Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If you had sight in only one eye, which of the following depth cues could you NOT use?
A
Interposition
B
Convergence
C
Shadow and Light
D
Linear Perspective
Explanation: 

Detailed explanation-1: -The closer the object, the more convergence needed. A person who lost sight in one eye would only be able to see monocular cues. They would not be able to view objects in 3D or stereopsis.

Detailed explanation-2: -Humans can perceive depth when viewing with one eye, and even when viewing a two-dimensional picture of a three-dimensional scene. However, viewing a real scene with both eyes produces a more compelling three-dimensional experience of immersive space and tangible solid objects.

Detailed explanation-3: -Depth perception works by your two eyes viewing different images and your brain bringing them together to form one single image. This process is referred to as convergence. This explains why those with vision in only one eye do not have great depth perception.

Detailed explanation-4: -Stereo depth cues or binocular depth cues are when the photoreceptors or movements of both eyes are required for depth perception. Our ability to perceive spatial relationships in three dimensions is known as depth perception.

Detailed explanation-5: -Monocular depth cue: A depth cue that is available even when the world is viewed with one eye alone. Occlusion: A cue to relative depth order in which, for example, one object partially obstructs the view of another object.
