Lens (vertebrate anatomy) - Wikipedia
The lens, or crystalline lens, is a transparent biconvex structure in most land vertebrate eyes. Relatively long, thin fiber cells make up the majority of the lens. These cells vary in architecture and are arranged in concentric layers.
Lens Cortex - an overview | ScienceDirect Topics
The harder central portion of the lens found in adults 30 years of age or older is called the nucleus of the lens and the outer lens fibers form the lens cortex. The harder nucleus is a product of the normal developmental growth of the lens.

Lens Cortex - an overview | ScienceDirect Topics
The lens substance is contained in the capsule and comprises the cortex and the nucleus of the lens (Fig. 14-36). The lens cortex is softer and contains more water than the lens nucleus.
Cortex: Thin and wispy, the cortex is like a layer of tape stuck to the inner aspect of the capsule. Using aspiration and vacuum power, it is peeled off at the end of the case. It requires no emulsification. Nucleus: Opaque, usually with an amber hue.
Cortex of lens - e-Anatomy - IMAIOS
The cortex of the lens is made up of soft cortical substance, it is softer than the nucleus because of its higher water content. There is no clear boundarie between the cortex and the nucleus of the lens.
Lens Biology and Biochemistry - PMC - PubMed Central (PMC)
The primary function of the lens resides in its transparency and ability to focus light on the retina. These require both that the lens cells contain high concentrations of densely packed lens crystallins to maintain a refractive index constant over ...
Lens Anatomy - The Cataract Course
The lens is a biconvex, avascular, noninnervated, encapsulated body composed entirely of epithelial cells and fibers. The 3 layers of the lens are the nucleus, cortex, and capsule. Lens transparency depends on tight, regular packing of lens fibers and their intracellular proteins to permit light transmission and provide refractive power for ...
Lens Nucleus - an overview | ScienceDirect Topics
The outer layers of fiber cells, known as the lens cortex, surround the nucleus and maintain some level of protein turnover and metabolic activity.
