Here are the steps to change background color and text color to something a little more eye-friendly in Adobe Reader: This will help you maximize screen readability while minimizing eyestrain. You can easily change both text and page color of a PDF document while reading without making permanent changes on the document itself. Luckily, Adobe Reader has such an option.

Our eyes have grown used to seeing this color combination in traditional print format, but this scheme is of limited suitability on a computer screen. Adobe Reader, by default, open PDF documents with black text on a white background (unless set by the PDF author).
