What is the difference the type of lens used in camera and in human eye?

Aside from the obvious with respect to tissue versus glass, the camera lens is a compound lens made up from several lens elements each having different characteristics. Some of these elements converge light rays and some diverge them. Also, a lens element cannot precisely focus all the colors of light at the same point because they have different wave lengths. Thus lens design has to compensate for this as much as possible. Lens coatings must be employed to minimize diffraction, dispersion and glare. As for focus, the position of the elements relative to the film plane has to change with the change in distance from the subject.
I am no eye expert, but I believe the eye lens is much simpler in that it is one bioconvex element. It focuses by changing shape through the affect of muscles acting upon it. Certain deficiencies such as astigmatism, are corrected with glasses or contact lenses. It also cannot precisely focus all light wavelengths. How we deal with that as humans is interesting reading, but is far too complicated and unrelated to deal with here.

What type of image is formed by the lens of a camera?
a upside down image is formed in your camera then flipped around when it is seen by the human eye -Monica Magallon
How to use a 35 mm lens in a 16 mm camera?
You need to buy an adaptor. Make sure you specify exactly the type of lens and exactly the camera you want to attach it to. Don't forget that there will be a large increase in magnification, i.e. your 35mm lens will give more telephoto effect on a 16mm camera. It is unlikely that the automatic functions (aperture, focus) of the lens will be carried into the 16mm camera.
Does camera lenses have long or short focal points?
The short focal length of a camera lens is so that the image the lens forms is small and can be focused on a piece of light-sensitive film.
What is camera glass called?
Focusing screen, in it's simplest form. Fresnel lens (a type of focusing screen)
What does 55mm camera mean?
The question likely pertains to 55mm as a lens focal length, and does not relate to any type of camera. Another use for numbers like 55mm in connection with a lens is to designate the thread size of the filters and lens caps that lenses require. For the interchangeable lenses used on 35mm SLR cameras, those sizes commonly run from 49mm to 72mm. Cameras are designated by film size or by type. Some common camera designations are 35mm; SLR; rangefinder; digital; point-and-shoot; medium format; view camera; press camera (various types); TLR twin lens reflex) -- there are others. If there is a "55mm"camera, I haven't encountered it.
What type of lens do a camera use?
There are a few camera lens types such as : a wide angle lens (used to capture a larger area than the area visible by a human eye), telephoto lens (opposite of wide angle), panoramic lens and so on.

What is the typical diameter of a camera lens?
This really depends on the type of camera you are looking at. If you are looking at a professional camera, chances are the lens will be much bigger than an average family camera. However, most average-sized cameras have around 50 mm lens.

What type of device forms images through refraction?
Any device containing a lens, such as a camera or projector, or one which uses prisms such as a periscope.

The short focal length of a camera lens is so that the image the lens forms is small and can be focused on a piece of light-sensitive film.
