as individuals to the world how does it
also affect our surroundings vision is
one of the five senses or abilities that
our human house some people believe that
vision is actually the most crucial or
important sense that we have as it aids
all the four other senses that we have
in different ways - so what is sight
that is the ability to see the things
around us with our eyes we all have
different eyes from colors to shapes
therefore we all see different
someone may seem to have extremely clear
vision and they're able to see 20 feet
away without a problem that means they
have 20/20 vision that person can have
almost perfect vision and say like that
pretty much in their entire life
people with not-so-good vision would
need glasses or contacts the actual
purpose of these sight magnifiers are to
aid your sight so that your eyes get
better adjusted to seeing more clearly
if your sense of sight is a bit foggy or
blurry at times
here are some special vocabulary terms
that you may or may not be already
familiar with vision the ability that
most people have to see things around us
site one of the most important senses
that we as humans have I a pair of
spherical organs located in the head
that serve a primary purpose of helping
us and being able to perceive different
objects or things around us peripheral
vision the ability to see to the side
while looking straight ahead anatomy the
study of the structure or internal
workings of something optical relating
to or having to do with the sense of
sight sight also helps us take everyday
important actions in life here are a
couple of examples of sight being in use
cooks and chefs must be able to see the
food they cook serve and eat so that
their customers are happy with the food
that they order people such as artists
must be able to see their writing
materials like a pencil and paper in
order to do their job gymnasts and
dancers need to know where they must

these things and last but obviously not

operations
the growing and shrinking of pupils also
known as dilation is you know that your
pupils can actually shrink and expand
based on what they are trying to see or
do in this clip we can see how their
pupils are shrinking from the sight of
extremely bright light in the flash
we couldn't get footage of someone's
eyes growing larger because when you
were in the dark your eyes try to adjust
to the lack of color but when you are in
the dark the darkness of the area forces
your eyes to try to be able to see the
more your eyes can't see the larger your
pupils get in order to try to adjust to
the lack of light since you cannot see
in the dark unless you have superpowers
this will lead your pupils to dilate or
expand
in conclusion we should not take our
sight for granted people who do not get
to experience sight blind people cannot
live the way that we do today
nevertheless their lives are in no way
worse or additionally unenjoyable than
ours thanks for watching and don't
