Visual Impairment
Introduction
Vision challenge or impairment is when a person’s degree of seeing is very low and the affected person requires assistance in order to carry out daily routine. Significantly, for one to qualify as visually impaired there must be prove that a person cannot undertake duties by himself without necessary assistance. For a person to qualify as a visually challenged, there must be a prove that the affected eyes cannot be conventionally treated. Visual challenge cannot be corrected by surgery, refractive measures neither by medication and that is why it is termed as visual impairment. The most rampart causes of visual challenge are trauma, degenerative or congenital means and a variety of diseases. In the society, blindness is the term that is preferably used to describe a visually impaired per son. Low eyesight is generally revealed when the affected person cannot view a normal distance and walk by himself (Algozzine, 2006). The degree of impairment can also be revealed when a person cannot read some normal writings. This is to say that even with the assistance of contact magnifying glasses or even eyeglasses the victim cannot reveal the writings on a normal newspaper (Bailey & Hall, 1990). Hyperopic impairment is accrued with inability person to see objects in a close distance. Myopic impairment is quite the opposite of hyperopic whereby a victim cannot identify objects at close distance. All these vision challenges greatly obscure the affected person from comfortably carrying out the normal daily routines without being assisted. According to Bailey & Hall (1990), vision challenged persons normally have to use other physical senses in order to carry out duties. A very blind case reveals that the victim can only use or learn by using non-visional procedures or the Braille. When it comes to the legally confirmed blind, the affected

The essay will also go into detailed by supplying a lesson plan which will include the objectives/goals, accommodations/modifications, strategies, assessments, activities as well as including brief description of the student by submitting the student’s age, grade, disability strength, and weaknesses. Hearing and Visual Impairments Hearing is a complex process of changing sound waves into the neural signals which can be translated by the brain into sounds. Within the inner ear is the Cochlea, which changes sound waves into neutral signals. The signals are sent to the brain through the auditory nerve. Where the visual impairment is also a complex process, light enters the eye through the pupil and is collected by photoreceptor neurons in the retina. Signals are then sent to a neuron network that then generates electrical impulses which goes to the brain. The legal definition of a hearing impairment is “a full or partial decrease in the ability to detect or understand sounds. It can range from a mild hearing loss to total deafness” (Hearing Impairment Law...

Assistive Technology

...Twenty-first century teachers and librarians work with students and/or patrons with disabilities on a daily basis. One example of an assistive technology device that can be used for students with disabilities is audio books or digital books. Audio books are excellent resources for anyone who cannot read due to a learning disability, dyslexia, or visual impairment (Ruffin, 2012). Students and library patrons, no matter their age, can follow along in the text while listening to the book on tape, CD, or any other digital AT device. Although tapes and CD’s are somewhat dated, MP3 files and other online audio material are not, and these are readily accessible for students. The great thing about audio books is that one no longer has to rely on a cassette player or CD player in order to gain access. It is easy to access them using an iPad, iPod, laptop, Nook, Kindle, or even a smart phone. The cost of audio books is not cheap; however, some can be downloaded for free. There are some digital audio books that cost less than the physical text and can be installed on any device that plays digital audio. This allows those with visual impairments or those with dyslexia or other reading disabilities an ability to comprehend not through sight, but through hearing. Audio books help with intellectual barriers by helping students have the same benefits as their peers. Students with reading and sight disabilities are able to have the same...

What Diversity Means to Me

...asked me questions about what it was like to live in an area that was so diversified. It was hard to believe that even in this era the people of this town seemed to be so secluded and seem to have no idea about other races or cultures. There was not much diversity in this small town, therefore they seemed to be only educated about what they knew. I believe education is the key when it comes to accepting those who are different than us. I not only grew up with many cultures in Indianapolis, but I knew people with different types of disabilities. I am visually impaired due to diseases called Glaucoma and Iritis (Arthritis of the eyes). I went to school at the Indiana School for the Blind. Every student at this school had some kind of visual impairment that varied...

Task 2

...educational resource that I chose was a video though Kahn academy. I chose this because not only do the students watch a video about third grade math they have to work a few math problems. This educational resource is appropriate for most of the student population. The video is for third grade math so that makes it appropriate for early childhood. The video gives gradual instructions with visual aids, which can help students who have learning disabilities. The videos on Kahn academy are appropriate for gifted and talented students because the video is based on what the students is learning and what they know. This video is appropriate for students who have challenging behaviors because the video is active and can keep a students interest. The video is appropriate for English language learners because on the website you can choose a variety of languages to hear it in. The video on third grade math warm ups is not appropriate for students with hearing impairments because it does not have closed captioning as an option. The video was not appropriate for students with visual impairments because the video shows different math activities in step-by-step instructions. If a student cannot visually see the steps, I am not sure that the video will help them. Overall, I think that the Kahn academy video would be appropriate for most of the students. The second educational resource that I chose was the Scholastic website as a multi media file. This site has...

...VISUAL IMPAIRMENTS describes a wide variety of conditions that affect vision abilities. We use the term to denote mild to most severe vision loss, rather than to defects in the eye itself. According to the Individuals with Disabilities Education Act (IDEA) of 1997, a visual impairment refers to “an impairment in vision that, even with correction, adversely affects a child’s educational performance. The term includes both partial sight and blindness.” Degrees of Visual Impairment: * Totally blind. This term usually implies little or no visual sensitivity to light at any level. This condition is rare, and people who are totally blind typically have severe physical damage to the eyes themselves or to the visual nerves. * Legally blind. A legally blind person has a visual acuity of 20/200 or less in the better eye, after correction. This means that what an individual with normal (20/20) vision sees at two hundred feet, the legally blind person cannot see until he or she is within twenty feet. In addition, a person can be classified as legally blind if she has a field of vision no greater than twenty degrees at the widest diameter. (A normal field of vision is close to 180 degrees.) Only about 20 percent of legally blind people are totally blind. Legally blind individuals typically use Braille and visual aids. * Low vision. People with low vision can read with the help of large-print reading materials and magnifying objects. They may also use Braille. * Partially...

Specialty Groups

...make a difference. As a human service professional, parents of children with visual impairments are a target group that I want to focus on. Visually impaired children have special needs and concerns which are unlike other disabled children. Becoming parents of a child with visual impairments, it was extremely difficult finding the necessary support groups to help us through difficult situations. Within this paper I will discuss the roles of a human service workers when facilitating a group for parents with visually impaired children, explain the theoretical approaches used in such groups, and the ultimate goals for the group. Parents normally take the necessary precautions to ensure that their child is as healthy as the child must be. The advancements in medical technology and testing assist medical providers in predicting possible medical conditions in unborn children. Though there are congenital defects that are not detected in serological testing and cause’s impaired vision in children. Parents who birth to a child with visual impairments experience the stages of grief and having a support system can be very comforting. Hosting a group for parents that are experiencing grief related to their child’s vision disorders eases the feeling of isolation during this delicate period. The purpose of the group is to remove the negative stigma that is associated with children with visual impairments, realize that there are solutions for parents, expand on possibilities for both...

...talking. It could also make it harder for the people who actually want to listen. This would mean that the people listening would not get the important message that was being said to them in the presentation. If was something important for example like a new system is being out at work the employees then would not know this information. A way to reduce this is before speaking or doing presentation the person presenting makes sure that everyone is silent and warn the people they are presenting to that this is crucial information you are about to be told. Additionally they could stop every time a person talks over them so the person gets embarrassed which could stop them doing it again. * Stuttering or speech impairment; Having a stutter or speech impairment creates a barrier for communicating because the person who you are talking to may find it hard to understand what you saying if you continually stutter. For example in the workplace if the manager had a stutter and when if had a conversion with you the employee about your performance in work and he was telling what and how to improve within work, but kept stuttering and then you left the conversion by not understanding a word he just said. This would be bad within the workplace because you...

...Devices and Practices for Sensory Impairments Devices and Practices for Sensory Impairments Every child, regardless of whether they have disabilities should receive a quality education. Those children with sensory impairments such as blindness or deafness should not be excluded from others as their impairments can be facilitated with the ever evolving technology and devices that are currently available to help those with these impairments. These devices are able to aid those with visual or hearing impairments and contribute to providing them with the quality education they deserve. They provide children with these challenges with a way for them to better participate in activities and lessons in ways to help keep them on the same level of understanding as other children who do not have these challenges. Two specific devices that help children with hearing and visual impairments are hearing aids and visual aids. Hearing aids have been around for a very long time and are commonly used by both children and adults who experience hearing difficulties or deafness. As technology evolves, hearing aids are less bulky, more comfortable, and simpler to use than older models. A hearing aid provides the wearer with the ability to amplify sound and are equip with volume control and are powered by batteries. A hearing aid is offered to those who have been examined by an audiologist and it is found that hearing impairments are present. The audiologist will then determine...

Therapeutic Communication Nursing

...Communication and Therapeutic Relationships in Nursing/Midwifery A therapeutic relationship can be described as one that offers support and care without being judgemental and can provide trust and a feeling of safety from threatening situations(Mc Klindon et al1999). In contrast to a social relationship it differs greatly in that a therapeutic relationship consists of collaborated goals which are identified when the relationship is initiated and once these goals are fulfilled the relationship is terminated in a therapeutic way(Nurses Association of New Brunswick2000).There are many communication techniques that can prove to be useful in certain situations for example verbal and nonverbal communication as well as being aware of body language and tone of voice which can benefit the therapeutic relationship. It is essential to learn how to be assertive as it can promote fairness and efficiency at work(Hodgetts 2011). One must learn how to communicate effectively with clients from different cultures who speak different languages in order to ascertain the clients needs and in order to build the therapeutic relationship. Developing a Therapeutic Relationship In order to develop a therapeutic relationship it has been found that a number of skills are required for example conveying empathy and understanding, accepting individuality, providing support, promoting equality, demonstrating respect, maintaining boundaries, self awareness and being there for the client in a genuine manner(Dziopa...

Exceptional Children

...above) to such an extent that they require an individualized program of special education and related services to fully benefit from education. The term exceptional children according to Heward, W. L. (2006 ) includes children who experience difficulties in learning as well as those whose performance is so superior that modifications in curriculum and instruction are necessary to help them fulfill their potential. Thus, exceptional children is an inclusive term that refers to children with learning and/or behavior problems, children with physical disabilities or sensory impairments, and children who are intellectually gifted or have a special talent. Although the terms impairment, disability, and handicap are sometimes used interchangeably, they are not synonymous. Impairment refers to the loss or reduced function of a particular body part or organ (e.g., a missing limb). A disability exists when an impairment limits a person’s ability to perform certain tasks (e.g., walk, see, add a row of numbers) in the same way that most persons do. A person with a disability is not handicapped, however, unless the disability leads to educational, personal, social, vocational, or other problems. For example, if a child who has lost a leg...

The blind have many challenges which must be faced on a day-to-day basis, and it is the job of the counselor or human service worker to work with the client to help him or her overcome these challenges. In this paper areas of special problems and needs of the blind, barriers in delivering the services to these clients, and solution which will help these clients overcome the barriers they face will be reviewed.

...[pic] Resolution of the World Health Organization After meeting in Geneva in May 2003 for the Fifty-Sixth World Health Assembly, the WHO outlined its Global Initiative for the Elimination of Avoidable Blindness, or VISION 2020 plan. The WHO urges national governments to: • Set up, not later than 2005, a national VISION 2020 plan, in partnership with the WHO and in collaboration with NGOs and the private sector. • Establish a national coordinating committee for VISION 2020 or a national blindness prevention committee, which may include consumer or patient groups, to develop and implement the plan. • Commence implementation of such plans by 2007 at the latest. • Include effective information systems with standardized indicators and periodic monitoring and evaluation, with the aim of showing a reduction in the magnitude of avoidable blindness by 2010. • Mobilize resources for eliminating avoidable blindness. In turn, the WHO agrees to: • Maintain and strengthen the WHO’s collaboration with governments and all partners of the initiative. • Ensure coordination of the implementation of the VISION 2020 plan, by setting up a monitoring committee grouping all those involved, including national government representatives. • Provide support for strengthening national capability, especially through development of human resources, to coordinate, assess, and prevent avoidable blindness...
