Educational Interventions for Students with Low Vision
Approximately 90% of individuals with visual impairments have functional or low vision; just 10% are functionally blind. However, students with low vision are often an overlooked majority in the population of children who are visually impaired. Difficulties of students with low vision are often not as apparent as they are for students who are blind. Nonetheless, students with low vision require direct instruction in literacy, visual efficiency, accessing the core curriculum, compensatory skills and more. The following educational interventions are beneficial to students in any school setting. Teacher of Students with Visual Impairments
Every child who meets the criteria of visual impairment in his/her state is eligible to receive services from a certified teacher of students with visual impairments (TVI). A TVI is a teacher who specializes in working with students who are visually impaired. Most often, when a new student with a visual impairment enters a school system, it is the TVI who is responsible for assessing the student, determining and aiding in adaptations and modifications, as well as creating individualized education programs (IEPs). If the situation does not permit the TVI to perform all necessary specialized instruction with a student, the TVI will generally oversee or direct the instructional process. Accessing the Visual Environment
One of the principal concerns for students with low vision is their ability to access the visual environment. Just as students who are blind have difficulty with environmental cues such as facial expressions and eye contact, so too do students with low vision. One way for students to access the visual environment is through optical devices. Optical devices include magnifiers, microscopes, and telemicroscopes for accessing near information and monocular telescopes and bioptic lenses for accessing distance information. Near devices aid a child in viewing regular...
