I'm legally blind, but I have enough vision to play Elite: Dangerous for the most part. The biggest areas where I have trouble are combat and docking. Combat can be avoided if I'm careful, but docking is a major pain for me. I wish there was a "Dock Assist that made the docking process more forgiving without docking automatically. This would also help players who are simly new to the game and haven't gotten used to docking yet. As for toggling it on or off, it could be done on PS4 for example by holding Triangle and clicking L3.
