binocular vision
Definition
Noun: * The ability to perceive a single, three-dimensional image of one's surroundings by using both eyes simultaneously. This type of vision provides depth perception.
Usage
- "Binocular vision" is a technical term used in biology, medicine (especially ophthalmology and optometry), and zoology.
- It describes a specific visual capability, not the act of looking with two eyes. You binocular vision; you do not it.
- It is typically used in scientific, academic, or clinical contexts.
Examples
- Humans and many predators have binocular vision, which helps them judge distances accurately.
- The optometrist tested the child's binocular vision to ensure both eyes were working together properly.
- A lack of binocular vision can result in poor depth perception and may be a sign of strabismus (crossed eyes).
Advanced Usage
- Stereopsis: This is a more specific term for the primary component of binocular vision—the perception of depth and 3D structure based on the slight difference in the images from each eye (binocular disparity).
- Field of view in binocular vision: While providing depth perception, binocular vision often comes with a narrower total field of view compared to animals with eyes on the sides of their head.
Variants and Related Words
- Monocular Vision (n): Vision using only one eye, which lacks the depth perception provided by binocular vision.
- Binocular (adj): Involving, relating to, or designed for the use of both eyes (e.g., , ).
- Binoculars (n): An optical instrument with a separate lens for each eye, used for viewing distant objects. This is a common compound word derived from the concept.
