5 Strange Facts About The Human Eye, you never knew . . .


my name is Emma, and welcome to Esoteric Detective.
One thing that all of us are born with, usually anyway, is a pair of eyes. We all have them,
and use them regularly, to do things like look at this strange world we live in. And
to look at things like this video. But they are also shrouded in a kind of mystery.
Anyway, stay tuned, as Esoteric Detective brings you, five strange facts about the human
eye. And make sure you stay until the end, because the last fact . . . .will blow your
mind. . . . .Number 5. . . . Blue eyes. We have all seen them before, on
someone. Maybe a family member. Or maybe when we look in the mirror. But if you have blue
eyes, then you are only a member of what is a recent genetic mutation. For blue eyes were
part of a mutation that occurred only 6000 to 10,000 years ago. To put that in perspective,
brown eyes have been around since the beginning of humans, and that is about 200,000 years.
Hans Hiberg from the Department of Cellular and Molecular Medicine at the University of
Copenhagen, states that, “Originally, we all had brown eyes. But a genetic mutation affecting
the OCA2 gene in our chromosomes resulted in the creation of a ‘switch,’ which literally
‘turned off’ the ability to produce brown eyes.”
But in the end whatever eye colour you have, and whatever shape, we all sooner or later
cry, which brings us to number 4. Our tears. When you cry, your tears are not the same
as when you yawn or when something irritates your eye. They have a different composition.
In fact, different tears, that is, tears of joy or tears of sadness, even look different
from each other. In fact one woman named Rose Fisher proved this, by taking different pictures
of tears under a microscope. She studied 100 different tears and found
that the tears that come about from hard laughter aren’t even near to the tears of sorrow.
Like a drop of water each tiny tear drop carries a microcosm of human experience. Her project
is called The Topography of Tears. Each picture is taken from a different tear.
And they have a different structure. You can tell just by looking at them, the difference
between pain and laughter. It is quite amazing. . . . .Number 3 . . . . Your retinas don’t
see the world the way you think they do. In fact, you see the world, upside down. It is
your brain that flips the image right side up, so the world looks the way it should.
Which gives rise to the question, if the brain flips the image right side up, without us
even knowing it. Then what other ways does it fix the image that is coming through our
eyes. Well, it also un scrambles the image, because the image that comes to your eyes,
is split in half. Your brain puts two halves of the image back together. It also fixes
the problem that you cannot really see the colour red. That’s right, if it is your favourite
colour, it is a figment of your brain. Your retinas cannot detect the colour red at all.
It is your brain that blends the colour together in order to make it, because your retinas
cannot record it at all. Number 2 . . . . men and women, are not equal
. . . The eyes of women and men, at least how they
see the world, is much different. In fact, the brains of women and men, process colours
in different ways. New Research has shown, that if both sexes look at the colour orange,
for example, that men will see a redder version of orange than a woman will see. That is,
a woman will see a lighter version of orange. This is the same for many colours, but you
can take the colour green for example, a woman will see a much greener colour of green, where
as, a man will see a dark colour of green. Researcher Professor Israel Abramov, states
. . . that differences between the sexes’ colour vision cannot be explained by differences
in the structure of the eye. Therefore, the answer must lie in the way the brain processes
information taken in by the eye. Number 1 . . . . eyes are a doorway to the
soul . . . Recent research made by vision researcher
Giovanni Caputo from the University of Urbino in Italy…. has shown that staring into the
human eye, either your own eye in a mirror, or the eye of another person, changes the
consciousness of humans. Forget hard drugs, if you stare into your own eye it is much
cheaper and better for your health. A few years ago, researcher Giovanni Caputo recruited
50 volunteers and got them to look at their reflections in a mirror for 10 minutes in
a dimly lit room. For many of them, it took less than one minute to start experiencing
something very strange. Their faces began to warp and change, taking
on the appearance of animals, monsters or even deceased family members; a phenomenon
imaginatively named the “strange-face illusion.” But it seems the effects are even more strange
when the mirror is swapped for another person. According to the British Psychological Society,
those in the group that faced one, looking into the eyes of another person 3 feet away,
experienced higher levels of attenuated colour intensity, with noises also seeming louder
than they should. Time seemed to slow down and they felt their minds empty of all thoughts.
Additionally, almost all of them said their partner’s face appeared deformed, two thirds
saw monstrous beings and 15% even saw traits of a relative’s face emerge on their partner.
So I guess the eyes are really a window to the soul. Or maybe something else.
