A person with monocular vision covers one eye while reading a book.

Definition

Noun: * Vision with only one eye: The ability to see using only one eye, resulting in a significant loss of depth perception (stereopsis). This can be a natural condition for some animals or a result of injury or disease in humans.

Usage

This term is used to describe a specific visual condition. It is most commonly found in medical, biological, and optical contexts. * It is used to discuss human visual impairments. * It is used to describe the normal visual system of certain animals (e.g., many birds, rabbits). * It contrasts directly with binocular vision.

Examples

• After the accident, he was left with monocular vision and had to adapt to judging distances.
• Hawks have monocular vision on the sides of their heads, giving them a wide field of view to spot prey.
• The patient's monocular vision meant they could not perceive the 3D effect in the movie.

Advanced Usage

• Monocular cues: These are depth perception cues that can be perceived with one eye, such as relative size, interposition, and linear perspective. A person with monocular vision relies heavily on these cues.
  • Artists use monocular cues like shading to create the illusion of depth on a flat canvas.

Variants and Related Words

• Monocular (Adjective): Pertaining to, involving, or used by one eye.
  • A monocular telescope is designed for use with one eye.
• Binocular vision (Noun): Vision using two eyes simultaneously, providing stereoscopic depth perception. This is the direct antonym.
• Amblyopia (Noun): Often called "lazy eye," a vision development disorder where one eye fails to achieve normal visual acuity, which can lead to effective monocular vision if untreated.

Synonyms

• One-eyed vision (less technical)
• Uniocular vision (a technical synonym used primarily in medical contexts)

Related Phrases/Concepts

• Depth perception: The visual ability to perceive the world in three dimensions. Monocular vision severely impairs this ability.
• Visual field: The total area that can be seen when the eye is fixated on a central point. Monocular vision typically offers a wider total field of view but lacks the overlapping central field of binocular vision.
• Stereopsis: The perception of depth produced by the reception in the brain of visual stimuli from both eyes in combination. This is absent in monocular vision.
