The lens is a transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina. 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 lens of the eye focuses light and allows you to see. In this lesson, you will learn what the lens is made of and how it changes shape so that...
The objective lens is the main microscope lens used to magnify tiny objects or examine minute specimens that are a part of larger objects that are otherwise invisible to the naked eye. Other lenses simply provide additional fine focus or illumination. Most microscopes have four objective lenses, and each provides a varying level of magnification.
A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
