Why does my guinea pig squint her eyes?

They aren’t crusty or watery, and she squints both eyes to where they’re almost closed, but she squeaks and plays normal, is she ok??

Does she always squint or just when shes relaxing? Its normal for them to do it when relaxing but if they are always squinted I would be a little concerned. Has she gotten anything stuck in her eyes?
