THE SENSE OF SIGHT

The main organ of the sight are the eyes. Thanks to the sight we can see the colors , the size  and the shape of the things.

We need the light to see the things. Light enters the eyes in the pupil, the retina and the lens. 
To protect the eyes we have the eyesbrows, eyelash and eyelids.
There are people blind because they cant see.

PARTS OF THE EYE:

The parts of the eye are the sclera, the cornea, the pupil, the retina, the lens, the iris and optic nerve.

The size of the eye is approximately 2,5 centimeters.

If you can´t see well maybe you need glasses.
