In the current version of the game, it is not possible, but I believe the dev has said they're looking to change it in the future.
Oh... that's sad, but okay, I guess the poor visibility from the window adds to its ambiance lol :)
If you want a tip I found to be great, you can try turning off Color Correction in the settings. It removes a filter from the graphics that make things so much clearer. It won't be perfect, but it definitely looks better to me.
