The world contains a model of the human eye, describing various parts of the human eye as well as their functions and how they work.

====Instructions====
“Take an
Instructon Book
Before (sic) you leave"
"Fly around
for the best
experience"
====Outside Eye Model====
"Cornea
The layer of
glass represents
the cornea" (sic)
"It focuses the
light coming into
the eye."
"It is filled with
liquid to maintain
its shape."
"Light that enters
the eye is
inverted by the
lens. Check"
"the inside of the
eye to see what
happens to it."
"Optic Nerve
This nerve
carries the
information"
"gathered in the
eye to the
brain where it is
processed"
"into an image.
This channel also
carries blood to
and from the eye."
"Enter the eye's
Vitreous Chamber
It is where vision
gets made" (sic)
====Inside Anterior Chamber====
"Enter the
Anterior Chamber
here"
"Anterior Chamber
This whole space
is filled with liquid
unlike in this"
"example."
"Aqueous Humor
This is a liquid
that fills the
entire chamber"
"is (sic) filled with
liquid to maintain
the shape of the
eye"
"Iris
The iris is a
muscle that can contract"
"to let more or
less light
through the lens"
"Pupil
The opening in
the Iris that lets
light to the lens"
====Inside Vitreous Chamber====
"This line shows
the light entering
the eye"
"focused by the
cornea,
restricted by the
iris"
"passing through
the Pupil, into the
Lense (sic) where it
is focused into"
"this room, which
is where it is
turned into
sensory data"
"The walls of this
room are called
the Retina, it
creates"
"peripheral vision."
"The spot at the
end of this line
is called the
Macula"
"which is where
your clear vision
comes from."
"In reality this
whole room would
be full of liquid:
Vitreous humor"
"Macula
This is a small
extra sensitive
area of your"
Retina that gives
you the focused
spot at the
center of your"
"vision. The light
from the lens is
focused on this
spot."
"Fovea
The spot of
clearest vision at
Macula's (sic) center"
"The Retina gives
your peripheral
vision. The Macula
gives you"
"centeral vision.
And the Fovea
gives you that
sharp point of"
"focus at the
very center of
your vision."
"If you wonder
why your vision 
is clearest in the 
middle, then"
"becomes more blurry as it
moves away from
the center"
"the Macula is the
reason."
"Optic Nerve
this nerve, which
carries
information to the"
"brain (sic) connects
to the retina
here. This spot
does not pick up"
"light, creating a small blind spot
in your vision."
"Vitreous humor
The entire eye
is filled with this
clear liquid"
"it (sic) maintains
the shape of the
eye, and
transmits light" (sic)
"If your vision is
cloudy, it may be
because this
liquid is cloudy"
"Suspensory
Ligament
Zonules"
"these attach
the lense (sic) to the
muscles that
manipulate it"
"bending the lens
and allowing it to
change focus"
"Ciliary Body
Muscles that
manipulate the
lens."
"Lens
This allows and
focuses light into
the eye"
"It flexes
and changes shape
to change focus."
"When light enters
the lens, it
inverts, as
represented with"
"this ray and the
opposite one
outside. Because
of this the"
"image your eye
picks up is
flipped and
backwards. Your"
"brain corrects
for this. And can
keep correcting
throughout your"
"life, making sure
up is always
perceived as up.
If you are"
"upside down long
enough, your
brain will actually
flip your view of"
"the world so it
looks right side
up again."
"Exit to outside"
