Why are blue eyed people more sensitive to pain?
One of the proteins the NCX-4 gene controls is related to pain. Additionally, genes related to melanin are also related to pain. Melanin is the pigment that makes eyes darker. This explains why people with darker eyes are more susceptible to pain.
Are blue eyes the most sensitive?
Did you know that blue eyes don’t contain any blue pigment? They appear blue due to how the light reacts with the structures of the iris.

How are eye color variations related to pain?

Why are people with blue eyes more light sensitive?
