The surface features of an object as being farther away and larger retinal images are perceived as closer

How are smaller retinal images perceived in terms of distance in relative size?

Smaller retinal images are perceived as being further away.

How are larger retinal images perceived in terms of distance in relative size?

Larger retinal images are perceived as being closer.

What is height in the visual field?
