Generally speaking, patients with lighter color irises, such as blue or gray, experience more light sensitivity than someone with brown eyes. The density of pigment in light eyes is less than that of a darker colored iris. When light hits a dark-colored iris, the higher density in pigment blocks the light rays.
While blue eyes are more sensitive to light during the day, people with blue eyes tend to see better at night – unless there are bright lights. In that case, the lack of melanin makes them as sensitive to light at night as they are during the day.
People with lighter eye colors may be more prone to light sensitivity than people with darker eyes, because lighter eyes contain less pigment to protect the eyes from bright lighting. In most cases, photophobia can be addressed by simply wearing sunglasses, blue light computer glasses and staying out of harsh lighting.
Ultimately, from these studies you can conclude that there is no significant difference between the eye's ability to see or affect reaction time. The only conclusive difference between blue eyes and brown eyes is that blue eyes are more sensitive to light since their isn't much pigment to absorb the light rays.
Green irises (the rarest eye color) have less melanin than brown eyes but more than blue eyes, for instance. “Brown is on one end, blue on the other, and hazel and green are in between,” Dr. Patel says.
Only about 5 percent of the population worldwide has the hazel eye genetic mutation. After brown eyes, they have the most melanin. . The combination of having less melanin (as with green eyes) and a lot of melanin (like brown eyes) make this eye color unique.
Purple eyes are also commonly referred to as “violet eyes,” as they are typically a light shade. For most people, this striking eye color can only be achieved with the help of colored contacts. But the fact is that a small (albeit very small) percentage of people are indeed born with purple eyes.
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.
Historically, throughout the ages, blue eyes have been the most desirable. It is a recessive gene and that is why a baby's eyes are typically blue. Because of this, blue eyes are reflective of youth and fertility. Blue eyes also represent innocence and carefree.
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. Green eyes don't possess a lot of melanin, which creates a Rayleigh scattering effect: Light gets reflected and scattered by the eyes instead of absorbed by pigment.
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.
Generally speaking, patients with lighter color irises, such as blue or gray, experience more light sensitivity than someone with brown eyes. The density of pigment in light eyes is less than that of a darker colored iris. When light hits a dark-colored iris, the higher density in pigment blocks the light rays.
However, cones are most sensitive to one of three different colors (green, red or blue). Signals from the cones are sent to the brain which then translates these messages into the perception of color. Cones, however, work only in bright light. That's why you cannot see color very well in dark places.
Fact: Two blue-eyed parents can have a child with brown eyes, although it's very rare. Likewise, two brown-eyed parents can have a child with blue eyes, although this is also uncommon.
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.
Disadvantages of Blue Eyes
It does not indicate vision loss, but it can create some difficulty focusing or seeing clearly in bright lights. It may also cause pain around the eyes. Studies show that blue-eyed people may be more at risk for developing eye melanoma.
Eye Shape #1 - Almond Eyes
Almond eyes are considered the most ideal eye shape because you can pretty much pull off any eyeshadow look.
The Rarest Eye Shape
Almond, monolid, downturned, hooded—the list goes on. But the rarest one is up for debate. Beauty is subjective, and opinions can vary drastically. Some people in North America might consider the monolid shape rare, but this is a common sight in East Asia.
When broken down by gender, men ranked gray, blue, and green eyes as the most attractive, while women said they were most attracted to green, hazel, and gray eyes.
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.
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.
Did Elizabeth Taylor Really Have Purple Eyes? This is a popular myth. Elizabeth Taylor's eyes appeared purple in some photos due to lighting, makeup, and clothing. In reality, her eyes were blue, which can be seen in the vast majority of her photos.
Many babies will have light-colored eyes at first, but iris color continues to develop for months after birth. Some babies may be born with blue eyes, but others are born with brown or hazel eyes. In fact, blue eyes may be a little less common than you think.
While some people may appear to have irises that are black, they don't technically exist. People with black-colored eyes instead have very dark brown eyes that are almost indistinguishable from the pupil. In fact, brown eyes are even the most common eye color in newborn babies.
