Well if you make the videos public and paste a link to them here we can watch them and see what we think.
There are so many possibilities as to why your new friend is biting, starting with his vision issue and from there it could be that he is hormonal or it could be related to something that previous humans did or he could just be mad because something is different enough that he is at a loss on how to deal with it or simply that he doesn't yet trust you enough. I would think that in most cases that it would take him longer to give his trust to you just because of his vision issue.
I really like to gather as much information as I can, although this is generally not possible before I say much. What was he being fed at the shelter that he is throwing out and was he actually eating it before?
