Generally these adjustments are beneficial:
-Adjust the brightness of the display so it’s approximately the same as the brightness of your surroundings.
-Text size and contrast should feel comfortable. Black print on a white background is the best combination. According to computer vision expert, Dr. James Sheedy, the text should be three times larger than the smallest text you can read from your normal viewing position.
-Reduce the color temperature on your display. The term color temperature refers to the spectrum of visible light. Blue light (short wavelength) is associated with more eye strain while the longer wavelength hues, such as orange and red, are better for long-term viewing.
