Question

The vision of man is
A. Monocular
B. Binocular
C) Opposition
D) None of the above

Answer 1

Hint: Vision refers to the ability of man to see the beautiful world around him. It is one of the main sensory capabilities of man. Humans have two eyes and each of them form individual images. These images are combined and processed as a single image in the brain.

Complete answer: Vision is the sensory ability of an organism to see the surrounding environment. Vision provides one ability to search for food, to find suitable habitat, to predate, and to stay safe. Different organisms have different types of vision capabilities based on the structure of their eyes. The ability to see only from one eye is called monocular vision. Mono means single and ocular means eye. Both of the eyes form separate images that provide a wide view but less depth. Animals having eyes on both sides of their head have monocular vision. Binocular vision refers to the formation of two different images by both eyes which are seen as one. A three-dimensional image is formed in animals having two eyes facing the same direction. A wider field of view is formed as two images combine to form one. It is present in human vision. The vision of man is binocular due to the presence of two eyes that form two different images and then combine them.

Apposition vision is seen in insects majorly. They have compound eyes that make thousands of tiny images that are combined as one. A vast field of vision is created with more depth and detail.
So, option B is the right answer.

Note: Binocular vision shows some very interesting phenomena. Utricular discrimination is the ability to tell which eye has been stimulated by light. Eye dominance occurs when an organism uses one eye to aim at detail even if both eyes are open. Singleness of vision occurs when an object is seen as one through both eyes even though both eyes have their own image of the object.
