This Australian study compared effects of relative-size magnification and relative-distance magnification on the reading rates of 24 adults with normal vision and 22 adults with low vision. For the subjects with low vision, the magnification method did not affect their reading rates, although subjects with normal vision showed slower reading at…

This paper presents a summary of presentations and discussion from a World Health Organization meeting of experienced low vision practitioners. It outlines the magnitude of the problem; current status of low vision care; enhancement of the use of vision; and recommendations in definitions, identification, assessment, low vision centers, education,…

The fourth in a series of Rand reports on information transfer problems of the partially sighted reviews earlier reports and describes an experimental secretarial closed circuit TV (CCTV) system which enables the partially sighted to type from a printed or handwritten manuscript. Discussed are experiments using a pseudocolor system to determine…

This article illustrates use of the alternating treatment design to assess effectiveness of individualized interventions in low vision rehabilitation. The design was used to determine whether enlarging copy (to one of two magnification levels) and adding contrast would be effective in reducing the time a visually impaired student required to read…

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.

This article reports on information provided by 109 teachers regarding the use of large type and optical devices, discussing teachers' confidence in instructing students to use optical devices, the criteria used to choose reading modes for individual children, and other issues. Cost factors and availability of large-type materials are also…

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)

Low vision students can be helped to gain an understanding of map reading and geography by means of products developed by the American Printing House for the Blind. Among those products are a series of eight land form models with accompanying audiotapes, a series of continental color coded relief maps, and 18 audiotapes for the six continents. The…

This report describes Project MAVIS (Materials Adaptations for Visually Impaired Students in the Social Studies), a three year project of the Social Science Education Consortium in Boulder, Colorado. The purpose of the project was to adapt social studies curriculum materials for use by visually handicapped students in grades K-6 in both integrated…

One of a series on the visual information transfer problems of the partially sighted, the report contains a detailed description of the double X-Y platform, a mechanical device used in conjunction with a closed circuit television system to permit users to read printed or handwritten materials and to take notes on or copy from the material. Also…

This article reviews literature on the issue of whether it is preferable to teach students literacy skills using large print or using standard print with optical devices. Findings indicate reading standard print with optical devices is as effective a literacy medium as large print and, perhaps, a more effective one. (Contains references.) (CR)
