What light does a chicken see?
The visible light we usually discuss is based on the spectrum that the human eye can see. The human eye can see many colors of light. However, our visual function only has one peak value. Even though you think you can clearly see a variety of light colors, The colorful world can distinguish different substances. That is only your feeling, not the feeling of animals. The colors of chickens are more colorful. In other words, the world you see is different from the world seen by animals. Based on the visual mechanism of the human eye,.
Benwei Lighting Technology Co., Ltd. analyzed the chicken's retina and mapped the chicken's visual response to light radiation into four radiation peaks. From this, it can be seen that the world that chickens see is far better than what we humans see. It is much brighter and brighter, and can see ultraviolet reflected light that is invisible to the human eye. In fact, people can also see the direct light of ultraviolet UVB and UVA, because it is defined as invisible light by international standards. Even if it is seen, it will seriously damage our eyes. The visual effect function limits our vision concept to the standard defined visible light range, but chicken vision is not subject to this limitation. The visual spectrum distribution of chicken is as follows:
The solid line in Figure 1 is the visual response curve of the chicken eye, and the dotted line is the visual effect function of the human eye. The spectrum that causes the visual response of the chicken is wider than that of the human eye, and has four peaks.
For intuitive memory, we add the colors recognized by the human eye to the chicken's visual map, as shown in Figure 2.
This picture clearly shows that the world seen by chickens is more colorful and brilliant than the world seen by human eyes. It is difficult for human eyes to identify false same-color pictures, but it is easy for chickens to distinguish. The visual effect of a single peak value of human eyes cannot be compared with that of chickens. Compare.
