Everyone's eyes are different

Apart from the colourblind, we all see colours the similarily. Scientists have prooved that the brain plays an even more significant role then we thought in deciding what we see. First of all, The retina is responsible in sensing colour and sending information to the brain. It cotains light receptors called cones and rods these receptors recieve light and convert it to chemical energy and activate the nerves which send messages to the brain. The rods are incharge of size, brighness and shape of images, wheras cones are responsible for fine detail and colour. There are around 7 million cones in the human retina, 64% are red and 32% green and 2% blue.
