21 Newly
Revealed Facts of Eye
Collaborated by : Ridho Iskandar
“The eyes are the windows of the world” as one well known
saying goes. However, there’s just more to the eyes than, well, meets the eye.
They allow us to see, first and foremost, as well as allow us to distinguish
shapes and sizes at first glance (literally). They also help us recognize our
friends and our loved ones. We
don’t often give our eyes as much thought as we should, that is until something
goes wrong and our vision is affected. But when you learn more about eyes, you
realize just how amazing they are. What your eyes do isn’t just limited to
these though; so here are 21 newly revealed facts about your eyes.
1.
Amount
of the eyes blink
Amount
of the eyes blink on an average of 17 times per minute, 14,280 times per day
and 5.2 million times a year. Fun fact: you blink more when
you’re talking than while you’re reading, We’re not sure about singing though.
Blinking helps remove any debris on your eye’s surface by
spreading tears over them. The tears help moisten and lubricate the eyes and
they also have important anti-bacterial properties.
2. People say “in the blink of an eye” because it’s the
fastest muscle in the body.
A blink usually lasts 100 to 150 milliseconds and it’s possible to blink
five times in a second. Well, just try it yourself.
3.
The
eye’s lens is quicker than any camera’s
Right behind the pupil is the lens, which focuses on objects you
look at. Take a moment to look around a room and think about the various
distances you’re focusing at. Each time, you do this, your eye’s lens instantly
changes focus without you even being aware of it. Compare that with a camera’s
lens which takes a few seconds to focus between this distance to the next. For
your information, the pixel of the eye is reached 576 megapixels.
4.
Everybody
gets cataracts as they get older
You
could think of cataracts as having similarities to getting gray hair in that
it’s just a normal, natural change as you age. The average age people first get
cataracts is around 70 years old.
5.
Your
eyes water when they’re dry
Tears are made up of three different components, namely fat,
mucus and, of course, water. If these three components aren’t exactly in their
right quantities, your eyes could become dry. Your brain responds to such
dryness by producing more of them!
6.
Eyes
heal quickly
With the proper care, it will only take around 48 hours for
the eye to repair a corneal scratch. And also 80% of vision problems worldwide are avoidable or even curable.
7.
Newborns
don’t produce tears
In spite of their crying sounds; babies tears don’t begin to flow
until they’re around 4 to 13 weeks old.
8.
Doctors
have yet to find a way to do eyeball transplants
The optic nerve, which connects the eyes to the brain, is too
sensitive to successfully reconstruct. An
eye cannot be transplanted. More than 1 million nerve fibers connect each eye
to the brain and currently we’re not able to reconstruct those connections.
Beside that, The Eyes are the second most complex organ after the brain.
9.
Heterochromia
This eye condition happens when a person is born with two
differently colored eyes. It named Heterochromia Iridis is a condition where each eye is a
different color. However there are plenty of famous faces in Hollywood branded
with this fascinating eye condition such as ; Kate Bosworth and Sarah McDaniel.
10.Eyes
began to develop 550 million years ago
The simplest eyes were patches of
photoreceptor protein in single-celled animals.
11.Your
eyes start to develop two weeks after you are conceived.
Before 2 weeks, the eye cannot
work, that’s why newborn babies cant see, they only can hear.
12.
The length of the eyelashes
The entire length of all the
eyelashes shed by a human in their life is over 98 feet or 29 meters with each
eye lash having a life span of about 5 months.
13. The Position of the Eye
To protect our eyes they are
positioned in a hollowed eye socket, while eyebrows prevent sweat dripping into
your eyes and eyelashes keep dirt out of your eyes. That’s why only 1/6 of the
human eyeball is exposed.
14. Size the Eyeballs is Fixed.
Your eyeballs stay the same
size from the age of 13 to death, while your nose and ears continue to grow.
15.The
Human Eye Weights
The human eye weights
approximately just under an ounce or 7.5 grams and is about an inch across or
24 mm.
16. Eyes can’t be Fooled but brains can.
When you look
at something, what you’re really seeing is the light that bounced off of it and
entered your eye, which converts the light into electrical impulses that your
brain can turn into an image you can use. The process that takes about a
tenth of a second but your eyes receive a constant stream of light, an
incredible amount of information, so it’s really difficult for your brain to
try to focus on everything at once. So your brain takes shortcuts, simplifying
what you see to help you concentrate on what’s important, which helps
compensate for your brain’s tenth-of-a-second processing lag. This trait helped
early humans survive encounters with fast predators – or at the very least, avoid
running into obstacles like trees.
17. Blindness
There are about 39 million
people that are blind around the world. People who are blind can see their
dreams if they weren’t born blind. That fact means from the total earth
residents which is 7.5 billion human, only 0.052 percent are blind.
18. Humans and dogs are similar
Humans and dogs are the only
species known to seek visual cues from another individual’s eyes, and dogs only
do this when interacting with humans.
19. The Retinaprint securer than Fingerprint
A fingerprint has 40 unique
characteristics, but an iris has 256, a reason retina scans are increasingly
being used for security purposes.
20. Red Eye
“Red eye” occurs in photos
because light from the flash bounces off the back of the eye. The choroid is
located behind the retina and is rich in blood vessels, which make it appear
red on film or image.
21.
What We See is What We Get
80% of what
we learn is through our eyes. That’s why 80% of our memories are determined by
what we see. You learn or study better when correlates with an image or video.
Speaking of video, we all know the power of youtube nowadays. Recent statistics
showed by fortunelords.com, Youtube has reached 300 hours of video are uploaded to YouTube every minute!, Almost
5 billion videos are watched on Youtube every single day, and YouTube gets over
30 million visitors per day.
The
Summary
Beside the complexities of the
eye, we can find many amazing and fun facts. From the explanation above, we
know ; The eye is consisted of millions nerve that makes it impossible to
transplant, Its length 24mm, its weight 7.5 grams, The fast-blinking eyes is to protect our eyes from the danger
also the eyeball is only 1/6 to be exposed as well, the RED EYE phenomenon came
from our blood vessels, You learn or
study better when correlates with an image or video.
