れらと異なってくる。The main factors that change the visual characteristics of the human eye are:
According to a recent study (Yoshinobu Naya: Proceedings of the 1986 Illuminating Society of Japan National Conference P, 75), it has been reported that the optical density of the human eye's crystalline lens (lens) is 0. The optical source 11 of the lens (lens) does not change much until the age of about 20, but after the age of about 20, it changes with age and the transmittance of blue light decreases, becoming yellowish and the transmittance also decreases. . Figure 3 shows this example:

In this way, the yellowing of the crystalline lens progresses as people get older, so the colors and brightness of objects seen by older people differ from those seen by younger people.
