Hmm, i dont know its Lottie, shes a German Lop REW, i have Ruby who is a Nethie REW, a fair gap in age, but Ruby has bright red eyes, where as Lottie, espec one eye, she has like a white glaze over it..
It just seems to of recently appeared :?
peice of hay perhaps?
i'm sure it's nothing to be worried about and getting her checked out at the vets will give you peace of mind.
it sounds like a cataract like my rabbit benji had and he had no problems with it.
hope you find out for deffo soon
