There is a lot you may not know about your eyes, which you are used to seeing the world with.
In this report, published by the Turkish newspaper Milliyet, ophthalmologist Dr. Serkan Goresar reviews amazing facts about eyes, some of which you may hear for the first time.
All children are born color blind
Gurisar shows that children's color perception is determined by several different tests.
At about the age of one month, the infant can perceive the brightness and intensity of colors, and by the age of 3 months he can see many basic colors including red, and at about the fourth month he develops full color vision.
A newborn baby does not shed tears when crying
Because the production of tears from the lacrimal gland located in the upper outer part of the eye begins in the first month, and reaches its full production capacity in the third month.
Newborn babies can clearly see objects at a distance of about 20-40 centimeters
The child senses the light while in the womb of his mother.
At birth, the newborn can distinguish between light and dark, eye contact begins at the age of 3 months, visual coordination develops, and he is generally able to track a moving object with his eyes, while the eye muscles are fully developed in the sixth month.
Contact lenses do not disappear behind the eye
Contrary to the new myth, contact lenses cannot get lost behind your eyes due to the structure of your eyeball.
The upper and lower parts of the eye are covered by a transparent structure called the "conjunctiva" through which no body can pass.
The lens may slide under the upper eyelid, and you can check this by turning the eyelid in reverse.
If the lens is not in your eye, we recommend that you look for it on the floor or on your table.
We see everything upside down
Dr. Gurisar refers to the fact that we see everything upside down, and that the main organ that restores the image to its correct form is the brain, where the light passes through the pupil and reaches the lens and refracts in it again, then passes through the vitreous fluid and falls on the vision area in the retina, and here is formed inverted image.
The inverted image formed in the brain is perceived at the area of vision and is transmitted by the brain and nerves to the visual center.
In the visual center of the brain, the inverted image is directly perceived, and this is how vision occurs.
If the human eye was a digital camera, it would have a resolution of 576 megapixels
Dr. Gurisar explains that the eye is the fastest muscle in the body.
So, when something happens quickly we say it happened "in the blink of an eye".
The human eye can operate 100% at any moment and without the need for rest.
If the human eye was a digital camera, its accuracy would be 576 megapixels.
This means that you need to put 576 million pixels into an area the size of your field of view to create a screen that displays an image so sharp that you cannot distinguish the individual pixels in it.
Our eyes collect the pieces around them, then send them to the brain to put the pieces together and create a complete picture, Gurisar adds.
And when it comes to our everyday visual experience, characterizing the eye by megapixels is pretty simple.

We blink more than 4 million times a year
According to Gurisar, the eyelashes blink an average of 4,200,000 times a year.
In general, the average person blinks 10 to 12 times per minute, and the interval between blinking in both eyes is between 2 and 10 seconds.
He confirms that the blinking of the eye is very important for the distribution of tears on the surface of the eye, knowing that the number of blinks is reduced by half during reading and using the computer.
