Binocular Vision Quiz

Binocular vision is the ability to perceive a single three-dimensional image of a scene with both eyes, giving us depth perception and the ability to judge distances.

When one eye is closed, the range of the visual field is reduced, and the individual loses the depth perception and binocular cues.

The refractive power of the eye inverts the images, but the chiasm and the crossing of nerve fibers ensure that we see a real image.

<p>The crossing of nerve fibers ensures that the nasal fibers obtain information from their respective lateral fields while the lateral fibers obtain information from the middle field, ultimately allowing the brain to interpret a complete visual field.</p> Signup and view all the answers

<p>Nerve fibers from the right temporal side go directly via the optic nerve to the lateral geniculate body, while the right nasal fibers cross over to form the left optic tract. The nasal fibers from the left eye cross and eventually reach the right side of the brain. The pathways then connect to the visual cortex located in the occipital lobe.</p> Signup and view all the answers
