No, green eyes are not fake. Green eyes are a naturally occurring eye color that is caused by a genetic mutation. This mutation results in low levels of melanin in the iris, though more melanin than in blue eyes. The combination of low melanin and the way light scatters within the iris creates the green appearance.
While green eyes are often described as "rare," their prevalence varies depending on geographic location and ancestry. Green eyes are most common in Europe, particularly in Northern and Central Europe.
While green eyes are a real and natural occurrence, there are cases where individuals may wear colored contact lenses to alter their eye color. However, these are not true green eyes and are simply a temporary change.
