More generic, Can an n-dimensional being ever see an n-dimensional object?. It is my understanding that both of our eyes are capturing projections, and without both of them, we will lose our sense of depth perception. But is sensing depth enough to claim we can see 3D? If humans were 2D beings, then how could we see anything other than straight lines or line-segments? And if we were 4D beings, wouldn't it be only then we can sense 3D?

[EDIT]: Before posting this question in PSE, I read about image construction in the retina(s) of a human, so I need to clarify something. By using the word actually, I want to transcend our understanding of seeing beyond reconstruction of a 3D model and have a discussion about how beings in other dimensions are capable of seeing things and how that sense is quantitatively less/more than our (beings in 3D space) capabilities, thus creating a direct relation between the dimension we live in and the way we measure objects by looking at it. Thanks for all your replies.
