The lens, by changing shape, functions to change the focal distance of the eye so that it can focus on objects at various distances, thus allowing a sharp real image of the object of interest to be formed on the retina.
The hyaloid canal in the human eye serves to provide a pathway for nourishment to the developing lens during fetal development.
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.
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.
The function of the lens is to focus light onto the retina at the back of the eye. It adjusts its shape using ciliary muscles to help the eye see objects at different distances by changing its focal length.
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
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.
The hyaloid canal in the human eye serves to provide a pathway for nourishment to the developing lens during fetal development.
A crystalline lens is the lens in the human eye.
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.
The pinhole camera has no lens. The human eye has a variable-focus lens.

It is lens. The lens consists of the lens capsule, the lens epithelium, and the lens fibres.

Eye piece and . . .lens ;-)
first learn about the power of each elements of human eye like cornea, lens...then we can get the commercial lens and can be mounted in mechanical assembly.
