The primary function of crystallline lens is to adjust focus of eye on objects at different distances.This adjustment of focus is similar to the focussing of a photographers camera ,and is contolled by the nervous system which activate the muscles around the lens to alter its shape and hence refractive power.
So the answer is to adjustment of pupil.
What else can I help you with?
The human eye contains a lens what is it called?
The lens is also known as the aquula (Latin, a little stream, dim. of aqua, water) or crystalline lens. http://en.wikipedia.org/wiki/Lens_%28vision%29
What is the function of the hyaloid canal in the human eye?
The hyaloid canal in the human eye serves to provide a pathway for nourishment to the developing lens during fetal development.
What structure changes its shape to focus light at the back of the eye?
The lens of the eye also called the crystalline lens.
What part of the eye bends the light as it enters?
The crystalline lens is the part of the eye that bends/refracts the light rays as it passes through it.
How many lenses does the human eye have?
The human eye typically has one lens, which is located behind the iris. This lens helps to focus light onto the retina at the back of the eye, which then sends signals to the brain for processing visual information.
What is a crystalline lens?
A crystalline lens is the lens in the human eye.
Is the human eye has a double convex or a plano convex lens?
The human eye has a double convex lens in the cornea (outermost layer) and a bi-convex lens in the crystalline lens inside the eye.
What is the use of lens in your eye?
The crystalline lens in human eye is indispensable to perform refraction so as to enable us to see objects clearly.
What part of the human body is effected by cataract?
The eye.In the crystalline lens of the eye, specifically.

What part of the eye is similar to a contact lenses?
The part of the eye that is similar to a contact lens is the crystalline lens.
What are two examples of lenses that occur in nature?
A microscope and eyeglasses are two examples of scientific lenses.
What is the function of the muscles in the human eye?
The eye lens is kept in place by ciliary muscles. These muscles can contract or relax.If the ciliary muscles contract or relax the focal length of the eye lens becomes large or small.Or in other words the function of the eye lens is to increase or decrease the focal length of the eye lens.
Why is the eye of the squid called a camera eye?
A camera eye is an eye with a crystalline lens that focuses light. It is found in squid, octopi, and vertebrates. This is similar to the lens arrangement of a camera.
What is the function of the hyaloid canal in the human eye?
The hyaloid canal in the human eye serves to provide a pathway for nourishment to the developing lens during fetal development.

The lens of the eye also called the crystalline lens.
What is the descriptive word for lens of the eye?
Transparent, biconvex intraocular tissue that helps bring rays of light to a focus on the retina.
