Lens fibres

The lens fibers are cells without nuclei derived from the cells of the lens epithelium. They are arranged in concentric layers and compose the lens substance.

These fibers are derived from lens epithelium cells, which proliferate and migrate towards the equator lentis. Near the equator, these cells progressively elongate and lose their nuclei, creating new layers of superficial fibers that cause the lens to grow. The closer these fibers are to the center of the lens, the older they are, and the less curved and flexible they are. The fibers join the two poles of the lens, where they attach and form the radii lentis on both surfaces of the lens.
