The Rarest Eye Color in History: Green or Gray?

Have you ever wondered what the rarest eye color is? According to the American Academy of Ophthalmology (AAO), the answer is green. This hue has long been considered the rarest eye color, but recent classifications suggest that gray may be even less common. Around 10,000 years ago, everyone in the world had brown eyes. It is believed that the first person with blue eyes had a genetic mutation that caused their body to produce less melanin.

Today, approximately half of people in the United States have brown eyes. Those with this eye color may feel more at home when engaging in outdoor activities such as hiking, gardening, and camping. Although there is a lack of scientific evidence, it is highly likely that green is one of the rarest eye colors in the world. This may be disappointing news for some, but true violet or red eyes do not occur naturally in humans.

After that, the eye color will likely remain unchanged, and the only way to alter its appearance is through makeup, clothing, lighting, and colored contact lenses. Amber eyes are often referred to as wolf eyes due to their strong golden and yellowish color with a copper tint similar to that seen in wolves' eyes. People with this condition may have different colors inside an eye (for example, one half of the iris can be one color and the other half another). Since the concentration of melanin is very low, light scattering gives off a blue hue which mixes with pheomelanin's yellowish color to create a green shade.

In addition to melanin's light brown pigmentation, green eyes appear green due to a yellowish pigment known as lipochrome and an optical phenomenon called Rayleigh scattering. Compared to more dominant traits such as brown eyes, green eyes are among the rarest and most unique eye colors. The AAO advises against buying contact lenses without a prescription due to the increased risk of eye infections. For instance, your eyes may appear darker if you are wearing a blue shirt.

Some famous female celebrities with green eyes include Rihanna, Scarlett Johannsson, Gigi Hadid, Kate Middleton, Emma Stone, Adele and Charlize Theron. However, in natural light hazel eyes tend to have two very different colors inside the iris. As with blue and hazel eyes, green eyes are determined by a number of factors which science is still trying to understand. In other words, even if only one parent has brown eyes (considered dominant), it would be expected for their child to have this eye color.
