Yes: There are two ways to not have pupils with an otherwise intact eye. 1) an inherited condition termed aniridia which always has a lowering of vision although vision is still useful and 2} traumatic aniridia in which penetrating eye trauma rips out the iris with vision afterwards approximating pre injury if there is no other damage and a lowering of vision to some level from concurrent eye damage.

To get a better...: Look at the retina without the pupils constricting when exposed to the light, at least that how it was once explained to me.

Dilation makes the pupil larger and remain larger in light. This enables the eye doctor to look in the back/inside the eye through the large opening (dilated pupil) instead of a small opening. enables better and more complete exam.

Maybe: Pupil size changes with emotion in most people. Fear and excitement can both cause dilation though, so you may not know which it is!

Eye doctor can check: An ophthalmologist (an md eye doctor) can check the eyes to see if the iris is behaving oddly, either dilating-contracting-dilating-contracting without changes in the surrounding light; or pulsating as if the pupil were moving in sync with the person's heartbeat. The doctor can do a thorough eye exam to make sure there is not a problem in the eye, around the eye, or behind the eyeball.

Depends: The pupil is the opening surrounded by the iris. The absence of a pupil either means something is in the way like a corneal opacity or that the iris is missing (look up aniridia). Those without iris can see although sometimes at a diminished level. The pupil could also be missing if the iris is constricted to a pin point or scarred down in which case vision would be bad or absent.
