1. Visible Light and the Eye's Response - The Physics Classroom
The cones respond to the incident light by sending a message forward to brain, saying, "Light is hitting me." Upon reaching the brain, the psychological occurs: ...
Our eyes are sensitive to a very narrow band of frequencies within the enormous range of frequencies of the electromagnetic spectrum. This narrow band of frequencies is referred to as the visible light spectrum. Visible light - that which is detectable by the human eye - consists of wavelengths ranging from approximately 780 nanometer (7.80 x 10-7 m) down to 390 nanometer (3.90 x 10-7 m). Specific wavelengths within the spectrum correspond to a specific color based upon how humans typically perceive light of that wavelength.

The visual system is unique as much of visual processing occurs outside the brain within the retina of the eye. The previous chapter described how the light-sensitive receptors of the eye convert the image projected onto the retina into spatially distributed neural activity in the first neurons of the visual pathway (i.e., the photoreceptors). Within the retina, the receptors synapse with bipolar and horizontal cells, which establish the basis for brightness and color contrasts. In turn, the bipolar cells (the 2° visual afferent) synapse with retinal ganglion cells and amacrine cells, which enhance contrast effects that support form vision and establish the basis for movement detection. The information from the eye is carried by the axons of the retinal ganglion cells (the 3° visual afferent) to the midbrain and diencephalon. This chapter will provide more information about visual pathway organization and the visual processing that occurs within the brain.

The moment light meets the retina, the process of sight begins. About 60 years ago, scientists discovered that each vision cell’s receptive field is activated when light hits a tiny region in the center of the field and inhibited when light hits the area surrounding the center.

What is the visible light spectrum? The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.
