What parts make up the eye system? List each part and describe the function.
Understand the Problem
The question is asking for a detailed breakdown of the components that constitute the eye system, along with explanations of their specific functions.
Answer
Cornea, Pupil, Lens, Retina, Iris, Sclera, Macula, Optic nerve
The eye system consists of several parts: Cornea (clear outer part for focusing light), Pupil (opening for light entry), Lens (focuses light on retina), Retina (converts light into neural signals), Iris (controls light entry by adjusting pupil size), Sclera (white protective casing), Macula (central vision), and Optic nerve (transmits signals to brain).

More Information
Each part of the eye plays a unique and crucial role in the process of vision. For instance, the cornea and lens work in tandem to focus light accurately onto the retina, while the macula specializes in detailed central vision.
Tips
Avoid confusing the lens and the cornea—they both focus light but are distinct structures. Also, remember that the retina is the light-sensing part of the eye, not the lens.
