Signs of fur having been damp around eye

I have a 13 year old female chinchilla. I noticed the fur around her eye was a little darker than normal and looks like it may have been damp. I felt the area around her eye and it does not feel damp or wet.



I took some photos. One photo looks like she is squinting really bad but its just a photo that she is blinking from the flash. She is not squinting like this normally.



Does this look like enough of a concern to take a trip to the vet?
