Abstract

This study investigates the change in reading comprehension ability of a child who has a distinct type of visual dysfunction, scotopic sensitivity syndrome when treated with spectrally modified lenses, Irlen filters. Recent research has indicated scotopic sensitivity syndrome as a major factor in reading disabilities. A single-subject A-B research design was used in this study. The Test of Reading Comprehension: Method for Assessing the Understanding of Written Language TORC (Brown, Hammill, and Widerholt, 1978) was used to measure the students reading comprehension. A visual analysis of the data was made by comparing scaled Conceptual/language ability and scores, comparing the General Reading Comprehension Ability. No change in reading comprehension ability was established when the student in the study wore the Irlen filters.
