Question

In human beings the total visual field and the stereoscopic visual field respectively is

• A. ${180}^0$and ${140}^0$
• B. ${140}^0$ and ${26}^0$
• C. ${180}^0$ and ${26}^0$
• D. ${140}^0$and ${52}^0$

Answer 1

The correct option is A ${180}^0$and ${140}^0$

The total visual field refers to the total area in which objects can be seen in the side (peripheral) vision, while you focus your eyes on a central point. It could be defined as that portion of space in which objects are visible at the same moment during steady fixation of gaze in one direction. In humans it is 180 degrees.
Humans and many other animals have stereoscopic vision, in which they see an object with two eyes at the same time, with both eyes set in the same plane. In human it is 140 degrees.

So, the correct answer is '180degree and 140degree'.
