Screen colour schemes and filters

• Look for the buttons on the front, side or back of your computer screen. 
• Switching modes changes the brightness and contrast of the screen, which can result in reduced discomfort and easier reading. 
• If you select the Custom option, you can adjust colour sliders to create a bigger effect. For example, see images.

Coloured overlays at World Wide Learning: select the coloured glasses to test which colour filter suits you best. Then you can place an order if you wish.

Coloured overlay clings at Irlen.com: a US site also sells coloured overlays which have an optical-grade clear adhesive to stick onto your screen. 

Before trying third-party screen display tools, it is worth checking out the different screen display options provided in Windows:

Night light

This is a very simple setting, but it might be all you need.  It gives an adjustable orange tint to the screen.

• In the search box next to the Windows Start button, type night light, then select the Night light app from the search results.
• Select the Turn on now button
  
• Move the Strength slider to increase the effect

When in dark mode, you can switch back to the white background by selecting the same button, which has changed to a sun icon.

It is very easy to change the background and text colour of pages in Microsoft Word. 

To change the page colour, 

1. go to the Design tab on the ribbon
2. choose a colour from within the Page Color drop-down. 

To change the text colour, 

1. go to the Home tab on the ribbon
2. right-click on the Normal style. 
3. Select Modify from the menu
4. select the Format button in the dialog that appears. 
5. In the new window you can change the font colour to affect the entire document. 

There are several different extensions that you can add to your Chrome browser in order to tint the screen colour.  Some of them dull the text and images, but an excellent choice is dyslex.ie. - which has additional, user-friendly tools for people with dyslexia.

1.  In Chrome go to the Dyslex.ie extension page
2. Select the Add to Chrome button towards the top right, then select the Add extension button when prompted
3. Select the Extensions icon near the top right of the Chrome window
4. In the displayed list of extensions, select the pin icon to the right of the Dyslex.ie extension.  (This places a Dyslex.ie icon on your address bar)
5. Close Chrome then restart it.
6. You should now see a Welcome to Dyslex.ie page.  (If not, open another web page that is NOT the Google search page.)  Select the Start button.
7. The first page is a questionnaire, but you can skip it.
8. You are then questioned about how dyslexia affects you.  You will be prompted to select your preferred font.  Finally you will be prompted to select your preferred screen colour.  The white background is now changed to your selected colour.
9. When you open a new web page, if the page colour does not change automatically, select the Dyslex.ie icon in the address bar.  (Unfortunately Chrome system pages remain white)
10. Each web page now has 3 round buttons in the upper right for settings, text only, and close
11. Select the settings cog button to display a menu where you can
• change text size
• change line height
• place boxes around paragraphs
• change the font  (one option is font Open Dsylexic)
• display a bright line focus bar
• change the colour tint and the background tint.  
• Note.  To give the screen display the best clarity, try leaving the colour tint switched off, but switch on the background tint
• The last menu option is to take the initial test again
