The Irlen Colored Overlay Sample Pack includes one overlay of each color to help you choose the best color for you. Irlen 9″ x 12″ colored acetate overlays can be placed over printed materials to determine whether reading is made easier. Each sheet has a glare and non-glare side for increasing comfort. Each color is carefully determined by years of Irlen research. Not everyone is helped by the same color or combination of colors.
