As an expert in genetics and human eye color, I can tell you that
violet eyes are indeed quite rare. Eye color is determined by variations in a person's genes, specifically the
melanin content and distribution in the iris. Most people have brown, blue, green, or hazel eyes, which are all more common than violet eyes.
The rarity of violet eyes is due to the fact that they require a very specific combination of genetic factors. They are often associated with a low melanin content in the iris, which allows more light to scatter in the front layer of the iris, creating a violet appearance. However, this is not a scientifically agreed-upon explanation, and the exact genetic mechanism behind violet eyes is not well understood.
Moreover, the perception of eye color can be influenced by the lighting conditions and the surrounding colors, which can make violet eyes seem even rarer than they actually are.
