FASCINATING FACTS
Did you know ?
Your Sight.
Eyes are a bit like video cameras. A lens at the front projects the picture on to the back of the eye, called the retina, where millions of light-sensitive cells detect the picture and transmit it to the brain via the 'optic' nerve.
The eyes are two tough little balls filled with a jelly-like substance called vitreous humour. Each eye gives you a slightly different view of the world. The brain then combines these different views to give you a 3D picture.
