Coloured Overlays
Coloured overlays, (or dyslexia overlays as they are sometimes known) can increase reading speed, help comprehension, and reduce headaches and migraines
Difficulty with reading black on white, such as words appearing to move around on the page, or letters seeming to blur or fade, is called visual stress. This is common in dyslexia and other specific learning difficulties, but can exist on its own. Reading through the right colour can help reduce the visual stress that is often connected with dyslexia.
