What's wrong with my rabbit?

One of my rabbits (a 2-year-old female) is sitting in a strange way and behaving strangely. Her eyes are kind of weird, or rather her eyelids, but they're not closed. I have no idea how to explain it – you can see it in the photo. I just got her favorite treats and rustled them. She usually comes running over, but she didn't even move, and when I held them up to her nose, she didn't take anything. She's still grooming herself, but she's sitting in one place. What's wrong with my little one?

PS: she is neutered
