LENS CRYSTALLINA Meaning and
Definition
-
Lens crystallina refers to the transparent, biconvex structure located at the front of the eye, behind the iris. Also known as the crystalline lens, it is a crucial part of the eye's optical system, responsible for focusing light onto the retina. Its main function is to adjust its shape, thickness, and curvature in order to bend the incoming light and help produce a clear and focused image on the retina.
Lens crystallina is composed of specialized cells called lens fibers, which are organized in a highly structured and unique pattern. These fibers contain special proteins called crystallins, which provide transparency and maintain the lens' shape. The transparency of the lens is essential for allowing light to pass through it without scattering or being absorbed, ensuring optimal vision.
As we age, the lens crystallina gradually loses its flexibility, becoming less able to change shape and adjust its focus. This natural aging process, known as presbyopia, results in difficulty in seeing objects up close. Additionally, the lens may undergo various changes, such as clouding or hardening, leading to conditions like cataracts, where vision becomes progressively blurry and distorted.
Overall, the lens crystallina plays a vital role in the eye's ability to focus light and create clear images. Its transparency and flexibility are essential for maintaining good vision, and any alterations or impairments in its structure or function can significantly impact visual acuity.

Crystalline l., a transparent biconvex body lying between the iris and the vitreous, the principal refracting medium of the eye; it consists of a soft outer part (cortical substance) with a denser central part (nucleus). surrounded by a fine membrane (capsule).

Etymology of LENS CRYSTALLINA
The term lens crystallina is derived from Latin.
- Lens comes from the Latin word lens, which means lentil or lens. This is because the lens of the eye is shaped like a lentil.
- Crystallina is the feminine form of the Latin word crystallinus, which means crystalline or transparent like crystal. It refers to the transparent quality of the lens, which allows light to pass through.
Therefore, lens crystallina can be translated as crystalline lens.
