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.
Those with darker colored eyes experience less visual discomfort in bright, sunny conditions. Also, darker irises reflect less light within the eye, reducing susceptibility to glare and improving contrast discernment—so people with darker eyes may have better vision in high-glare situations, such as driving at night.
Did Elizabeth Taylor have violet eyes? These days, thanks to colored contact lenses, anyone can have violet-colored eyes . Taylor didn't come by her purple peepers that way; the first tinted contact lenses weren't commercially available until 1983. Taylor's eye color was the real deal.
Pink and pale red eyes are also incredibly unusual eye colours and occur in people who have albinism. Albinism is when there is an absence of melanin which causes tiny red blood vessels to appear visible. Out of all the unusual eye colours, pink and red are the rarest in the world.
Gray, green, and blue eyes.
Lighter-colored eyes may mean an increased risk for cancer. Because lighter eyes have less pigment to protect them from harmful ultraviolet rays, it's true that light-eyed people have a greater lifetime risk for melanoma of the uvea, the middle layer of the eye, than their dark-eyed peers.
The allele for brown eyes is the most dominant allele and is always dominant over the other two alleles and the allele for green eyes is always dominant over the allele for blue eyes, which is always recessive.
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.
"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."
There are plenty of blue-eyed Asians. This probably happens when the traditional blue-eyed allele comes into a family from a (possibly very distant) European ancestor. Blue eyes then resurface in a child generations later if they inherit the allele from both parents.
A recent survey conducted by CyberPulse, a division of Impulse Research Corporation in Los Angeles uncovered this colorful research. Intelligence was the number one trait associated with brown, the most common eye color in the U.S., by 34 percent of respondents.
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.
The vast majority of people in the world have brown eyes. The second most common color is blue, but people can also have green, gray, amber, or red eyes. Some people have eyes that are different colors than each other.
According to some studies, there is a slight difference in vision capabilities based on eye color. 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.
Likewise, two brown-eyed parents can have a child with blue eyes, although this is also uncommon.
Babies inherit multiple pairs of genes from each parent that play a role in appearance. These genes determine hair color as well as eye color and complexion. And although scientists have yet to determine how many genes ultimately determine the exact color of a child's hair, they do understand how the process works.
Genetically speaking, then, people with brown eyes could be either BB or Bb while people with blue eyes could only be bb. Example of a one-gene model for eye color. For two parents with brown eyes to have a blue-eyed child, both parents must genetically be Bb.
A couple of years ago, scientist determined that BLUE EYES was a MUTATION that occurred around 6,000 years ago and it stems from A BLACK MALE AFRICAN ORIGIN. They report several archeological proofs puts this event around the BLACK SEA AREA.
Europe has the widest variety of eye color, according to Custers, who adds those of European descent are the largest population of blue eyes. Europe was the epicenter of the blue-eye gene mutation. More than 80 percent of the inhabitants of Estonia and Scandinavian countries have blue eyes.
Blond hair has also developed in other populations, although it is usually not as common, and can be found among natives of the Solomon Islands, Vanuatu and Fiji, among the Berbers of North Africa, and among some Asians.
Aussie Eye Color and Eyeshine. Our breed standard allows eyes of any pigment color or combination of pigment colors. Aussie eyes have been seen that are golden, lemon yellow, amber, light brown, dark brown, green, orange, and blue. On very dark individuals they may even appear black.
The Australian Shepherd is one of a few dog breeds that commonly have two different colored eyes, called heterochromia. Aussies might have any combination of brown, blue, hazel, amber, or green eyes. Some Aussies even display more than one color within the same eye.
What is it about Aussies that causes them to have heterochromia? It all comes down to genetics. Those two different eye colors, which is also known as wall eye, is one trait of many in dogs that their mother and father canine can pass down. With two parents, a puppy's gene copies double.
Australian Shepherds are especially prone to hearing, eye, and vision problems, including Collie Eye Anomaly (which can be prevented through good breeding practices) and cataracts. Cataracts may occur at any stage of life and present themselves as a cloudiness in the eye.
