YouTube has a feature that allows viewing YouTube without glares at night. The Dark theme allows to tone down your computer screen’s glare. To enable the dark theme, first, select the Youtube settings (click the top three vertical dots), Click the first option ‘Dark theme:On’. A message appears, “Dark theme turns the light surfaces of the page dark, creating an experience ideal for night. Try it out! Your Dark theme setting will apply to this browser only.” Turn on the ‘Dark Theme’ slider.
In Android Phone, Select your profile picture. Tap Settings. Tap General. Tap Dark theme (Enable dark theme throughout the app), toggle the feature to turn on or off.
In the iPhone or iPad, Select your profile picture. Tap Settings. Tap Dark theme to toggle the feature on or off.
Bonus Tip
Do you have the habit of watching Youtube for a long time without taking a break? There is a solution to the Youtube app. Just above the dark theme setting, there is ‘remind me to take a break’, tap right it to set the reminder frequency.
