The contents used in display are classified as video, graphics, characters. The contrast ratio is the most important factor in video because typically the full video screen was offered about 30 percent of brightness in white base.
The human eye has far superior ability to identify objects in the dark place than in the bright sport. And the human eye can identify the things within certain distance even in the dark places and could not get tired with a long time use in the dark places.
So a high contrast product is much better for the human eye.
