Foldable lesn is made up of –
**Core Concept**
The question pertains to the composition of the lens in the human eye, specifically the type of fibers that make up the lens. The lens is a clear, flexible structure behind the iris and the pupil, responsible for focusing light on the retina.
**Why the Correct Answer is Right**
The lens in the human eye is made up of a unique type of cell called lens fibers, which are composed of **elastin** and **collagen**. These fibers provide the lens with its flexibility and ability to change shape in response to changes in the eye's focusing needs. The lens fibers are arranged in a specific pattern, with older fibers in the central part of the lens and younger fibers towards the periphery. This arrangement allows the lens to maintain its shape and function throughout life.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not accurately describe the composition of the lens fibers. While the lens is indeed a critical component of the eye, its fibers are not made up of this material.
* **Option B:** This option is incorrect because it is a type of protein found in connective tissue, but it is not a primary component of lens fibers.
* **Option C:** This option is incorrect because it is a type of fiber found in muscles, not the lens.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that the lens in the human eye is a unique structure that changes shape in response to changes in the eye's focusing needs. This ability is crucial for maintaining clear vision throughout life.
**Correct Answer:** C.
