PDF viewer that can invert all colors (not only text)

Question

Because I am reading lots of pdfs from the screen, the white background make my eyes tired. Is there a decent lightweight pdf reader that can invert colors of everything on the page?

I have tried Adobe Reader and Foxit Reader but they only allow to change document colors, if a document is a scanned document everything stays the same.

Answer 1

This is the Windows version of Cory's answer. This assumes you use Windows 7.

• Launch the Magnifier. Search for it in the Start Menu.

• Click on the Gear icon to enter the options. In the Options, check "Turn on color inversion".

• Click OK to go back to the main window of the Magnifier.

• Click on the "Minus" button until it shows 100%. Then click on "Views" and select "Full screen".

Your complete screen will have the inverted colors. Including your PDF reader, you just have to put it full screen.

For Windows XP:

• Go to your "Start" menu and click on "Control Panel."

• Click the link called "Accessibility Options."

• Choose the task entitled "Adjust the contrast for text and colors on your screen."

• Check the option "Use High Contrast" at the top of the page under the "Display" tab.

• Open the "Settings" link to specify how you want your screen to look. Click "OK;" your current screen will close and you will be back on the "Display" tab.

• Allow the changes and keep your "Display" window open by clicking "Apply," which is helpful if you want to experiment with the contrasts. If you already know which setting you want and don't need the screen to remain open, click "OK." A small rectangle with the words "Please Wait" appears in the middle of your screen and then the inverted color scheme goes into effect.

Answer 2

Press Ctrl+Option+Command+8 to invert the colors of the whole screen.

Alternatively, you can go to System Preferences > Universal Access > Seeing > White on Black
