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 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…

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)

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)

The Department of Veterans Affairs VICTORS (Vision Impairment Center To Optimize Remaining Sight) Program emphasizes individual independence through the use of low vision devices and training. The social worker's role combines traditional counseling with administrative responsibilities, such as interviewing the patient to identify needs and…

A telephone survey of 147 participants, ages 27 to 96, in a low-vision service program of an urban vision rehabilitation agency found that most respondents continued to use their devices every day for months after low-vision services were completed, and three-fourths reported that the services had a positive impact on their everyday functioning.…

To investigate whether screen color is an important variable in the prescription of closed circuit television (CCTV) systems, 16 adults with low vision were assessed on reading performance on white, green, and amber screens. When the screen luminance and contrast were equated for each CCTV, subjects' reading performance was unaffected by screen…

One of a series on the visual information transfer problems of the partially sighted, the report describes an interactive, multicamera, multimonitor closed circuit television (CCTV) system that permits continuous visual communication between teacher and students in an elementary school resource room. The system (in use since November 1973) is the…

Intended for individuals losing their sight and for families of these individuals, this guide presents methods of performing basic tasks of daily living, addresses common feelings and fears, and offers suggestions for additional help. An introductory chapter outlines how to use the guide. Subsequent chapters address the following topics: (1)…
