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.
Blue eyes. This is the next most common eye color, encompassing about 10% of the population. 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 fact, the top layer of a blue iris doesn't contain any pigment at all. This lack of pigment is the reason that blue-eyed people may be more sensitive to bright light and have a greater need to wear sunglasses than their brown-eyed counterparts.
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.
More melanin also means better protection from the sun-- the pigment in your eyes literally protects your retina. Light eyes such as blue, green or grey are more sensitive in sunlight. Most people are sensitive to sudden light, such as walking out of a dark hallway on a sunny day.
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.
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.
The most common characteristic thought to be associated with blue-eyed individuals: exuding sweetness by (42 percent), with being sexy (21 percent) and kind (10 percent) rounding out the top three.
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.
The more pigment is produced, the darker the eye colour. However, over time the number of these pigment-making cells can start to dwindle, and the ones that are left also produce less pigment. People with green or blue eyes will notice the most fading, usually by their 50s.
Natural Age-Related Eye Color Changes
As they are exposed to light, melanin production increases, causing the color of their eyes to shift. However, eye color changes can also occur as a person ages. Those with lighter color eyes – especially Caucasians – may see their eyes lighten over time.
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.
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.
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.
Gold and hues with tints of red and yellow, like orange, copper, and warm, brownish tones are perfect for emphasizing your blue irises. The contrast between these pigments and the blueness of your eye will really make them pop! So, as you can deduce, warm shades brighten up blue eyes and make them dazzle and shine.
Results found that blue was the most attractive eye color in males, garnering 47 out of 173 total matches—or 27.17 percent.
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.
Approximately 8% to 10% of the global population have blue eyes. A 2002 study found that the prevalence of blue eye color among the white population in the United States to be 33.8% for those born from 1936 through 1951, compared with 57.4% for those born from 1899 through 1905.
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.
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.
“Can two parents with blue eyes have a child with brown eyes?” Yes, blue-eyed parents can definitely have a child with brown eyes.
Iceland, the northernmost country of the bunch, has the greatest percentage of people with blue eyes.
Scientists believe that it is possible to trace all blue-eyed people back to a common ancestor, who likely had a genetic mutation that reduced the amount of melanin in the iris. Most people with blue eyes are of European descent.
Buton people has unique bright blue eyes, a physical characteristic which for Indonesians only “bule” or Caucassions would have. This unique phenomenon has been passed from generation to generation by the Butonese.
