Aspects of Camera Lenses: Adult Nucleus

Camera lenses are highly complex instruments that are based on the science of optics. Humans have been very familiar with optics even before we even knew what it was because our eyes follow those principals. In a way, the human eye is the most complex lens ever constructed. There are a lot of concepts about how our eyes work that can be paralleled to camera lenses. One such concept is the adult nucleus.

What Is the Adult Nucleus?

As humans grow from an embryo in their mother's womb to adults, their eyes grow with them. This development is broken up into stages called lens nuclei. There are four stages in this process. The first two take place in the womb. The third stage takes place from birth to puberty, and the last stage happens after puberty. The last stage when our eyes become fully developed is called the adult nucleus.

The Adult Nucleus and Camera Lenses

The adult nucleus concept can be seen as a parallel of the development of camera lenses. The first camera lenses would be considered primitive by today's standards, while today's lenses that employ autofocus and other motors to control aperture and shutter speed would be the adult nucleus of lens development.
