The Irlen Method helps eliminate a perceptual dysfunction (Scotopic Sensitivity Syndrome) through the use of transparent colored acetate sheets placed over reading materials to boost reading fluency,comprehension, comfort, and focus, as well as reduce light sensitivity.Encourage students to try different colored sheets or combinations of colors as they read to enhance print clarity and stability, reduce strain and fatigue, and improve concentration. Each sheet has a glare and non-glare side for additional options.
