Eye

The way that light enters your eye and gives a signal to your brain is by reaching into your cornea and passing through the lens. It gives your brain a signal by letting light enter the eye to see the image that your eye wants to see. It gives a signal and pathway by letting your brain know that it wants your eyes to visualize this image or object.

Light is really easy entering your eye, and by that i mean that your brain knows that the light that passes through the cornea and reaches your brain is letting an image enter your eyes and brain. The light intercepts with your eyes and brain.
