Well, generally speaking, it is kind of annoying to have scratched eyes. And what is more, it can be very dangerous to have it too. For your situation, I will suggest you wear a pair of eye patches when you go to sleep. And in that way, it can be bothersome, but doing so it can protect your eyes well, and also, insure a speedy recovery for scratched corneas. In common, if your scratched eyes are not severe, it will take 24-48 hours for a basic scratch to heal. On the other hand, for some scratched eyes that include infections and it will also need oral and topical antibiotics and may take up to 4 weeks to heal. So you need to be more careful about it.
