Overlays are an inexpensive way of using colour. Placing the correct colour of overlay onto text reduces visual distortions such as movement of letters, squashed up text and wiggly patterns allowing the user to read more quickly and for longer. The colour of the overlay that works best is entirely subjective and down to the individual and his or her set of symptoms.
Professional assessment is required to ensure the optimum colour is prescribed to suit the symptoms of the user.
When you are reading, simply place the sheet over the page. The text beneath will still be well defined and easy to read through the colour.
Children can use coloured paper to write on, and photocopy worksheets, homework and music scores onto coloured paper of their choosing. The background colour of a computer screen can be changed from white to a more suitable shade similar to the overlay colour by accessing the control panel in the start menu.
