      They actually send messages back and forth to each other quite a lot, where the brain tells the eyes how to behave. Did you know you see things upside down but your brain turns it the right way round? Your brain may catch something, give you an interest and cause you to look at it and then your eyes pick up the colour and your brain interprets the message of the eyes to give the right way up colour image we understand. Alternatively you could see something by accident. However, the light rays whcih are “seen” enter the eyes, not the brain – the brain just codes the colour to what we understand from it. “That bread is blue. I shall not eat it” and such forth.
