- Sorry, but no funny teaser today.
In fact, I'm about to get very serious for a few moments.
Not really.
Just last month we hit our three year anniversary,
launched our one hundred and twentieth video,
and surpassed the one and a half million views mark.
(explosion)
Thank you.
(crowd cheering)
We helped cover a lot of ground
in the last three years, but there's also a lot
that we haven't even begun to cover.
So as a reminder of some of the other amazing stuff
that you will find on the OpticianWorks website,
here we go!
Taking great measurements, step-by-step instructions
on getting good fitting heights,
how to get a great frame fit every time
using our one two three method,
dispensing basics and troubleshooting,
all about tinting,
low vision,
contact lenses,
sales,
sales in the work environment, business management,
company relations,
and an entire section
on vision care plans
including examples
of calculating customer out-of-pocket expenses.
So yes, the Laramy-K OpticianWorks YouTube chanel
covers so much great stuff,
but there is still plenty more to learn
over at the OpticianWorks website.
Please, check it out and here's a little taste.

Hello!
I would like to welcome you
to the Laramy-K OpticianWorks training center,
where we're gonna do something
a little bit different today.
On the OpticianWorks website, in the first course,
there's a lesson called "The Human Visual System".
It is an amazing piece written by
an optician
who became an optometrist.
In that section, Doctor Eric talks about his theory
of reverse projection and I wanted to bring that to video
to help you visualize the concept.
I'm sure you're all familiar with the projector.
That thing.
There, those.
They're everywhere now, right?
If you pop the top off of one of those,
that's what you have.
They are connected to a computer.
The computer is responsible for image generation.
You have a cable that connects
the computer to the projector,
and that goes through the motherboard,
and that's connected to the color processor,
and there is a light source.
Just like an old fashioned movie projector,
with film you still have a light source.
It's really intense bright, white light.
Usually have a couple of prisms,
you have one, two, or three of the color processors.
The prism breaks down your white light
into your component of red, green, and blue.
The color processor rearranges those
into something like 35 trillion different colors,
and all of your pixels
still going this way, pushing out into the theater.
You have a set of lenses.
The lenses are simply to allow us to adjust
the length from the projector to the screen,
and of course to focus the image
so you see it clearly.
Light's passing out, until it hits
this beautiful huge movie screen.
Twenty feet tall, thirty feet wide.
You get to sit in the audience,
and munch on your eighteen dollar popcorn,
and sip on your eight dollar coke
while you're watching your favorite movie.
So there's my screen, that's what I'm watching.
We are gonna take that,
and we're gonna turn it around.
Imagine if the white board
was your entire visual field.
Imagine when I'm standing in this one place
everything that I can see,
is the screen,
and I'm gonna take that screen, all that light,
all that information, all that color,
and I am gonna push it,
and focus it down
to go in your eye.
Gonna take all that information,
and I am gonna push it through
a hole in your eye as Doctor Eric says,
smaller than a dime.
We are gonna take
light and we are gonna reverse it.
It goes through.
This is the sunlight now.
We have a light source, right?
It's getting reflected off of objects in our world.
It's getting pushed into our eye.
Our eye has a series of lenses.
We have a cornea, we have aqueous humor,
we have crystalline lens, we have vitreous humor.
Then the light is gonna hit a combination of
the color processor in the motherboard.
That is our retina.
Let's call it now-
we've got our- this becomes a retina.
Two working together converts light,
'cause it's still light until it hits the retina.
Turns it into nerve impulses and chemical reactions,
and then it passes through,
not a cable, but what?
The optic nerve.
And what does that cable connect to?
It connects to our computer,
or our brain.
Our brain is our image generator.
It's why we say we see with our brains,
not with our eyes.
(upbeat music)
I love that.
Thank you for watching.
Please make sure that every-lings
in your reverse projection world
comes from Laramy-K.
