Lesson Heading

How we see	play_circle pause_circle
An eye is like a living camera.	play_circle pause_circle
It detects light from surrounding objects.	play_circle pause_circle
It focuses the light to a picture which is understood by the brain.	play_circle pause_circle
The picture that travels to the back of your eye is upside-down.	play_circle pause_circle
Your brain turns it the right way up.	play_circle pause_circle
How the eye works	play_circle pause_circle
The diagram shows a human eye.	play_circle pause_circle
The human eye is approximately 2.54cm wide, 2.54cm deep and 2.3cm tall.	play_circle pause_circle
Each part of the eye has a different purpose.	play_circle pause_circle
First, light passes into your eye through the pupil.	play_circle pause_circle
In bright light it is smaller because less light is needed to see objects.	play_circle pause_circle
It becomes bigger in dull light so that more light enters the eye and helps you to see objects more clearly.	play_circle pause_circle
The iris controls the amount of light that enters the eye.	play_circle pause_circle
Muscles in the iris make the pupil larger or smaller.	play_circle pause_circle
The iris is the coloured part of your eye.	play_circle pause_circle
Next, the light passes through the lens.	play_circle pause_circle
The lens focuses light onto the retina.	play_circle pause_circle
The lens changes shape to make sure that the picture on the retina is as clear as possible.	play_circle pause_circle
The retina acts like a movie screen and shows the picture you are seeing-upside-down.	play_circle pause_circle
It turns the picture into an electrical message for the brain.	play_circle pause_circle
Finally, the optic nerve sends electrical messages from the retina to the brain.	play_circle pause_circle
The brain turns the image the right way up.	play_circle pause_circle
The eye's built-in protection	play_circle pause_circle
The cornea is the transparent skin that covers the front of your eye and protects it.	play_circle pause_circle
In particular, it protects the iris.	play_circle pause_circle
The outside of the eyeball is protected by the sclera.	play_circle pause_circle
It is made of tough skin that covers all parts of the eye except the cornea.	play_circle pause_circle
It supports and protects the eye.	play_circle pause_circle
Our amazing eyes	play_circle pause_circle
Humans have binocular vision. That means that both eyes work together.	play_circle pause_circle
They are placed at the front of our heads and we are good at telling how far away something is and how fast it is moving.	play_circle pause_circle
In the past, our vision helped us to hunt in order to survive.	play_circle pause_circle
We no longer hunt in the same way but we use our vision to help us in many different ways in our daily lives.	play_circle pause_circle
With your eyes you can see an object as small as 0.1mm across.	play_circle pause_circle
You can tell the difference between 10 million different shades of colour.	play_circle pause_circle
It seems impossible, doesn't it?	play_circle pause_circle
Our eyes are important and they need protection from damage and injury.	play_circle pause_circle
Natural eye care	play_circle pause_circle
Your eyelids and eyelashes protect your eyes.	play_circle pause_circle
Eyelids can partly close and act as sunshades in bright light.	play_circle pause_circle
They can shut out light completely when you sleep.	play_circle pause_circle
They can close automatically if something is flying towards your eye.	play_circle pause_circle
Your eyelashes trap dust that flies into your eye.	play_circle pause_circle
Tears wash your eyes. There are tear glands inside the upper eye lid.	play_circle pause_circle
Tears form all the time and blinking spreads the tears across your eye to help keep them clean and comfortable.	play_circle pause_circle
Extra eye protection	play_circle pause_circle
Very bright light can harm your eyes.	play_circle pause_circle
This girl is wearing sunglasses.	play_circle pause_circle
When she goes into bright sunlight, her eyes will be protected by the dark lenses.	play_circle pause_circle
Small pieces of hot or sharp material can injure your eyes.	play_circle pause_circle
This man is working with hot metal.	play_circle pause_circle
When he welded two pieces together, the sparks began to fly.	play_circle pause_circle
His eyes were protected by the thick plastic in the visor of his helmet.	play_circle pause_circle
Goggles have been worn by motorcyclists for more than 100 years.	play_circle pause_circle
They give protection from the wind, from insects and from dust.	play_circle pause_circle
Baseball catchers wear batting helmets with a metal visor to protect their eyes from the ball.	play_circle pause_circle
It's not surprising, is it?	play_circle pause_circle
In a baseball game, the ball can travel at up to 160kph. Ouch!	play_circle pause_circle
