SIGHT is the perception of light.
It allows us to build up an image of what the world looks like around us. Tiny amounts of light are picked up by specialised cells in the back of our eyes and electrical signals are sent to the brain, where the information is decoded and turned into an image. But this perception is just one way of seeing the world - every animal sees a different picture.

Each animal’s eyes are built and wired into the brain differently, so the world can look very different, depending on which pair of eyes you are viewing it through. Animal eyes are tuned differently to ours, so some see fewer colours than we can, while others are able to see colours of light that we cannot even imagine. In this series, we find out how an Arctic predator’s snow-white camouflage is foiled by the eyes of its prey that can see a colour completely invisible to us, and how for small monkeys, sometimes seeing less colour is critical for them seeing their tiny prey.
Some creatures are able to see in better resolution than we can, as their eyes pack in more light receptors in their eye, while others can discern events that happen in the blink of an eye - far too quick for a human to spot. We also find out how creatures have come up with elegant solutions to see in places where there is no light - animal’s that can ‘see' with heat, and others that create light all of their own.
