Albinism results from the body's inability to produce sufficient melanin, the pigment responsible for coloring skin, hair, and eyes. While many people associate albinism with red eyes, this isn't always the case. The appearance of red or pink eyes is due to the lack of melanin in the iris, the colored part of the eye. This lack of pigment allows the blood vessels behind the iris to be visible, giving the eyes a reddish or pinkish hue. The eyes aren't actually red; the red appearance is a result of the underlying blood vessels showing through. It's important to note that some individuals with albinism may have eyes of different colors, such as light gray or violet, depending on the specific type and severity of the condition.
Understanding the Misconception
A common misunderstanding is that all people with albinism have red eyes. This is inaccurate. The color of the iris in individuals with albinism varies. While the lack of melanin often leads to the visibility of blood vessels, resulting in a reddish or pinkish appearance, other variations in eye color are possible. The Mayo Clinic notes that with albinism, the irises usually lack sufficient pigment, allowing light to shine through. (https://www.mayoclinic.org/diseases-conditions/albinism/symptoms-causes/syc-20369184) The Albinism Fellowship of Australia further clarifies that the iris color can range from light gray or violet to other shades, contradicting the common assumption of solely red or pink eyes.

The Role of Blood Vessels
The visible blood vessels are key to understanding the apparent red eye color. As stated in one source, "the blood vessels inside can show through the colored part (the iris), and the eyes can look pink or red." ([Source from 09-Nov-2022]) The lack of melanin pigmentation allows the underlying blood vessels to be easily seen, creating the illusion of red or pink eyes. This is consistent across multiple sources emphasizing the lack of pigment as the primary reason for the reddish appearance.
Variations in Albinism and Eye Color
It is crucial to remember that albinism isn't a single condition; different types exist, each impacting melanin production differently. This variation in melanin production leads to a range of eye colors in people with albinism, not solely red or pink.
