From a scientific perspective, green eyes are a fascinating example of how light and biology work together to create color. Contrary to how they appear, there is no actual green pigment present in the iris. Instead, green eyes form through a combination of low melanin levels and a naturally occurring yellowish pigment called lipochrome. When light enters the eye, it scatters across these pigments through a process known as the Tyndall effect, producing the green hue that people recognize. This interaction with light also explains why green eyes seem to shift in brightness or tone depending on the environment, making them appear almost chameleon-like in different settings.
