Increased Sun Exposure Even if your eye color has set, your eye color could slightly change if you expose your eyes to more sunlight. As a result, your eyes might appear a darker shade of brown, blue, green, or gray, depending on your current eye color. Sunlight can also reveal colors that were already in your eyes.
Sun exposure can cause your eyes to produce more melanin, resulting in slightly darker eye color. However, the sun cannot dramatically change the color of your eyes. This melanin production appears as small brown spots on the iris.
Iris Color Changes
Iris freckles are small brown spots on the surface of the iris that are often related to sun exposure. They're common and usually harmless, like freckles on the skin.
The short answer: no. The pigment melanin determines your eye color. Eyes with a lot of melanin will be naturally darker. The less melanin in your eyes, the lighter they'll be.
While brown eyes contain more protective melanin pigment, they are still susceptible to eye sunburn and long-term damage.
Sun exposure can cause your eyes to produce more melanin, resulting in slighter darker eye color. However, the sun cannot dramatically change the color of your eyes. This melanin production appears as small brown spots on the iris.
In most people, the answer is no. Eye color fully matures in infancy and remains the same for life. But in a small percentage of adults, eye color can naturally become either noticeably darker or lighter with age. What determines eye color is the pigment melanin.
High melanin levels: Some people, especially Blacks, have higher-than-normal amounts of melanin in the body. They are more likely to be born with the brown spots on the sclera, the white part of the eye. Sun exposure: A mass of melanocytes can form on your eyes later in life, causing brown or dark spots.
In general, it's rare for eyes to change color. They may appear to change when your pupils dilate or shrink, but this occurs because the pigments in the irises come together or spread apart. In some cases, eye color can darken slightly during puberty or pregnancy, or as you reach your later years.
Babies are usually born with light blue or gray eyes, yet as they grow, their eyes often get darker. This is because eye color is determined by your genes and the melanin level on your body.
Green Eyes
Green is considered by some to be the actual rarest eye color in the world, though others would say it's been dethroned by red, violet, and grey eyes.
brown eyes are so beautiful, especially in the sunlight; they become a warm honey/whiskey colour.
People often confuse hazel with brown eyes because of the nearly similar hues. Although rare, hazel eyes have the second-highest concentration of melanin, making them appear light brown in some environments. Typically, hazel eyes take the color of a hazelnut — a mixture of green and brown.
Lighter-colored eyes have less pigment to protect against sun damage and UV radiation compared to darker-colored eyes. This means that people with green, hazel, or blue eyes are more sensitive to light and more susceptible to UV damage.
In sunlights, the pupil constricts and the iris stretches and the melanin pigments also stretch over a larger area and the color of the eye appears to become lighter in color.
They Are Less Prone to Certain Eye Diseases
The sun can cause severe eye damage and result in eye diseases like cataracts and macular degeneration. But because brown eyes have more melanin, it's safe to say that if you have brown eyes, you are less likely to get these types of eye diseases.
Benefits of Brown Eyes
People with brown eyes tend to be at lower risk for eye cancer, macular degeneration, and diabetic retinopathy. An additional benefit of brown eyes is that the higher melanin levels may protect the brain's nerves from damage due to noise.
Yorkshire-based iridologist John Andrews said: "Alas, it is a misconception that eyes change color with diet. It is a scientific impossibility." Yvonne Davis, an iridologist from London, was similarly skeptical but explained how the color change could potentially have happened.
Our eye colors don't typically change. However, clothing and makeup options bring out different shades of our eyes and make them pop. For example, blue eyes may appear bluer when people wear warm-toned eye makeup—and green eyes may appear more vibrant when wearing a green shirt.
In some cases, there are shades of gray, blue, and gold within the iris too. Brown eyes may also have some green in them. However, it is not nearly as noticeable as it is when someone has hazel eyes. With brown and hazel eyes, the other colors may appear as rings or flecks of color.
Your eyes turn yellow when there's a buildup of bilirubin. Bilirubin is an orange-yellow substance that's made during the normal breakdown of red blood cells. It is usually eliminated by your body. But if this process is slowed, bilirubin accumulates in your tissues, including the eyes, turning them yellow.
Much like gray eyes, hazel eyes may appear to “change color” from green to light brown to gold. Individuals whose eyes appear to be one color closest to the pupil, another color a little farther our, and another color around the edge of the iris are likely to have hazel eyes.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
What ethnicity has hazel eyes? Anyone can be born with hazel eyes, but it's most common in people of Brazilian, Middle Eastern, North African, or Spanish descent.
