The art of vision......experience the extra time and care we take

Structure of the eye

 

The eye is shaped like a ball. Its tough white outer coat is called the sclera and its surface is covered by a thin skin (the conjunctiva). The outer coat is clear at the front of the eye and this area is called the cornea.

 

 

Behind the cornea is the iris - the coloured part of the eye - with the pupil forming a hole in its centre.

 

The space between the cornea and the iris is filled with a clear fluid, called 'aqueous humour', which maintains the pressure in the eye (the intraocular pressure).

 

The pressure is determined by a balance between the fluid entering and leaving the eye.

 

The Lens is situated behind the pupil and is responsible for adjusting the focus of light on the retina so that we can see clearly. The space between the lens and the retina is filled with a jelly called the vitreous gel; it is cellular debris and protein strands that move in this gel that we see as floaters. The optic nerve is the wire that carries all the images, that we call vision,

to the brain.
