Visual Impairments (VIs) are ranked as the fourth most common disability in the United States and are viewed as the most common restricting condition during childhood. It has been reported that 17% to 25% of school-aged children have some degree of a vision problem, thus interrupting their potential to reach optimal growth and learning in school.…

THE FOLLOWING IS THE FULL TEXT OF THIS DOCUMENT: Video visual aids are Closed Circuit TV systems (CCTV's) which magnify print and enlarge it electronically upon a screen so partially sighted persons with some residual vision can read and write normal size print. These devices are in use around the world in homes, schools, industries and libraries,…

Five considerations for determining the most appropriate learning medium for students with functional vision are: (1) working distance from the page; (2) portability of reading skills; (3) reading rates and accuracy; (4) visual fatigue; and (5) interpretation of assessment results. (Author/DB)

This article describes the physiological mechanisms involved in three-dimensional depth perception and presents a variety of distance and depth cues and strategies for detecting and estimating curbs and steps for individuals with impaired vision. (Author/DB)

Provides practical advice for the teacher on helping the visually impaired child succeed in the regular classroom. Includes consideration of classroom and materials, adaptations, special subjects, such as physical education, and interpersonal issues. (SJL)

Identifies some functional vision problems and describes some assessment procedures for determining whether a child needs professional help. (MKM)

This article presents a practical guide to help professionals develop techniques and materials that motivate preschool-age children to learn to use low vision devices. Skills for optical-device training and sample training activities for monocular and magnifier use are outlined. (Author/DB)

A visually impaired rehabilitation teacher describes a model developed in Maine for providing low vision services, with emphasis on teaching the use of near-point aids to assist on near-point tasks. The article addresses preevaluation services, assessment of clients with low vision, and follow-up when the client begins using the aids at home. (DB)

Relationships between infant visual skills and the development of object permanence and expressive language skills were examined with 31 infants in three groups: visually typical, visually atypical, and Down Syndrome. Measures used to evaluate visual status were: forced preferential looking, optokinetic nystagmus, and behavioral. Object permanence…

Three experiments examined the ability of blind individuals and individuals simulating the visual acuity of 20/400 to monitor the behaviors of a cane traveler in various environments and at distances between 10 feet and 25 feet. Results suggested that at least some vision is needed for instructors monitoring visually impaired individuals learning…

To develop a battery of tasks to predict and improve mobility performance, a series of functional vision tasks (texural shearing, degraded images, embedded figures, and parafoveal attention) were generated by a microcomputer. Sixty visually impaired subjects given either computerized task training or real-life training improved their low vision…

The article describes a sequential training curriculum in the use of telescopic visual aids. The curriculum covers 29 topics, including aid maintenance, holding aid properly, focusing, scanning, target location, tracking, aid use for city bus travel, in a shopping center, and in a fast food type restaurant.

This article reviews some of the existing technology that assists children with low vision in their ability to use environmental cues. It provides recommendations for modification of color and contrast, illumination, space, and time. A chart lists technological assists for environmental cues and vendor information. (Contains references.) (CR)

A comprehensive program of instruction in the use of low vision is proposed, including definitions, a philosophy of low vision, theoretical constructs, a flow chart of professional and individual relationships and responsibilities, goals, curriculum, and an evaluation system. (Author/JDD)

A series of classroom experiences designed to experiment with the visual sense is described. Information is presented on materials and directions for activities exploring such aspects as stereo vision and dissection of animal eyes. (CL)
