Structure inside the eye that help to bring rays of light to a focus on the retina.
The flexible structure behind the iris that focuses the light rays to form an image onto the retina. When the lens does not focus properly, another lens has to be worn to supplement the cornea-lens focusing system. When the lens loses its transparency, the resulting condition is called a cataract.
a transparent disk located behind the iris which focuses light onto the retina. The lens has the ability to vary its power to accomodatively focus light from objects closer than optical infinity.
The natural lens of the eye, a transparent structure suspended behind the iris; focuses light rays on the retina and changes shape to change the focus of the eye from distance to near etc.
The second lens of the eye, behind the cornea.
Transparent body located behind the iris that focuses light waves on the retina.

Natural lens of the eye; transparent biconvex structure between iris and vitreous; action and accommodation allow change of focus from distant to near.
The crystalline lens is located directly behind the iris. It helps focus light on the retina as your focus changes from distance to near. Go to Top
The biconvex lens situated behind the iris of the eye. It is suspended from the ciliary body by a yoke of zonular fibers. By the force of the muscle fibers surrounding the lens its center thickness increases, its diameter decreases and the anterior portion bulges forward. This increases its dioptic power to focus the eye upon objects near to the eye. This act is known as accomodation.
the eyes natural lens that bends light (refracts) to provide some of the focusing power of the eye. The eye's natural lens is able to change shape allowing the eye to focus at different distances.
transparent double convex-shaped (outward curve on both sides) structure suspended between the posterior chamber and vitreous body
natural lens found inside the eye, adding approximately 17 diopters to the optical system (vision); responsible for adding diopters as needed to the vision optical system when viewing something nearby (accommodation); place where cataracts form; its failure is responsible for the condition called presbyopia. see diopter
is the lens inside the eye. It is biconvex in shape and provides some of the eyes refracting power. It is vascular and receives its nutrients form the aqueous humor. The crystalline lens is attached to the ciliary muscle found in the ciliary body via suspensory ligaments. Contraction of this muscle allows the lens to change its shape and therefore alter the power of the eye. The lens is transparent, although it can become opaque with age forming cataracts.
That portion of the eye which further refracts the light and focuses it on the retina.
The crystalline lens is the lens of the eye, serving to focus light on the retina, and changing its shape allows one to focus at near or far distance. Go to Top | Close Window

The lens of eye is located behind the iris and helps focus light on the retina.
The natural lens of the eye, located behind the iris, which helps bring rays of light to focus on the retina. The original state of the lens is transparent, but the lens becomes cloudy with age (cataract). The lens has the ability to vary its power to accommodatively focus light from objects closer than optical infinity.
The crystalline lens is a transparent structure that hangs behind the iris. It focuses light rays on the retina and changes shape, thus changing the eye's focus for different distances.

A transparent, colorless body located in the front third of the eyeball, behind the iris, that helps bring rays of light to a focus on the retina.
A transparent colorless body suspended behind the iris, the function of which is to bring the rays of light to a focus on the retina. It functions as a convex lens. Go to top of page
