Thanks for your suggestions! The developers currently have a long list of things to do, so I don't know if/when this content might be added. But we'll keep your ideas in mind!

In the meantime, you might be able to find some third party applications or invert the colors on your screen to reduce the amount of white light.

Let me know if you have any further questions!

I would love to see this option of a dark theme being added soon, thank you!

Let's just say that inverted mode on windows is nightmarish at best...

I second this!

Darkmode everything!!!11!!!

Yes! I agree! The screen is really bright!

Screen is really bright! And because i am a night owl it really hurts my eyes!

here's a link to the other feature request: https://khanacademy.zendesk.com/hc/en-us/community/posts/115008146288-SUGGESTION-Dark-Mode

Please bump this up! It's a critical feature for night/evening studies.

4 years and still no dark mode?
