What Causes Brown Eyes? - High Concentration of Melanin

The color of your eyes is influenced by the amount of melanin in the iris. Melanin is a pigment that is responsible for the coloration of various tissues in the body, including the skin, hair, and eyes.

Eyes with a low concentration of melanin tend to appear blue or grey. As the amount of melanin increases, the color can shift towards green, hazel, or light brown. When the iris contains a high concentration of melanin, the eyes typically appear medium or dark brown.

Benefits of Brown Eyes, plus Disadvantages

Benefits of Brown Eyes

Brown eyes may offer greater protection against certain eye diseases. The higher levels of melanin in brown eyes are suggested to contribute to a lower risk of eye conditions such as eye cancer, macular degeneration, and diabetic retinopathy, according to the American Academy of Ophthalmology.

Disadvantages of Brown Eyes

Brown eyes seem to be associated with a higher risk of developing cataracts. According to the American Academy of Ophthalmology, an Australian study indicated that the risk of cataracts might be twice as high for people with brown eyes compared to those with different eye colors. However, the specific reasons for this higher risk have not been conclusively determined.

3. How do brown eyes look in the sun?

The sun's rays can stimulate the production of melanin, the pigment responsible for eye color, and cause brown eyes to change. They may look darker or shift in color towards hazel or green.

4. Are brown eyes dominant?

Yes, in terms of eye color inheritance, brown eyes are often considered dominant. This means that if an individual inherits one copy of the brown eye gene from either parent, their eyes are likely to be brown.

5. Do brown eyes have a limbal ring?

Certainly! Most people are born with a limbal ring in their eyes, even those with brown eyes. However, as we age, limbal rings often become less prominent. If you wish to enhance or bring back the appearance of limbal rings in your eyes, consider trying TTDeye limbal ring contacts.

6. Brown eyes are less sensitive to sunlight.

The increased density of pigment in brown eyes acts to block and reduce the impact of light rays, making them less sensitive to sunlight. However, people with light-colored eyes, such as blue or gray, often experience discomfort in bright sunlight, a condition known as photophobia.

7. Europeans with brown eyes aren't born with them.

Europeans, like people elsewhere, can have brown eyes, but what sets them apart is that most European babies are born with blue eyes. Brown eyes develop later as melanin production increases, leading to the term "baby blues," as explained in a LiveScience article.


All shades of brown eyes, from light to dark brown, are unique and attractive. They are all the result of amazing genetic selection. So embrace your brown eyes although they are not as rare as green, grey, or blue eyes.
