One eye of my hamster has become very strange. Why is the corner of my eye a little white?

Is the middle of the eyeball white? The white in the middle of the eyeball is cataract. Hamster cataract is generally considered as a part of the aging process, and diabetes itself is easy to cause cataract. Such hamsters will lose sight or even be completely blind, but hamsters mainly rely on smell and hearing, so the impact is not too great.

I wonder if it's white next to it.
