Will describe the pathway of light from the point where it enters the eye to the point in which the light information travels to the brain. briefly describe the structure and function of each organ along the pathway.

As it penetrates the eyeball, light first passes through the cornea, a transparent tissue that covers the anterior part of our eye similar to the glass of a watch. Following its path, the light now passes through the aqueous humor, reaching the iris-shaped pupil that functions like a diaphragm, immediately reaching the lens that acts as a focusing lens, then converging the light rays to a point on the retina. .

In the retina, over one hundred million photosensitive (light-sensitive) cells transform light into impulses conducted to the brain through the optic nerve. It is in the visual cortex, located in the back of the brain, where the processing of images received by our two eyes occurs, composing our "visual sensation".
