Your favorite reading guides, now DOUBLE WIDE! If you aren’t familiar with reading guides, they are essentially tinted “window” strips that you can place over text. It’s like having a mobile highlighter that follows you along while you read and doesn’t mark up the pages. Above and below the window, there is also a section of opaque material to block the other lines. Reading guides can ease reading problems such as skipping lines, re-reading lines, eye strain & headaches, concentration, comprehension, and transposing letters. Measures 7” long x 1 ½” wide. The windowed area of these guides measures about ¾” wide, so it works well with larger print books or when highlighting a couple standard print lines.
