I am doing research for a story i am writing and i was wondering if you can see without pupils?

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.
