I want black theme because my eye hurts from white bright

Questions & Answers
1

Godot game-engine has black theme, Android SDK has black theme, Visual Studio has black theme. Why aren’t you doing the same for Unity?

Staring at bright screen will hurt my eyes. If I have to use my common sense, I have to stop using Unity before I can even try and make a game, just because I’ve no access to dark theme.

If you speak of the editor, it does have a dark theme, just go to Preferences/Editor Skin → Pro.

If you speak of MonoDevelop, it does have it to, found under Preferences/Text Editor/Syntax Highlighting.
Hope this helps.
