This exploratory study investigated the effects of the components of visual environmental management, visual skills training, and visually dependent task training on the performance of visual behaviors of a young child with cortical visual impairment. These components were implemented by the mother during daily routines.

This article describes experiments designed to investigate reading speed and working distance for students with low vision. Six fourth grade students were asked to read unrelated words and continuous text ranging in print size. This article also discusses methods to maximize reading efficiency of students with low vision.

This article presents conceptual models of relationships between print size and reading speed and preferred viewing distances. These models illustrate how various factors can influence reading behaviors and influence decisions about the optimal angular size of print and resolution reserve.

The authors measured the light-distribution patterns and the decay in light output of three mobility lights that visually impaired persons can use for night travel: the Wide-Angle Mobility Light (WAML), the Streamlight, and the Mag-Lite. The WAML had a wide beam with a medium-bright central region. The beam of the Streamlight had the brightest central region and a moderately wide surround of lower illumination. The Mag-Lite had the narrowest light distribution about a bright central spot. Both the Streamlight and the Mag-Lite maintained near-maximum brightness before undergoing rapid decay, while the WAML showed a gradual decay changing from near-maximum brightness to near extinction in almost a linear fashion 40 to 80 minutes after being turned on.
