What part of the eye light pass through?

The colored part of your eye contains a lense, just like a camera or glasses. The light passes through it (thru the black hole in the center of your eye) and the image is projected on the back of your eye. Optical Nerves on the back of your eye "read" the light and colors and transmits that to your brain for processing.

It is also transmitted through refraction. google eyes and refraction for a better understanding of this. N btw. Who ever wrote the first paragraph cant spell and thinks you dont know what the pupil in your eye is. :)
