Key Stage 1

Meaning

 
A human eye.

Eyes are the part of the body that allows us to see.

Singular Noun: Eye
Plural Noun: Eyes

About Eyes

Most animals have only two eyes but some have more and some have no eyes at all.
Eyes allow us to see colour.
Eyelids blink a couple of times every minute to keep our eyes moist.
Eyelashes are there to stop dust getting in our eyes.
A person whose eyes don't see is called 'blind'.
Your eyes can be damaged and make you blind if you stare at The Sun.

Examples

 
 
A cat eye. The eye of a goat.
 
 
A chamelion's eye. A crocodile eye.


Key Stage 2

Meaning

Eyes are the part of the body that allows us to see.

About Eyes

Most animals have only two eyes but some have more and some have no eyes at all.
Eyes allow us to see colour.
Eyelids blink a couple of times every minute to keep our eyes moist.
Eyelashes are there to stop dust getting in our eyes.
A person whose eyes don't see is called 'blind'.
Your eyes can be damaged and make you blind if you stare at The Sun.

Key Stage 3

Meaning

 
A computer generated cross section of a human eye.

The eyes are a pair of sensory organs which allow us to see.

About Human Eyes

The eye is made of several parts:
  • Retina - Detects light.
  • Optic Nerve - Sends electrical signals from the eye to the brain.
  • Lens - Focuses the light onto the retina.
  • Iris - The coloured part of the eye.
  • Pupil - The hole in the iris that allows light into the eye.
  • Cornea - The outer protective layer of the eye.
 
A diagram of the eye.

Focusing Images

The eye uses a lens to focus an image on the retina.
When the lens does not work well enough people can use glasses.
 
The lens refracts the rays of light to form an image of the object.

Key Stage 4

Meaning

 
A computer generated cross section of a human eye.

The eyes are a pair of sensory organs containing receptor cells which can detect light.

About Human Eyes

The eye is made of several parts:
 
A diagram of the eye.

Defects of the Eye

The eye uses a lens to focus an image on the retina.
When the lens does not work well enough people require corrective lenses.
 
 
The lens in the eye of a person with myopia focusses the light from distant objects in front of the retina creating a blurred image. A myopic person can place a concave lens in front of the eye to correct their vision.
 
 
The lens in the eye of a person with hyperopia focusses the light in behind the retina creating a blurred image. A hyperopic person can place a convex lens in front of the eye to correct their vision.
