The function of the vertebrate eye is unusual compared with other processes found within the body. For example, the direction in which sensory information flows is actually opposite to the path that light takes through the retina. Explain the sequence of events involved in the movement of light and information through the structures of the eye and explain why they move in opposite directions. Compare this sequence to the functioning of the Mollusk eye.
