There is now scientific research to show that both coloured filters (worn as spectacles) and coloured plastic sheets laid over text (known as overlays) can help some children to read.Ĭoloured overlays are sheets of translucent or transparent coloured plastic that can be placed over a page of a book so as to colour the text beneath without interfering with its clarity.Ĭoloured overlays reduce the perceptual distortions of text that children sometimes describe. 5 best reasons colored overlays help overcome dyslexia symptoms.
