Their pupils are bright yellow and golden yellow, which are very similar to those of wolves, so they are also called "wolf eyes" or "cat eyes". Refer to the wolf's eyes. They are bright golden yellow, but they look strong. These are amber eyes.
Pupil color correlation:
The color of eyes has been formed in human childhood, and it remains basically the same for life. However, the eye color of a few adults will obviously become darker or lighter with age.
It is the melanin in the anterior matrix of iris that determines the color of human eyes. The more melanin, the darker the human eye, and vice versa. However, the melanin content in the matrix usually remains unchanged for life, unless something abnormal happens to cause it to change permanently.
It is eye diseases, such as glaucoma, that change the melanin in the eyes. Secondly, color eyes caused by trauma (also known as binocular heterochromia), mainly manifested as different colors of eyes.
Finally, heredity is also the cause of eye color change. 10% to 15% twins' eye color will gradually change in adolescence and adulthood, which proves that twins with similar genes have the same probability of eye discoloration.
