  1. lens cortex

    The lens, or crystalline lens, is a transparent biconvex structure in most land vertebrate eyes. Along with the cornea, aqueous and vitreous humours it refracts light, focusing it onto the retina. This adjustment of the lens is known as accommodation (see also below). In many land animals the lens can accommodate by altering its shape to change the focal length of the eye allowing them to focus on objects at various distances. The accommodation allows a sharp real image of the object of interest to be formed on the retina. In many fully aquatic vertebrates such as fish other methods of accommodation are used such as changing the lens's position relative to the retina rather than changing lens shape. Accommodation is analogous to the focusing of a photographic camera via changing its lenses. In land vertebrates the lens is flatter on its anterior side than on its posterior side while fish the lens is often close to spherical. Accommodation in humans is well studied to allow artificial means of supplementing our focus such as glasses for correction of sight as we age. The refractive power of a younger human lens in its natural environment is approximately 18 dioptres, roughly one-third of the eye's total power of about 60 dioptres at infancy and 10 dioptres by the age of 25 years. Most of the reduction in our natural accommodation as we age is attributed to the aging of our lenses.


  1. lens cortex

    The lens cortex is the outer layer of the eye lens, located between the lens capsule and the inner part known as lens nucleus. Heavily composed of fibers and cells, it helps the lens to maintain its shape and plays a vital role in focusing light onto the retina to facilitate clear vision.
