We all have  light pathway from the eye to the nerve system in the back of your eye, and you're probably wondering how it works. Well when you look at an image, all you see is it's official image. It's there you see it. How do you see it? Well when you look at the image your brain sees what it is. But when you look at light, it's a big difference. When you look at light, the light goes through your eyes to the optic nerve which is in the back of your eyes and then you can sense that it is actually light. With out that optic nerve you have in each of the back of your eye,you wouldn't be able to tell whether it's light or a color. When the light goes through your eye the nerves tell you that it is light, it's a signal for you to know.
          
                            When the light passes through your eyes, you can feel and know that it is a light. Your eyes aren't the ones that can tell you whether it's light or not. It's the optic nerves on the beck of your eyes. That's why when you look at the light, or when light shines towards you, you squint because it's so bright. Yeah, it isn't your eyes at all. It's the optic nerves that are in the back of your eye, which is telling you, or most likely giving you a signal that light is passing through your eyes, and that it is light.


                           Light is very difficult to explain, but in reality, light is like a color. People can see it with their own eyes. Light is there, it is a color. People
