The Benefits of Two Eyes

About two eyes

Our eyes allow us to see the world around us. We can also use this ability to judge the depth of things. We can do this by looking at objects from two different perspectives.

Binocular vision allows you to view the world in 3D, rather than just 2D, and this is one of its main benefits.

It gives you a way to determine the distance between you and an object, which is especially useful when there are obstacles in your field of vision. For example, if you have an obstacle behind you and are trying to see if it is a person, you will be able to tell from the distance how close or far away they are.

The third benefit of binocular vision is that it allows the angles of the lines of sight, relative to each other (vergence) and those lines relative to a particular object (gaze angle) to be determined from the images in the two eyes. This means that the eyes can see the entire scene and make a more complete judgment of what is around you, even when there is an obstruction in your field of vision.

However, if you suffer from strabismus, a condition in which the eyes are not aligned correctly, then this is a major barrier to your binocular vision. If left untreated, strabismus can lead to a condition called amblyopia.
