Those are definitely mites. I bought a bp a while back and when she came to me she was soaking in her water bowl and had mites after I treated her she still had some mites left in her eye that couldn't just fall off. So if you sort of roll back the skin a bit by the eye like you would if you checking under your finger nail for dirt it should help the mite get out of there. Just be very gentle and it should pop right out. Hope this is helpful!
