Usually, the default background color of PDF files is white. When you are reading, all the white background looks very tedious inevitably. Maybe you also have a problem: If you read and edit the white and black documents for a long time, or you focus on a computer screen for too long, this can lead to dry eyes and eye fatigue.



Distance vision may help relax our eye muscles, which stops eye fatigue in its tracks. But we are inescapable to spend much time processing our documents with computer and telephone, so what can we do to solve the above problems?


PDF Reader Pro for Windows introduces the Theme function and provides different theme colors for you to choose from. There are four main themes: Light, Sepia, Dark, and Reseda.



- Light: This is the default background color. If you want to make your documents look more brightly, you can choose it.

- Sepia: It displays the document on a light–yellow background. When you feel the Light theme is too bright to handle your files, choosing the Sepia theme will make your background softer.

- Dark: The Dark theme displays the document in a dark environment, which maintains a minimum color contrast ratio required for readability. The Dark theme is so friendly for visually impaired people.

- Reseda: When you read your files for a long time, it displays the document in a light-green background to please your eyes.

- More themes as you like: If you feel boring when you always read the same background color in your documents, you can choose more colors as you want. You also can change the PDF font color at will in PDF Reader Pro for Windows!
