What is "lens"?
The lens, a flexible and transparent structure in the eye, contributes to the process of focusing light onto the retina. It works in conjunction with the cornea to refract incoming light, allowing for the formation of clear images. By adjusting its shape, the lens accommodates varying distances, enabling us to see objects up close or at a distance with clarity. Its function is vital for visual acuity and the perception of depth and detail.

What is a "lens"?
A lens is an essential part of a camera that focuses light onto the image sensor or film, creating a sharp image. It is made of one or more curved glass elements that bend and direct the light rays. Different lenses can affect how a scene is captured, such as how much of the scene is included, how close distant objects appear, and how the background looks. Lenses are used to control focus, zoom, and depth of field, and they play a key role in determining the overall quality of a photograph.
