**Core Concept**
The point of refraction in the eye refers to the location where light is focused as it passes from one medium to another, specifically from air into the eye. This occurs at the cornea and the lens, where the light is bent due to the change in refractive index.

**Why the Correct Answer is Right**
The point of refraction in the eye is crucial for clear vision, as it determines the focal length of the eye. The cornea, being the first refracting surface, is responsible for about 2/3 of the total refraction, while the lens contributes the remaining 1/3. The cornea's refractive power is determined by its curvature, which is why it is the primary refracting surface in the eye. The correct answer is the cornea, as it is the primary site of refraction in the eye.

**Why Each Wrong Option is Incorrect**
**Option A:** Not a valid answer, as there is no such point of refraction in the eye with this name.
**Option B:** The lens is a secondary refracting surface, and while it plays a crucial role in accommodation and focusing, it is not the primary point of refraction in the eye.
**Option C:** Not a valid answer, as there is no such point of refraction in the eye with this name.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the cornea is the primary refracting surface in the eye, accounting for about 2/3 of the total refraction. This is why corneal abnormalities, such as astigmatism, can significantly impact vision.

**Correct Answer: C. Cornea**
