**Physics Problem: Optics and Refraction through the Cornea**

An object is placed **10.1 cm** in front of the cornea. (The cornea is thin and has approximately parallel sides, so the refraction that occurs as light travels from air to the cornea to the aqueous humor is essentially the same as though the aqueous humor were directly in contact with the air. The aqueous humor has an index of refraction \( n = 1.34 \) and the radius of curvature of the cornea is 7.8 mm.)

**(a)** What is the image distance for the image formed by the cornea alone?
   
   _(Input box for the answer)_

**(b)** The image formed by the cornea serves as an object for the lens. Treat the lens as a thin lens **8 mm** behind the cornea. Find the optical power of the lens necessary to form an image on the retina, **25 mm** from the center of the lens.

   _(Input box for the answer)_

---

In this problem, the focus is on understanding the refraction and image formation properties of the human cornea and its interaction with the lens of the eye. Utilize the principles of geometric optics, the lens-maker's formula, and the concept of optical power to solve these parts.
