As of now, the commonly accepted theory is that eye colour has no real effect on vision quality. It's significant to note that while people with lighter eyes may have increased light sensitivity, those with dark eyes should still make it a point to wear sunglasses whenever they set foot outside.
Eye color doesn't significantly affect the sharpness of your vision, but it can affect visual comfort in certain situations. It all comes down to the density of the pigment melanin within your iris, which determines what colors of light are absorbed or reflected.
Of all eye colors, brown seems to be the only one that could be called “advantageous” from a survival perspective. While more research is needed, darker irises are linked to a number of health benefits, including these: Reduced risk of macular degeneration. Lower melanoma risk.
Macular Degeneration
This makes lighter eyes more sensitive to light. So, this is what makes people with blue eyes more likely to have age-related macular degeneration. Macular degeneration is caused when the light-sensitive cells in the eyes start to die, which can eventually result in blindness.
While lighter-colored eyes may be more sensitive to sunlight, they are not necessarily more sensitive to vision. In fact, blue eyes have better visual acuity than brown eyes. This means that blue-eyed people can see small details more clearly.
Blue Eyes are More Sensitive to Light
Melanin in the iris of the eye appears to help protect the back of the eye from damage caused by UV radiation and high-energy visible “blue” light from sunlight and artificial sources of these rays.
Light-eyed people (with blue or green eyes) have slightly better night vision because they have less pigment in the iris, which which leaves the iris more translucent and lets more light into the eye.
Disadvantages of Blue Eyes
Typically, people with blue eyes are likely to be more sensitive to light. With less pigment in the layers of the iris, they may be unable to block out the effects of bright fluorescent lights or sunlight. This condition of light sensitivity is called photophobia.
The allele genes come in the form of brown, blue, or green, with brown being dominant, followed by green, and blue being the least dominant or what is called recessive.
For most pigmentation genes, the allele for darker colors is stronger, or dominant. You only need to inherit one brown eye allele to see the color. The allele for lighter colors (like blue eyes!) is weaker, or recessive.
Brown eyes may have ranked as the least attractive, but they were 1.6 times more likely than blue eyes to be described as trustworthy.
And what would you think is the most attractive eye color? In a website poll of over 66,000 respondents, 20% said green was the most attractive, followed by hazel and light blue at 16%. Brown was far and away voted the least attractive (6%).
Of those four, green is the rarest. It shows up in about 9% of Americans but only 2% of the world's population. Hazel/amber is the next rarest of these. Blue is the second most common and brown tops the list with 45% of the U.S. population and possibly almost 80% worldwide.
Your children inherit their eye colors from you and your partner. It's a combination of mom and dad's eye colors – generally, the color is determined by this mix and whether the genes are dominant or recessive. Every child carries two copies of every gene – one comes from mom, and the other comes from dad.
Blond hair and blue eyes are one of the rarest combinations in the world (though red hair and blue eyes is even more rare), but such a combination is commonplace in Finland.
Although the traditional blue-eyed allele is rare in Asian populations, there are still a considerable number of people who have it.
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.
“Can two parents with blue eyes have a child with brown eyes?” Yes, blue-eyed parents can definitely have a child with brown eyes.
1. Angelina Jolie. It is a sacrilege to talk about beautiful eyes, and not talk about Jolie's blue eyes. The woman, apart from her award-winning roles, humanitarian efforts and plump lips, is known for her gorgeous blue eyes which are considered one of the sexiest in the world.
Charming, friendly, and attractive are just a few words to describe the blue eyed bunch. They are the type to help others and lend a helping hand. The great sense of observation and outgoing personality are just two added traits that come with having blue eyes.
Gray eyes may be called “blue” at first glance, but they tend to have flecks of gold and brown. And they may appear to “change color” from gray to blue to green depending on clothing, lighting, and mood (which may change the size of the pupil, compressing the colors of the iris).
"In Australians of European ancestry, the percentage of eye colours are 45 percent blue-grey, 30 percent green-hazel and 25 percent brown. If you're considering non-European ancestry it is the almost completely brown eye colour."
