Lens: anatomy, structure and function. | Kenhub

https://www.kenhub.com/en/library/anatomy/lens
The lens is an ellipsoid structure located in the eyeball. It lies posterior to the iris and anterior to the vitreous body. Moreover, the lens is encircled by the ciliary processes, and is attached to them by the zonular fibres. The lens is comprised of three main parts: capsule, epithelium and fibers. Although it has many layers, the lens is

The lens focuses images and can be affected by cataracts and aging. The lens is a curved structure in the eye that sits behind the iris. The lens' function is to bend and focus light to help you see images clearly. Because it's flexible and changes shape, it can help you see objects at varying distances.

2. STRUCTURE AND CELLS OF THE LENS. Weighing about 65 mg at birth, the human lens increases in weight to about 160 mg by the age of 10 at which time growth slows substantially so that it weighs about 250 mg by the age of 90. 6,7 As much as 60% of the total mass of the lens can be made up of proteins, much higher than almost any other tissue. 8 The lens is surrounded by a collagenous capsule

In humans, the lens is the organ with the ability to change morphology and refractive power, designated as accommodation, to focus light from various distances and obtain clear retinal image. The accommodative ability of the lens depends on its structure and biological parameters. The lens grows throughout the life, forming specific lens

Lens shape and structure. 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

The lens of the eye, also called the crystalline lens, is an important part of the eye's anatomy that allows the eye to focus on objects at varying distances. It is located behind the iris and in front of the vitreous body. In its natural state, the lens looks like an elongated sphere — a shape known as ellipsoid — that resembles a

The lens (crystalline lens), enclosed in its capsule, is situated immediately behind the iris, in front of the vitreous body, and encircled by the ciliary processes, which slightly overlap its margin.The capsule of the lens (capsula lentis) is a transparent, structureless membrane which closely surrounds the lens, and is thicker in front than behind. It is brittle but highly elastic, and when

Anatomy of Lens (OP7.1) The adult human lens is located behind the iris and pupil in the anterior compartment of the eye. The lens is held in place by zonules (suspensory ligaments) which run between the lens and ciliary body. The lens continues to grow throughout life. It is a unique characteristic not shared with any other internal organ.

Behind the anterior chamber is the eye's iris (the colored part of the eye) and the dark hole in the middle called the pupil. Muscles in the iris dilate (widen) or constrict (narrow) the pupil to control the amount of light reaching the back of the eye. Directly behind the pupil sits the lens. The lens focuses light toward the back of the eye.
