Question

In human beings two eyes are positioned at the front of the head and it thus reduces the field of view in favour of what is called stereopsis.

• A. True
• B. False

Answer 1

The correct option is A

True

A human being has the horizontal field of view of about 150° with one eye and of about 180° with two eyes combined. The ability to detect faint objects is, of course, enhanced with two detectors instead of one and that we call stereopsis.

Some animals, usually prey animals, have their two eyes positioned on opposite sides of their head to give the widest possible field of view. But our two eyes are positioned on the front of our heads, and it thus reduces our field of view to enhance stereopsis.
