggle to many people and although science may have had some advantages to help people with loss of sight and restore their vision; The unfortunate fact is that these visual impairments may be fixed with no connection to brain processing treatment, which can cause sensory disorders. Infact, many studies show that researchers have undergone multiple number of experiments to furthermore, better…

    A more ambiguous reason for genetic engineering is the elimination of common defects that vary in seriousness, such as sensory impairment. Dozens of chromosomes linked to hearing impairment have been located (Ruben, 33). Although treatment for such conditions initially looks promising, as the elimination of complete blindness or deafness would alleviate hardships caused by these disabilities, removing serious sensory conditions and actually raising sensory ability to a level above normal are separated by a fine line.…
