The eye is one of the most complex organisms in the human body – second only to the brain
The human eye is a wonderful thing. Although small in size, the eye arguably provides us with the most important of our ﬁve senses – our vision. It is one of the most complex organisms in the human body – second only to the brain.
Despite being just over two centimetres in diameter, human eyes have over 2 million moving parts. They can distinguish over 500 shades of grey and over 2.7 million colours. Eyes are amazing.
