Many of us live on power point to make our points. Frequently, we might use a template that Microsoft or our company provides. Most of the time, the power point templates have a white or bright background with dark letters. All that white light on a screen (usually 30-60& of the screen doesn’t have text) can strain peoples eyes, and over time make them drowsy. This is especially true after lunch.
This is not the way to be eyes-friendly. Dark slides with white letters not only prevent eye strain, they conserve energy. It takes a fraction of juice to display a black background than a bright one.

PS: It looks very modern too, which makes it style friendly also.
