Check out the Preference Settings of your PDF reader. Find out the "Invert Colours" option and activate it. Most PDFs are plain text. So, this changes the black-on-white to a more comfortable white-on-black text. After that, lower the screen brightness to a level at which you feel comfortable.


Open a PDF file (any file) in Adobe Reader. Go to Edit>Preferences. In the Preferences window, click the ‘Accessibility’ tab and enable the ‘Replace Document Colors’ option.

Next, select ‘Use High-Contrast Colors’ and select a color scheme from the presets available. If you don’t need a high contrast color scheme but would like to make the document easier to read in low light/at night, select ‘Custom Color’ instead. You can then choose the color of the page, and the document text, and duly invert it so that the page color is black, and the text is white.
