I do not have any experience with blind animals, but I do think that if this is the only problem that the animal could thrive. I watched a show where someone covered a snake’s eyes to see if it would still eat without being able to see the prey. The snake ate normally. It did not need its eyes to find the prey.

If the snake can thrive in captivity, and you are willing to keep a blind animal, then I do not see any reason that you should not adopt this animal. Personally, I would not take in a special needs case, but I applaud you for it.
