10 Amazing Facts About The Human Eyes

The eyes are a fascinating kind of camera that sees
things just the way they appear. Of course, what
could be more fascinating than a small ball-like
organ that captures a whole lot all at once and
then sends them to brain? They are not only
alluring cameras, the eyes are also one of the most
important organs that work every second of a
person’s life, one of the most powerful organs in
body that it uses about 65% of the brain as well as
one of the most easiest organs to manage. As a
matter of fact, people almost forget that they’ve
got eyes because it rarely gives them troubles
unlike other physical parts of the body except
those with eye problems. Still people know so little
about the eye, so we bring you some necessities
you really need to know about the eye. Glance
below to see some of them.

1. The Human Eyes Cannot Shed Tears Until 2-4
Months after Birth :
This of course explains why when a baby is born,
he or she never roll down tears even when they
cry out the loudest. This is because human eyes
cannot produce enough tears until after few
months of a human’s life and only produces
amount enough to lubricate and protect the eyes at
the time of a baby’s birth as the tear glands are
not yet fully developed until they are about 2-4
months old.

2. They Blink at Least 12 Times Every Minute :
Another fascinating thing about the eyes is that,
the eyes of an average person would blink at least
12 times within a minute. More amazingly, each
flutter movement of the eye would normally take
one-tenth of a second and thus humans really
spend more time with their eyes closed than they
know.

3. It Cannot Be Transplanted:
The eye is one organ of the body that is still
posing a big challenge to doctors in terms of
transplant. Doctors around the world have not
been find out a way to transplant. This is
burdened on a big reason that the optic nerves
which link the eyes to the brain are so delicate that
it is virtually impossible to reconstruct them
successfully.

4. The Eyes Have Blind Spots:
Did you know that of the human eyes have holes
on each of them known as blind spots? These
blind spots are as a result of a communication
between the retina and the optic nerve. But the
imparts of these blind spots in the eyes are faintly
noticed as the two eyes work together to pay for
the blind spot in the other.

5. The Eyes Can Be Differently Colored:
Some individuals do have differently colored eyes.
Some could be whiter, browner, and the host of
others darker. This is as a result of a condition
known as Heterochromia which can make a person
to be born with two differently colored eyes.

6. The Eyes Never Rest :
The eye works every second of a person’s life.
Even when you are taking a nap, your eyes never
really sleep. Other parts of it including eyelids and
exterior muscles of the eyes might take a break
sometimes but the major organ never really rest.

7. The Eyes Can Heal Very Quickly:
The eyes heal very rapidly and are among the
fastest healing organs in the body. Sometimes
tears may streak your eyes without you intending
to cry, or you may have dull ache, or even a red
spot on your eye on the edge of the colored part,
where it touches the white part, but before you
know it, it gets better on its own without you
meeting an ophthalmologist to get it checked out.
In fact, in 48 hours, a properly treated corneal
scratch would have healed completely.

8. The Eyes Have The Strongest Muscles:
The eye though fragile has the muscles deemed to
be the strongest in the body. Yes, the most
powerfully built muscles in the body are located in
the eyes. They move the eyes. The muscles of the
eye work constantly as they are always moving to
readjust the positions of the eye. For example in an
hour of reading a book the eyes make nearly
10,000 coordinated movements. So trash your
strong arms and legs as they are nothing to match
up with the muscles in the eye that are much
stronger.

9. About 39 Million People in The World are
Visually Impaired :
It is estimated by the World Health Organization
that about 39 million people around the world are
blind while more than 239 million people suffer
from one visual impairment or the other. Thus,
about 285 million people are estimated to be
visually impaired worldwide while 39 million are
blind and 246 are said to have low vision. But
about 80% of all visual impairment can be
prevented or cured according to WHO.

10. The Eyes are Very Fragile:
Despite the fact that the eye is the most important
organ in the body and takes care of about 85% of
the information any human would ever elicit, the
eyes are so fragile that the eyeballs weigh only
about 28 grams.
