The journey of light is longer than you might think. The first step of light is when light is emitted from a light source like the sun. Next the light reaches your eye. Since there is many different parts of the eye, it has to travel through each part of the eye. Each different part has its own job to do.
Once the light reaches the eye the first thing that it will go through is the cornea. once it goes through the cornea, light passes through the aquaeous humor, then into the pupil. Next to goes into the Vitroues humor and in to the lens. One of the last this is the retina, this part flips the picture Finally the light reaches the optic nerve. The optic nerve send the picture to the brain and you see the picture.
