In the latest discussion elsewhere about night racing, we forgot to mention this old trick: close your eyes for a few minutes, then increase the screen brightness and race. Stargazers will be able to explain why it works.
Now, when playing day races AT night, I recommend reducing the brightness, and on iOS: enable "Reduce white point" and, perhaps, "Night shift". You can adjust the level of both, and for the former it is possible to make it available in the home button triple-press.
Back to night races, enabling 'invert colors' might be an useful option!
