The Rarest Eye Colors and How They Occur
| Eye Color | Cause(s) |
|---|---|
| Anisocoria | One pupil is larger than the other making one eye look darker. |
| Red or Pink | Little to no melanin due to albinism. |
| Violet | Lack of melanin mixed with light reflecting off of red blood vessels. |
What is the reason for different eye colors?
The colour of the iris is determined by the amount of melanin pigments, the way the melanin is distributed in the eye and the ratio of eumelanin to pheomelanin. Eye colours have been divided into nine categories and as many as 16 genes have been associated with eye colour inheritance.
What does it mean if your eye color is red?
Two major conditions cause a red or pinkish eye color: albinism and blood leaking into the iris. Although albinos tend to have very, very light blue eyes due to a lack of pigment, some forms of albinism can cause eyes to appear red or pink.
Why do brown eyes turn blue?
As you age, the structure and appearance of your body change. As your skin, bone structure, and hair color change due to aging, your eyes may change, too. It’s not unusual for blue-tinted rings to appear around your iris — the colored part of your eye. This condition is called corneal arcus.
Why do eyes have different colors in light?
This is the same reason why you sometimes appear red-eyed in photos. The eyes can appear violet in certain lighting conditions when the red color mixes with the bluish color resulting from light-scattering effects — basically for the same reason why the sky is blue. The table below shows how melanin content influences eye color.
Why do we have red and green colour vision?
Each of these now codes for a photoreceptor that can detect different wavelengths of light: one at short wavelengths (blue), one at medium wavelengths (green), and one at long wavelengths (red). And so the story goes our ancestors evolved forward-facing eyes and trichromatic colour vision – and we’ve never looked back.
Why do some people have violet or red eyes?
Lastly, people with albinism, a condition that causes a complete lack of or very low levels of pigment in the skin, hair, and eyes, sometimes appear to have violet or red eyes. Because albino people essentially lack pigment in the iris, light simply bounces off the back of the eye.
Why do people’s eyes change color when they are angry?
Some have suggested that mood can also change eye color. While it’s true certain emotions like anger or love can influence pupil size, the iris doesn’t really change color. When a person’s eyes have red, dilated blood vessels from anger, his eyes may appear to be greener because of the contrast, that’s all.
