Reading-disabled children (n=92) were classified as either scotopic or nonscotopic using the Irlen Differential Perceptual Schedule. Use of either colored or clear overlays over reading material resulted in improved reading rate, accuracy, and comprehension when scotopic children read with the preferred colored overlay filter. Nonscotopic children…

The study examined the effectiveness of the use of nonoptical tinted (Irlen) lenses with 44 children (ages 9-16) with reading disabilities. Evaluation after 6 and 12 months indicated a significant improvement in attitude to school and to basic academic skills. Reading comprehension and accuracy, but not rate, were also significantly improved.…

This study of 36 backward readers (mean age=111 months) from the Netherlands determined that repeated reading-while-listening of the same text did not lead to better results (except in reading speed) than reading different texts, and asking readers to detect mismatches between written and spoken texts did not improve performance.
