Light & Vision

Light is the medium that allows the human visual system to operate. With light we can see. Without light, we cannot. But the effects of light are more subtle than a simple on / off switch. Depending on the amount, distribution and spectrum of the light available, the capabilities of the human visual system can be enhanced or restricted. This chapter explains what light is, provides an introduction to the complexities of the human visual system and presents a summary as to how the capabilities of the human visual system are affected by lighting.
