We understand the importance of an area in our body when that area temporarily or permanently loses its function. The simplest example of this is when we are sick, smell or we cannot taste We can show you. But we don’t have to wait until we’re sick to appreciate our unique features like these. How many of these features of ours, which seem very simple with a little research, exceptional You can understand that.

Now, although we have two eyes, which is one of our characteristics and remains a question mark for most people, we are in front of us. single image Let’s take a closer look at the situation. Let’s get to the point without further ado.

The answer lies in the relationship between our brain and our eyes.

First of all, we refer to a place or object. our eyes If we flip it, our brain processes that image and something like that, thanks to our different perceptions and the information we store. to see we do the action. When we have two eyes, our brain is dealing with two separate images.

Here ‘differentDon’t be fooled by our saying. Because our eyes are close almost Although they send exactly the same image to the brain, there are differences between these images because they are different in position. each other they are finishing We can think like

What happens to these two nearly identical images?

The relevant part of our brain processes the data received from our two eyes, which is much more sophisticated than either eye alone can provide. a single image we get.

So what exactly changes when this happens?

First of all, the fact that our two eyes create a common image allows us to obtain a three-dimensional image, which is immediately depth perception It means we win. This way you can measure the distance, width, length, etc. of something. we can understand it better. This situation, which occurs at the point where the images presented by the two eyes coincide, especially in the days when the ancestors had to hunt. Survive It was a huge benefit.

Another advantage of this display is that it offers a wide viewing angle.

Toppr

Normally we have one eye in the middle Our viewing angle is 95 degrees between our ear and the center, and 60 degrees between our nose and the center. In addition, from the center we have a viewing angle of 60 degrees upwards and 75 degrees downwards.

This means a viewing angle of 155 degrees horizontally and 135 degrees vertically. only one eye means come. In addition, each eye has a blind spot of about 15 degrees, originating from the macula, the central part of the retina.

As we normally say 155 degrees Our only eye gives us a vision. If it is at double eye level, this angle is more or less with the contribution of their position on our face. up to 190 interest.

Wouldn’t 155 degrees be enough?

Gift of curiosity

Close your right eye and hold your right hand with your left eye. you can see from the bring it to a point. If you open your eyes you can see how much difference this angle makes.

To see the difference in depth perception, from your friend you can ask for help. To understand this, close your eyes and ask your friend to place random objects on the table. Later only one eye Try to open it and reach for those objects. Since there is no depth sensing, your chance of missing with small differences will be quite high.

A few interesting facts:

  • Chameleons that can move their eyes independently with one eye It has a huge viewing angle of 180 horizontally and 90 vertically. Unique eye structures, between binocular and monocular vision patterns to make the switch and allows to obtain a panoramic image.
  • Although our brain presents the image as ‘single’, it causes us to see objects in pairs. diplopia There is a condition called
