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 person has slightly low vision of up to 20/200 sight capability. As it is revealed by all these cases, eyesight impairment is not necessarily a disorder, but an impairment that requires procedural measures to take good care of the affected rather than seeking for some medication. In most cases, nerve complications can cause blindness and mostly if these complications can reach the brain, a disorder known as CVI (Cortical Vision Impairment) is developed (Bailey & Hall, 1990). In addition, other eye complications can result to visual challenge. Eye infections, diabetic complications, glaucoma, congenital disturbance, congenital complications, albinism, cataracts and cornea complications are the most possible causes of visual problems. Due to the many incidences of blindness, there is need for relevant government agents to establish ways of assisting the affected population (Algozzine, 2006). When the blind are educated to be independent, there are reduced cases of dependency and hence the blind can contribute to economic growth. Characteristics
Visual challenges are exhibited in various ways. Understanding the character of visual challenged person or child will greatly help in enacting ways of helping such. In the case of visually impaired students, different learning institutions will categorize the eyesight-impaired kids according to the severity of the challenge. Intellectually, the visually impaired students is at par as the sighted students. When visually impaired students undertake tests through auditory-vocal as well as other communication channels that support visually impaired students then the academic achievement of such students is assured. However studies indicate that visually impaired students do not score well in Mathematics. Visually impaired students have particular behavioral disparities. Firstly, when the child is taken to a new environment, the episodes of clumsiness are exhibited (Fan & Cheung, 2005). Such a student is in constant communication with their colleagues as they seek to get clarifications on goings. The student usually remains...
