Welcome, everyone, to Studio Classroom Worldwide.
My name is Steve.
I'm so happy you've joined us today.
Thanks for watching.
We often hear warnings about how harmful the sun can be to our health.
As we should because the risk of skin cancer and heat exhaustion are real.
Now just a few months ago, we had an article about how to protect ourselves from
the sun.
Tucked away in that lesson was a quick tip that today we want to expand upon,
which is protect your eyes.
Today's SAFETY feature reminds us that wearing sunglasses is so much more than
just a fashion statement.
Let's jump into the reading now - The Sun Gets in Your Eyes - on page 38.
The Sun Gets in Your Eyes.
Wearing sunglasses is so much more than just a fashion statement.
Every time you look in the mirror, a pair of eyes looks back at you.
Those same eyes can see a glimmer from a candle from a distance of 14 miles.
They process 36,000 bits of information every hour and can distinguish 500
shades of gray.
Your eyes' intricate inner workings deserve as much protection as you can give
them, and wearing sunglasses outdoors is a very good way to start.
Whether you're hiking, watching a baseball game or walking on a city sidewalk,
don your sunglasses!
Why?
Exposure to the UVA and UVB in sunlight damages the eyes, leading to very
serious eye problems.
(Music).
Hi, everyone.
Thank you for joining us.
My name is Ryan.
And my name is Kaylah.
And today we're talking about the sun and how it gets in your eyes.
Wearing sunglasses is so much more than a fashion statement.
That's right, friends.
It's very important to make sure you're wearing sunglasses to protect your eyes.
Friends, sunglasses look like regular classes, but they are dark to protect your
eyes from the sun.
That's right.
And we like to wear sunglasses because we think they're fashionable, they make a
statement.
But they're much more and then just for fashion.
That's right, friends.
Every time you look in the mirror, you see a pair of eyes, a pair of eyes looks
back at you.
That's right.
A pair of eyes is looking back at you - those are your eyes.
So every time you look in the mirror, you need to be protecting those eyes.
Yes. And your eyes are incredibly powerful.
Those same eyes that you see staring at you in the mirror can see a glimmer from
a candle from a distance of 14 miles.
That is incredible when you consider how small a candle is, especially when you
consider how small a glimmer is.
Now Ryan, what is a glimmer?
OK. A "glimmer" is a very weak light that is not continuous.
It is always changing.
That's right. We could also call it a flicker.
So it kind of comes and goes, and it's very small.
So friends, we've all seen candles.
You know what a candle's flame does, it kind of comes and goes.
That is glimmering.
OK. Kaylah, you are also wearing very pretty hearings today.
That glimmer, light, shines off of them in a very small way.
Well, thank you so much.
I like my earrings too.
Now your eyes can see this small amount of light from 14 miles.
These are incredible.
Your eyes are amazing.
Yes. Now your eyes can also process 36,000 bits of information every hour and
can distinguish 500 shades of gray.
Wow! Your eyes are an important part of who you are.
Big or small, your eyes are incredible.
That's true.
Now we're talking about how much information your eyes can process.
That doesn't mean your eyes are thinking.
They are actually sending that information to your brain, 36,000 bits.
That's a lot.
I don't even know how much a bit would be.
Ryan, that's a lot of information.
Yes. Now a bit, friends, is a small section of information.
Your computer uses "bits" to measure how much information it is using.
And your eyes send 36,000 parts of information every hour and can measure 500
shades of gray.
That's incredible.
"Shades" are how light or dark something is.
So 500 of those means they're very close, but your eyes can tell the difference.
You might ask why is it so important that we know these facts.
Well, your eyes'... intricate inner workings and they... deserve much
protection.
Yes. They deserve as much as you can give them.
And one way to do that is to wear sunglasses outdoors.
That's right.
It's a very good way to start protecting your eyes.
Wear sunglasses!
Now you might be wondering: I just wear them because of fashion.
Or I don't like wearing them. They make my face look funny.
My head's all funny shaped... My nose is crooked. They sit weird.
But friends, your eyes are an important part of your body.
Please protect them.
Yes, because they are very intricate.
They have many different parts.
And you should protect them, friends, doesn't matter what you're doing.
Whether you're hiking, watching a baseball game or walking on a city sidewalk,
don your sunglasses!
OK. We see the word "don." That simply means to wear something and wear it
proudly.
"Don" also means to put them on.
So please, friends, put on, don your sunglasses, and wear them with pride.
But Ryan, why should you don your sunglasses?
Well, that's a very good question, Kaylah, because exposure to UVA and UVB in
sunlight can damage your eyes.
OK. We said that UVA and UVB can damage your eyes.
But you need to know what those are.
Well, the "UV" stands for ultraviolet radiation.
Now the "A" means the long waves.
And the "UVB" are the short waves.
Exactly.
And so you have to protect your eyes from both kinds of rays because they can
lead to very serious eye problems.
And you don't want eye problems, friends.
You know how important your eyes are.
So please, take the protection now.
Use your sunglasses now so that you're prepared for the future.
All right, friends, we'll give you more tips on why you should continue to
protect your eyes.
But right now, let's go to the Chat Room.
Hey, Ken.
Did you find another good book?
Well, it looks pretty good so far.
It's a book about marketing.
Oh, OK.
So you're tired of books about history and war?
Maybe just a little.
But I want to learn more about marketing.
I find it interesting.
I do too.
Well, I hope you enjoy the book.
Thanks, Bryan.
Say, I can't help but notice your tie looks kind of funny today.
That's not your usual style.
I must admit, Ken, I was in a hurry this morning, so I grabbed the first tie
that I found without really looking.
I'm sorry.
I'm not trying to make a fashion statement.
Make a fashion statement?
How could you do that?
You definitely do not look very fashionable.
Well, I can't deny that.
But what I meant is I'm not trying to attract attention on purpose or display
some personal style of mine.
Oh, good. I'm relieved.
Hey, speaking of fashion statements, there's a chapter in this book about
writing your own mission statement.
Do you have one of those, Bryan?
Not really.
I do have a sense of mission when it comes to teaching others, but I don't have
a specific mission statement.
Maybe the book is also talking about company mission statements.
Hey, don't all companies have the same mission to make money?
Maybe that is partially true, Ken.
But most companies have unique mission statements that define their goals and
their commitment to the communities they serve.
Some of those statements are a sentence or two while others are long paragraphs.
I'll have to check out a few of those and then try writing my own mission
statement.
I'd like to read that when you're done.
OK. I'll let you know.
