How do humans use their eyes to measure relative distance by parallax
A)By continuously focusing our eyes on distant objects, we can determine distance.
B)Since our eyes are separated, the brain interprets the relative look angles of these eyes in terms of distance to the object viewed.
C)Our eyes can measure the time it takes light to travel from an object and from this we get distance.
D)By moving our heads from side to side our brain compares look angles from each of these positions to obtain the distance to the object viewed.

Question

Quizplus · Accepted Answer

Our eyes are separated by a distance, and the brain interprets the difference in the visual angles of the objects seen by each eye in terms of distance to the object. This is called parallax, and it allows us to perceive depth and distance in our visual field. Options A, C, and D are incorrect as they do not accurately describe how humans use their eyes for measuring relative distance by parallax.
