Alexandria’s Genesis is an online myth that states a genetic mutation involving purple eyes turns people into perfect beings. The claimed benefits of this mutation include:
While fictional, there are other real conditions that can cause eyes to appear purple.
Levels of melanin in the iris determine eye color. Because melanin is a brown pigment, people with more melanin tend to have darker skin, hair, and eyes.
All eye colors besides brown are due to an absence of melanin rather than any specific pigment.
When light hits the iris, this lack of melanin causes light to split into a color spectrum. Depending on how much melanin is there, eyes can appear green, hazel, blue, or purple.
Some eyes appear purple rather than blue due to the additional factor of light reflecting off red blood vessels.
This is a popular myth. Elizabeth Taylor’s eyes appeared purple in some photos due to factors such as lighting, makeup, and clothing. In reality, her eyes were blue, which can be seen in the vast majority of her photos.
True purple eyes are exceedingly rare. Less than 1% of the world’s population has them, making them rarer than blue, hazel, amber, grey, or green.6
Eye color ranges with the amount of melanin in the iris. The amount of melanin is, in turn, determined by genetics.
It’s possible that purple eyes could be the result of a mutation within the FOXC2 gene.1 This same mutation may also cause a disorder called Lymphedema-Distichiasis Syndrome. Symptoms include swelling of the limbs, double eyelashes, and heart problems.3, 4
People with lighter eyes are also more vulnerable to eye melanoma, also known as ocular melanoma.2
Complications from eye melanoma can include glaucoma, vision loss, and spread of the cancer to other parts of the body.
