The blind mole rat has a thin layer of skin covering its eyes, which is considered to be vestigial. There are also cavefish which have eyes that are vestigial. (There are also other vestigial traits in other animals that do not burrow.)

Vestigial means a very small remnant of something once larger. The appendix is a vestigial organ. Some people are born with vestigial tails.
They are vestigial structures, meaning they have no great significance to us today. If you believe in Evolution: Mammals had fur that raised when cold/frightened. Now our hairs do the same, but there's not enough to act like an animal's coat. You do have muscles attached to every hair, if you didn't know. If you believe in Creationism: We are special like that- God wanted us to have goosebumps. [Answer may vary.]
Vestigial structures are considered evidence, but no more critical than any other line of evidence in Biology and palaeontology. They're considered evidence, not because of their function, but because of the way their morphologies follow the nested hierarchies of biology: the vestigial legs of whales, for instance, have exactly the kind of shape we would have expected them to have if whales had descended from land mammals. The same goes for human tailbones and embryonic branchial ridges, the wings of emus, and so on.
