Do you know that the size of your eyeballs increase with time? If no, then a lot of interesting and amazing facts about human eyes are given here…
There are a lot of misconceptions and myths about human eyes. For example, you might have heard your parents saying that sitting too close to television could damage the vision. In addition, your elder brother or sister might have criticized you in the past for reading a book in dim light.
It is understandable that some parts of the eye are difficult to understand and that every eye has over one million optic nerve cells and more than 100 million photoreceptor cells that make it one of the most complex organs of the human body. However, there are so many interesting and shocking things about the human eyes that we all don’t know.
The Size Of Your Eyeballs Increases As You Age
It is a common misconception that the size of eyeballs remains the same from birth to adulthood. However, it has now been proved that eyeballs increase in size or grow larger with time.
As a newborn, the measurement of your eye will be three-fifths of one inch from front to back. However, when you grow up, the size becomes one inch.
Please remember that the size of eyeballs increases to an extent in the first three years of life. Another growth spurt occurs when a person reaches his or her puberty.
Jelly-Like Substance In Your Eyes
Can you tell me the name of the jelly-like substance in your eyes? The name of this substance is Vitreous. It is known to fill the space between the retina and the lens of the eyeball.
One of the best things is that this jelly-like substance (meaning the vitreous) is present in the eyes of humans and other vertebrates. You will be surprised to hear that this substance is 98% water and the other 1% has components that are important to maintain the shape of the vitreous.

What is the color of your eyes? Most people in the world have either brown eyes or black eyes. It was not until 8000 years ago that the first blue-eyed person was born as the result of genetic mutations.
It is widely believed that the mutation of the OCA2 gene has stopped producing brown eyes, which means it now produces blue eyes only.
