All mammals have eyes. Even in mammals that are essentially 'blind,' the eyes are simply poorly-functioning but still existent. Some animals, namely cave-dwelling salamanders, to the best of my knowledge, have in fact lost their eyes. However, I believe a vestigial (non-working but not entirely disappeared) eye-like organ still survives that may not work at all, but may still be photo-sensitive(light-sensitive).

Why do cave dwelling animals have sightless eyes?
Cave dwelling animals may have sightless eyes due to a lack of light in their environment. Without light, there is no need for functional eyes, so evolution gradually led to the reduction or loss of eyes in these species. This adaptation helps these animals conserve energy and resources that would otherwise be used to maintain vision.
