People with lighter eye colors, such as blue or green eyes, may be more sensitive to light compared to those with darker eye colors, such as brown eyes. This sensitivity to light is due to the level of melanin in the iris, which helps to block out excessive light. People with lighter eyes have less melanin in their iris, making them more susceptible to bright lights and glare. This sensitivity can cause discomfort, squinting, and even headaches in some individuals. It is important for those with lighter eyes to wear sunglasses or seek shade when exposed to bright sunlight to protect their eyes from potential damage.
