Question

Identify A and B components from the image about binocular vision.

• A. A -- Simultaneous perception and B -- Stereopsis
• B. A -- Simultaneous perception and B -- Fusion
• C. A -- Fusion and B -- Simultaneous perception
• D. A -- Stereopsis and B -- Fusion

Hint:

Binocular vision grades: Simultaneous perception $\rightarrow$ Fusion $\rightarrow$ Stereopsis.

Answer 1

The Correct Option is B

Concept: Binocular single vision has three grades: simultaneous perception, fusion, and stereopsis. Simultaneous perception means both eyes perceive images at the same time. Fusion means the brain combines two similar images into one.

Step 1: Understand simultaneous perception.
If the right eye and left eye see different images and the person perceives both, it represents simultaneous perception.

Step 2: Understand fusion.
When similar images from both eyes are combined into a single image, it is called fusion.

Step 3: Match A and B.
In the image-based question, A represents simultaneous perception and B represents fusion. Therefore, the correct answer is A -- Simultaneous perception and B -- Fusion.
