The study examined whether individual levels of optimal illumination could be reliably determined for visually impaired adults and whether the level identified in the assessment had validity in relation to a practical reading task. The assessment procedure was found to be reliable and valid and reading performance improved. (Author/DB)

The study assessed variations in the indoor and outdoor locomotor mobility of 22 low-vision adults, under normal and reduced illumination. Subjects' visual fields and contrast sensitivities accounted for 39 percent of the variation in mobility performance, whereas their visual acuities were not related to mobility performance.

This open-ended survey of 156 subjects (78 pairs of visually handicapped orientation and mobility specialists and adult clients) identified common low vision mobility problems (lighting conditions, drop-offs, street crossings, changes in terrain) and found a high degree of agreement between the reported perceptions of mobility practitioners and…
