The most important cue to stereopsis (especially for fine stereopsis) is horizontal binocular disparity, which is utilized by visual system in a distributed and hierarchical fashion to retrieve a 3D layout of the external world.

The brain combines the clear images from the left eye and right eye. It processes these two images as a single, three-dimensional image. This is called stereopsis. Stereopsis requires that both eyes see clearly.
