Hazel eyes are relatively rare, with only about 5% of the global population having them. In the United States, about 18% of people have hazel-colored eyes. Hazel eyes are created by a combination of melanin in the iris and Rayleigh scattering, which causes the inner part of the eye to sometimes appear lighter and the outer portion to appear darker.

There are no specific ingredients or materials associated with hazel eyes, as they are a natural eye color. However, people with hazel eyes may be more susceptible to sun damage and vision problems due to their lighter color.

In summary, hazel eyes are a unique eye color that is a combination of brown, green, and gold. They are relatively rare, with only about 5% of the global population having them. There are no specific ingredients or materials associated with hazel eyes, and they do not have any negative attributes.
