Hi everyone, I was wondering if the greyish ring around my Syrians hamster's eyes is normal? It is symmetrical, and he has had it since I brought him home. He is 2.5 months old, I have registered him with a vet, but the waiting time to see a vet is two weeks. The greyish ring is more visible when he is standing so I'm wondering if it's just his third eyelid or if I should be worried and bring him to an emergency vet hospital.
Here is the link to the pictures incase the images attached don't work.

Any help would be greatly appreciated, thanks!
