Light eye color refers to shades such as blue, green, and hazel that have less melanin in the iris compared to darker colors. This reduced melanin results in a lighter appearance, which can vary in intensity and hue. Light-colored eyes are often more sensitive to bright light due to the lower pigment levels. The genetics of eye color is complex, involving multiple genes that influence melanin production. Light eye colors are less common globally, with higher prevalence in certain populations, particularly those of European descent. Environmental factors and health can also affect the appearance of eye color over time.
