We do have some members here with blind bunnies and I hope they will chime in this weekend with some tips.
You can check out an older post that might be helpful https://binkybunny.com/FORUM/tabid/54/aft/110011/Default.aspx (but don’t respond to that post, it’s just for reference only)

My Vivian has recently gone blind in her left eye due to glaucoma. She can see out of her right, but it has a cataract so it’s not great vision. It took Vivian a couple of months to really become comfortable with it, as I could tell she just wasn’t understanding that she no longer had sight and so she would easily be confused when she could hear something from the left side that she could not see. She would not use her good eye to look around to check it out. But now finally she does do that more often. She is startled less now. But to make her comfortable, I just make sure to keep things in the same place. I also make sure I quietly say something as I come in. She hears my footsteps, but before, she would be startled when I would start speaking too close to her. So now I greet her more in advance. Then when I get close to pet her, I rub my fingers together twice – the sound mimics her tooth purr when I am petting her (she always does a gentle grind – two quick grinds moments apart — she and Jack used to also do this to communicate something when they were sitting a few feet from each other, but it seemed like they were doing this when they were relaxed, and it was as if they were just checking in with each other. I don’t know for sure what it means, just that it means something. Either way, when I try to mimic this sound with my fingers, Vivian is not startled when I put my hand on her head to pet her.

I had a bunny who developed cataracts and lost his sight. He may have had some sight left, but if he did, it wasn’t much. Like BB, I would speak to him as I was entering the room, and I made sure that the furniture, and his bowls and litter box were always in the same place, and not to set down anything new in his potential pathway. He would occasionally bump into the furniture, but for the most part, he got around pretty well. He was not caged, and he had a sweet companion to help him along and give him a lot of love.

No experience with blind bunnies. Only deaf. I do work with a blind bird though. He has a routine that we follow so he knows what is happening and when. His stuff is always in the same place. We also talk to him when we approach and give him verbal commands. I always try to announce myself when I’m close because he gets weirded out when he hears noises and he doesn’t know what’s going on. I would think it would be the same with a bunny. You would want to take care that you don’t startle them and you would want to make sure they know where everything is so they aren’t lost.
