Are his eyes normal?

[Ria P]

Someone just asked me what's wrong with my new foster hamster's eye.

The "white" that's not white of his eyes can be seen in both eyes in the corner.

I hadn't noticed this as abnormal when i checked him over and thought that some hamsters have eyes like that but now i'm not sure of course.

Does anybody know?

I thought i'd ask before i book a vet appointment because his eyes are clear and he appears to be able to see alright.
