Staying up late to work often leads to eye fatigue and disturbed circadian rhythms due to prolonged exposure to harsh screen light.
wps office下载 Office’s Night Mode is a thoughtful feature designed to reduce eye fatigue and improve comfort during extended work sessions under low-light conditions.
A darker theme lowers the visual contrast between display and surroundings, reducing eye tension and cutting down on blue wavelengths that suppress sleep-inducing melatonin.

To activate Night Mode, launch any file—be it a document, table, or slideshow—and navigate to the View section in the upper toolbar.
Click on Night Mode, and the interface will instantly shift to a deep gray or black background with light-colored text and icons.
This dark theme is uniformly applied to every part of the app—ribbon, navigation panel, and toolbars—so your workflow stays seamless whether you're drafting text, crunching numbers, or building presentations.
