**Core Concept**
The lens of the eye is a unique structure that lacks a layer of epithelial cells, which are typically present in other epithelial tissues. This absence is due to the lens's specific developmental and functional requirements.

**Why the Correct Answer is Right**
The lens epithelium, also known as the lens capsule, is replaced by a single layer of lens fibers produced by the differentiated lens epithelial cells. However, the lens itself does not have a continuous layer of epithelial cells like other tissues. This is because the lens is a non-keratinized, avascular, and avascular structure that requires a unique cellular composition to maintain its transparency and refractive properties.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the lens of the eye is avascular, meaning it lacks blood vessels, which is a critical factor in its transparency and refractive properties. This unique characteristic is essential for the lens to function properly in focusing light on the retina.

**Correct Answer: None**
