Green Eyes: Advantages, Disadvantages & More

Green eyes are the rarest color, with only 2 percent of the world population naturally having green eyes. The largest concentration of green eyes is found in Ireland and Scotland, where 86 percent of the population has blue or green eyes.

What Causes Green Eyes?

Green eyes are not caused by pigmentation, but by a lack of it. 

The color of the eye is determined by a pigment called melanin in the outer layer of the iris. In green eyes, the levels of melanin are lower than in brown or hazel eyes. 

Ultimately, eyes that have less melanin tend to look green or blue. Eyes that have more melanin appear hazel. Those with the most melanin are brown.

Individual eye color is determined by genetics. In the past, people believed that eye color depended only on a single gene. 

Recent genetic research now confirms there are 16 genes responsible for color. Due to these genetic variations, parents can give birth to children with different eye colors.

If your baby is born with blue eyes, there is a chance their eyes may change colors. Between the first few months or few years, your baby will produce more pigment, which may cause their eyes to turn green, hazel, or brown. 

How Common Are Green Eyes?

Green eyes are the rarest eye color in human beings. According to the World Atlas, only 2 percent of people in the world have green eyes. This rarity makes it a sought-after color.

People with green eyes are generally found in northern, central, and western Europe.

Green Eyes & Eye Health: Advantages & Disadvantages

As with all eye colors, some links have been made between green eyes and certain health conditions or traits.

Advantages of Green Eyes

A 2014 study from the University of Pittsburgh found that women with green or blue eyes may be able to handle pain better than women with brown or hazel eyes. Further studies are needed to draw strong conclusions on the association between eye color and pain tolerance.

People with green eyes are often considered creative and imaginative. This eye color is associated with jealousy and passion. Since it is rare, it is often deemed very attractive.

Disadvantages of Green Eyes

Green eyes, like blue and gray eyes, may have an increased risk for certain eye cancers. 

People with lighter eye colors may be more likely to develop cancer of the eye called uveal melanoma. The uvea is the middle layer of the eye. 

Melanoma of the uvea is an extremely rare disease. It affects about six in every 1 million adults in the United States annually. 

People with green eyes are also often fair-skinned, so they may be at greater risk for various forms of skin cancer as well.

An additional disadvantage of green eyes may be light sensitivity. If you have green eyes, you have less pigment in the iris. Due to this, it may be harder to block out sunlight or bright fluorescent light. As a result, your eyes may feel more sensitive to light.

How to Tell if You Have Green or Hazel Eyes

Green eyes are typically one solid color. Hazel eyes tend to be a mixture of colors such as green, brown, and golden.

If you see flecks of various colors in your eyes, including bursts of golds or browns, it’s likely that you have hazel eyes. If they tend to be less varied throughout, they are likely green.

Which Eye Color Is Considered the Most Attractive?

As green is the rarest eye color, it is not surprising that it is ranked as the most attractive eye color in many surveys and polls. In a 2022 survey of 66,000 people, 20.3 percent ranked green as the most attractive eye color.

Celebrities With Green Eyes

Celebrities with green eyes include popular stars, such as Adele, Kate Middleton, Scarlett Johansson, Gigi Hadid, Charlize Theron, Lindsay Lohan, Paul Rudd, Channing Tatum, Kate Hudson, and Emma Stone. 

How to Enhance & Change Your Eye Color

If green eyes are on your wish list, you’re in luck. It’s possible to shift your eye color with the use of colored contact lenses. Enhancing and changing your eye color with colored lenses is a fun way to play with color and explore your personality.  

Colored lenses require a prescription, so you’ll need to visit an optometrist first. This professional can help you evaluate the available choices and make a recommendation on which will help you accomplish your goals.

Depending on your original eye color, you can choose from different types of lenses. 

If your eyes are very light in color, you may be able to work with enhancement or tinted lenses. If you have a medium color, you may be able to let some of the color come through with a translucent lens. If your eyes are dark, consider using an opaque tint to get the desired effect.

Once you’ve got green eyes thanks to colored contacts, evaluate your clothing colors, hair color, and sunglasses. You may want to tweak some other things to match your new look.
