It is possible, though extremely rare, for humans to have purple or violet eyes. Purple eyes can occur naturally due to rare genetic mutations, low melanin levels, or certain medical conditions such as albinism or eye inflammation. These eyes often appear violet or lavender because of how light scatters in the eye combined with very low pigment in the iris. Purple eyes are not a common genetic trait and are estimated to occur in less than 1% of the global population. The color effect is often influenced by the interaction of light with the structures in the iris, especially when melanin is very low, making the eye appear purple or violet rather than typical brown, blue, or green. Additionally, purple or violet eye appearance can sometimes be caused by certain eye diseases or syndromes, but true natural purple eyes are among the rarest eye colors. Many people achieve the purple eye look through colored contact lenses or visual effects rather than having it naturally.
