A presentation of AIT.
When you Morning and look in the mirror you see your eyes,
mouth, teeth, hair, ears and nose, your muscles and bones give
you a real good place for you to wear your clothes.
You've got your. and brain and heart and what we
a Put together why we do what
we do. Like me and you look like you. It's
a bunch of neat stuff. It's fun.
So
Oh. Oh
hi, Naomi, come on in. Hi, Chow and Sarah are already here.
So what's new? What's different about me? What's different
about you? Uh
You have a new shirt. No, no,
uh, OK, uh, you have a new pair of shoes.
No, no. Well, there is something different about you, but I can't quite see what it is.
Um, I know you've got a new haircut.
Oh, you have new glasses. I didn't notice that. Hey, everybody, come here. Look,
Naomi's got some new pair. Isn't that neat? Can you see better now?
A lot better before I had trouble seeing things far away. Well, how did you know what
kind of glasses to get? I went to the eye doctor.
OK, Naomi, I'm gonna have you hold this and I want you to cover up your right eye for
me and you see that chart out there? I want you to tell me the smallest row of letters that you
can read. And take a guess. It's all
right to guess. L
H P. Oh
See, good job. OK, now I want you to cover your other eye and I want you to do the same thing.
Tell me the smallest row of letters that you can possibly read. OK, Naomi,
I'm gonna have you put these red green glasses on.
OK, can you see those dots out there? Yeah, OK, I'm gonna cover one
eye. Tell me what's the number of dots and what color they are.
3 and the green.
And what about now? 2
And they're ready. OK, now what we're going to have you do, I want you
to look out in the distance for me and just keep looking out there. Good. I'm gonna
be shining this light in your eyes. Just keep looking out there.
Good.
OK, now what we're gonna do is put some lenses in front of your eyes
and you go ahead and sit back and see if this these
lenses will improve your vision. What I'm gonna have you do
is look out at the chart. Can you see that row of lines? Yeah, all right, I
want you to tell me when that first gets a little bit blurry to you. It's a
little blurry. It's a little blurry. Can you make it out here?
No, no, OK, I want you to tell me when you can first see a letter on that line.
I can see a letter. OK, does this improve in any? OK,
what about here? Does it look the same?
Looks the same. Looks the same. Good. OK, I want you to keep looking
at that low of letters and I want you to tell me which one looks
better to you.
One Or 2
One good. OK, Naomi, what we're gonna
do now, if you look out through those lenses and then look
out without the lenses, which looks better. With the
lenses. OK, good. So what we're going to do now is go to the
frame room and help you pick up some glasses for your new prescription.
OK. The only hard part was
deciding which ones the best.
Hm.
Yeah.
I like these, and these are the ones I picked.
Well, they look great. Well, you know, since we're talking about glasses, this might be a
good time to think about how our eyes work. Do you guys know how your eyes work?
Well, let's go over here and have a look at what the eye looks like on the
inside. This Is a
model of the eye. Yeah, it is Sarah. It's
a lot bigger than your real eye, but that's just so that we can see what it looks like in all its different
parts. Looks kind of complicated, doesn't it? Hm, where should I start?
Uh, OK, I know one of the things that your eyes can do is
move. Can you move your eyes and your head? Can you move your eyes and your head back and
forth, side to side like that? Now it's a good thing that your eyes can move
because, well, can you imagine what it would be like if your eyes look straight ahead all
of the time? Like what do you think it would be like to read a book? I'll show you.
Yeah, that's right, left, right, left, right, left, it's right. Your neck
muscles would get pretty sore just reading a book, you know, you look like a cat when you do that.
The cats cannot move their eyes very much in their head, and if you play with a cat,
they have to follow. If you play with a string, you know, the cat goes they move their whole
head because they can't move their eyes like we can in our head, you know, something else,
because your eyes can move in your head, you can see when you walk down the street if
your eyes are just straight ahead, everything would be really blurry, be something like this.
You know what this is? A camera, right? It's a video camera. Now it's kind of like an
eye, isn't it? Sort of like an electric eye and this part at the front here,
the eye of the camera, cannot move in the camera like your eyes can move in your
head. So if you walk with a camera down the street and you're not
careful and you're just kind of going oh look at that.
Over there. Oh look at that down there. Look at this up here. The picture gets really
blurry, right, because it's moving too fast. It can't compensate, but when
you walk down the street, you can move your head and your eyes stay
pointed straight ahead. Can you do that? See if you can look straight ahead, move your head up
and down like that or side to side and keep your eyes straight ahead. See how your
eyes can. Keep looking, that's so that you can see when you
walk. Well, what do you think it is that makes your
eyes move like that in your head? muscles, right? Anything
that moves in your body moves by muscles, and that's what these red things are, these
long red things on the eye. Those are the muscles that make it move and those little
muscles work really hard because your eyes are moving all the time. Those
muscles move about 100,000 times a day. Isn't that
amazing? Never stop moving. Now there's another part of your eye.
Suppose you were sitting in a room by a window and all of a sudden this
really bright sunbeam comes flashing through at you. What would you do,
Naomi? I took the shade and what would that do? Keep the light
from coming in, right? Well, there's a part of your eye that does the same
thing as a window shade, and it's called the iris, and it's right at the front,
and that's the part of your eye that usually has color to it. And
in fact, hm, I can see 3 different colors of
iris right here. Charles Iris is kind of brown
and Sarah's iris is kind of blue, hazel, and
Naomi's iris is really dark brown. Uh, what color are mine?
Brownish brownish reddish brownish green.
Here's an iris. Watch what happens when the light gets brighter.
Did you see it closed down? And when the room gets darker, the
iris opens wide. Now that black spot
in the middle of your eye that gets big and small when light shines on it that has a
name and it's called the pupil. Pupil like in
school, yeah, it's got the same name as the pupils in school,
Sarah, but this one's a little different. Let's look at the pupil that's in the iris of
this eye. We'll take it apart here. First we'll take the muscles off
these red things. Remember the muscles that let your eye move in all those different ways,
and we'll take the eyeball off the top here and.
Right at the very front of the eye. There's the iris. That's the part that
has the color, and right in the middle you see that hole? That is the
pupil. Now I wonder what would it be like if light
could not go through that hole could not see anything. Yeah, that's
right. If there was no light going through the pupil, it'd be dark. You couldn't see anything at all. Now
after the light goes through that, then, um, Chow,
can I borrow your magnifying glass that you were using earlier? Sure.
Do you want to look at something with it? Yes, I do, Sarah. I want to look at something, but I
also want to look at a part of the magnifying glass itself. Have you ever seen one of
these? Do you know what the glass part of the magnifying glass
is actually called? Naomi, do you know the lens? Very good. It's the lens
just like the lens. In your glasses and lenses are neat because you can look at
things with them and sometimes things look kind of fuzzy but then when you bring
it down a bit it gets really clear and it becomes
focused. You can see a nice clear picture with the lens. Well, right at the front
of your eye is a lens look at this.
It's got exactly the same shape. It's curved and when
light goes through that, it can make focus pictures just like a magnifying glass
can. Now you can actually make a working model of your eye with stuff you can
find in your kitchen. Here's something you might try at home. All you need
is a tin can. It's gonna be a tin can eye. Take the ends out of both ends
of it. You need an elastic band and
a piece of waxed paper, and it's very easy to make. You
just put the wax paper over one end of the can like this
and pull it down so that it makes a nice tight drum.
And then just hold it on with the elastic band, so it's nice
and smooth like that. And then
You put the magnifying glass in front and you have an eye, believe it or not. Now if you want to see how it
works, come on around behind me. Now eyes like to look at something, so let's look at
something interesting like Mr. Bones over there. We hold the magnifying glass
up and. Wow, there he is. Look
that up. That's right, he's upside down. And do you
know that the lens in your eye actually makes the picture on the back of
your eye upside down, but your brain turns it the right way around.
But there's a full color picture. Now let's see if we can get a real face over
there. Naomi, do you want to go stand beside Mr. Bones and let's see if we can see
Naomi. There she is. It's here.
How are you doing? I waved the camera. Yeah, there she is on the
ceiling. That's right. So your eyes
are really complicated, aren't they? And they're very delicate too, and that's why they need to
be protected. That's why you have eyelashes, these little hairs that are
around your eyes, why you have eyelids so you can squint them close to keep out
dust and dirt and even too much light. There are other things you can
do to protect your eyes. If you read in
a dark place, your eyes become strained, and they get tired.
You might get a headache. So always make sure you have enough light when you
read. And whenever you're making something and pieces of
wood or metal or even paper might be flying around, use eye
protection. It's the same when you play sports or even when you're
just mowing the lawn. If things are flying around that could get into your
eyes, wear eye protection. Because your eyes are
very soft, you don't want to get anything in them that could scratch them.
Bob, Sarah, what's the matter? Why are you crying? I'm
not crying. I just got something in my eye. Something in your eye. Turn around here. Let
me see. Look up. Oh yeah, I think you've got a hair in it.
Just a minute. See if I can get it here with this tissue here. We'll wipe up your tear and just
turn around a little. Hey watch? There
There, I think I got it. Does it feel better? Yes, thank you. You're
welcome, Bob. Yeah, why am I cry when I
got something in it? Why did you cry? Well, that's your eye's way of
washing itself. You know, tears aren't just for crying. They're there all the time, and they keep your eye
nice and moist. And whenever your eye feels something in it like a piece of dirt or or
this hair that you got in there, and your eye turns the tears on and the
tears wash whatever it was away. Oh, so crying is
good sometimes, yeah, absolutely. See ya.
You know, Sarah did the right thing in telling me that she had something in her eye. If you ever get
something in your eye, tell an adult and don't try to rub it because that
could actually make it worse. Some people's eyes don't work very
well. They see the world kind of fuzzy like this, so their eyes need
help and they put on glasses, and the glasses
make everything clear. And they can see much better
Your eye has many parts. Muscles move your eyes up and
down and from side to side. The iris opens and
closes like a window shade to control the amount of light.
The hole in the middle of the iris is called the pupil. The
lens in your eye is clear and curved. It focuses the light on
the back of your eye. From there, a nerve carries the
message to the brain, and you can see. Everyone
should have their eyes tested. Glasses help many
people see better. Protect your eyes from anything that could
fly into them. Make sure you have enough light when you read.
And when you get something in your eye, tears can help wash it away.
Well, everybody, did you learn something interesting today? Yep, yep, a
lot. Great. Would you say that today's show was a real eye
opener? Get it? Yeah, get it eye opener.
Hey, come on, come on, it's a joke. It's funny. You're supposed to laugh. Hey, come on, everybody, eye
opener. Don't you get it? You know. Well,
