The human eye is one of the most complex and at the same time the most amazing organs of the body, which plays an important role in our understanding and experience of the world around us.. In addition to helping us see images and colors, this organ is connected to the brain to process visual information harmoniously.. href="https://gcorp.cc/">GCORP LLC Join us to introduce you to everything about the human eye.

Components of the human eye

This organ has different structures, each of which has an important role in the vision process:

• Cornea: is the main part of the eye that is located in the front of the eye and determines the color of the eye.
• Iris: It is the colored part of the eye where the pupil is in the center... This part adjusts the amount of light entering the eye by changing the size of the pupil.
• Lens: It is located behind the iris and refracts light like a lens.... In fact, the lens of the human eye helps to correctly form images on the retina.
• Retina:It is a thin layer of light-sensitive cells and is located in the innermost layers of the eye.... This part of the human eye creates an electrical signal after being stimulated by light.
• Optic nerve: It contains millions of nerve fibers that carry the electrical signal generated in the retina of the eye to the brain.... The brain processes these signals to become the images we see.
• Vitres: is a clear gel liquid that sits between the lens and the retina and helps maintain the shape of the eye.

How does the human eye work?

Before we explain how the human eye works, look at the image below to see what the human eye looks like under a microscope..

The function of the human eye is that the light first passes through the cornea and reaches the lens, and the lens focuses this light..

Light-sensitive rod and cone cells in the retina convert light into electrical signals. These signals are sent to the brain through the optic nerve. After processing the signals, the brain converts them into a correct and direct image to form the process of seeing.

How many megapixels is the power of the human eye?

Now that you are familiar with the components and functions of the human eye, we can answer the most common question about the human eye.... Most people are curious to know how many megapixels the human eye has.... To answer this question, it is good to know that the human eye is one of the most complex and amazing eyes of living creatures due to its ability to recognize and analyze images...

After a lot of experiments and research, scientists have come to the conclusion that the power of the human eye is 576 megapixels... Of course, you should know that megapixels are only one of the factors that determine the quality of the image and cannot be enough to describe the power of the human eye.

How many kilometers can the human eye see?

Another power of the human eye is that it can see objects at long distances. However, scientists believe that the exact amount of distance that the human eye can see depends on factors such as the size and brightness of the object, the clarity of the air, and the light conditions..

In studies conducted under ideal conditions, results were obtained that show that if a person is on the seashore, he can see up to four kilometers away... These studies have proven that the higher a person is above the surface of the earth, the more distance they can see.... For example, if you stand on a cliff with a height of 90 meters, you can see up to about 37 kilometers correctly.

Wonders of the human eye

Some of the wonders of this unique body part include the following:

1- Visibility

Our eyes have a viewing angle of 120 degrees horizontally and 90 degrees vertically.

2- Permanent movement

Our eyes are always moving, even when we sleep, the eyes don't stop moving... Eye movements are very fast to the point where their speed sometimes exceeds the heartbeat.

3- The ability to focus quickly

Another wonder of the human eye is its ability to quickly focus from a near object to a distant object... This ability is done with the help of the eye lens... The eye lens can change its shape so that the light is focused exactly on the retina.

4- Recognition of millions of colors

The human eye can recognize about 10 million colors.... This feature is due to the presence of three types of cone cells in the retina, each of which is sensitive to one of the three main colors red, green and blue.... The combination of different colors of these three main colors allows the human eye to see a wide range of colors.

5- shedding tears without crying

Another important and surprising feature of the human eye is that it can shed tears without crying.... Tears bring oxygen and nutrients to the upper layer of the eye and while preventing its dryness, they cause bacterial infections to disappear.

6- sensitivity to light

The human eye reacts to the smallest changes in light intensity... The pupil of the eye can automatically contract or expand based on the light intensity... This feature helps us see well in different light conditions.

7- Tears do not evaporate

In addition to water, tears contain fat and mucus.. For this reason, tears do not evaporate and if the eyes are not dry, we do not face a lack of tears.

8- Diagnosis of some diseases

Some signs and conditions in the eye can help diagnose the disease.... For example, people with uncontrolled diabetes may have a pale spot in the retina... Also, the retinal vessels of people with high blood pressure sometimes take the form of toothed and silver forks.... On the other hand, some experts use the size and speed of the eye to detect dementia and Parkinson's disease.>

9- 3D vision

Human eyes are positioned in such a way that each one records separate images.... these images are combined in the brain and form a three-dimensional image.... in this way, we can better understand the depth and distance of objects.

10- Automatic image correction

The image formed on the retina is upside down, but the brain automatically corrects it so that we see the image straight and correct.... This ability is one of the most brilliant features of the human eye and its coordinated function with the brain.

How many frames can the human eye make?

The human eye does not see frames per second (fps). Researchers have concluded that the human eye is capable of detecting changes in light up to about 60 Hz. This means that if light is turned on and off rapidly at frequencies above 60 Hz, it appears as a continuous light and the eye cannot detect its changes. The eyes can detect the difference between frames up to about 30 to 60 frames per second.

This amount can change among different people with different conditions.... It should be noted that sometimes the human eye can detect rates higher than 60 frames per second, but this increase in frame rate usually does not make much of a difference to the visual experience.

Human eye and its types

By closely observing the human eye, you will realize that this sensitive and important part of the body has differences in shape (almond, round and fluffy) and color (brown, blue, green and gray) in each person. Also, most people's eyes have differences in terms of visual function (camera, nearsightedness and astigmatism)... these differences are not only beautiful and the diversity of the face helps, but in some cases they require care and vision correction.

Comparison of the human eye with a photographic camera

The human eye and camera are both responsible for recording images, but the methods and features of each are very different.... To better understand the difference between the camera and the human eye, we have compared their features in the table below:

Comparison of human eye with eagle

The eyes of eagles are known as one of the best examples of vision in the animal world.... While the human eye has advanced capabilities such as color recognition and the ability to see in different lighting conditions, eagle eyes significantly surpass the human eye due to their unique features.... These features include seeing ultraviolet light, recognizing details at great distances and helping to be more successful in the field of vision, and hunting.

Guide to see a doctor

The structure of the human eye, in simple terms, is similar to a sphere, the cornea is located in the front part.... Undoubtedly, this important and sensitive part of the body can be considered one of the wonders of creation..

But, even the strongest human eye can be damaged under the influence of various environmental, genetic and biological factors.... If you notice the slightest abnormal signs in the eye, you should see an eye doctor.... For this, you can visit GCORP LLC and consult the best specialist doctor, including an online specialist... Also, GCORP LLC has made it possible for you to make an appointment with the specialist of your choice through the online appointment system to visit the eye doctor in person.
