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.
If you have a darker eye color, your eyes can often withstand high glare lights better than light colored eyes can. This is thanks to the greater amount of pigment and melanin in your iris. You could potentially be better at driving at night because your eyes allow for less light to reflect and cause glare.
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.
Darkness causes the molecules to regenerate in a process called “dark adaptation” in which the eye adjusts to see in the low lighting conditions.
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. Despite brown eyes ranking at the bottom of our perceived attraction scale, approximately 79% of the world's population sports melanin-rich brown eyes.
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.
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.
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.
While blue eyes used to be the least common colour and were seen as a rarity, 48% of the British population now have blue eyes. This is followed by green eyes at 30%, with a mere 22% of the British population having brown eyes.
Blue is the most attractive or beautiful eye colour, but only for some people, research finds. Blue-eyed males are particularly attracted to blue-eyed females, the researchers found. However, women showed no preference for blue or brown-eyed men and brown-eyed men showed no preference either.
Hazel eyes have also been voted as one of the most attractive eye colours and can, therefore, be argued to have the best of both worlds, health and beauty. Green eyes are incredibly rare, which may be the reason as to why some believe this to be the most attractive eye colour. Grey eyes are also a rare 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.
Keep one eye fully shut, and use the other for finding that item in the backpack with the flashlight on. Now, after you turn off the flashlight, open the closed eye, and close the open one. You will be able to see much better in the dark with the previously closed eye that was not exposed to light.
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.
Permanent changes to eye color can be achieved through iris implant surgery, corneal pigmentation, and laser eye color change. Iris Implant Surgery is a procedure that inserts a prosthetic iris into the eye. It was originally developed to treat iris defects such as albinism and aniridia.
They Are Less Prone to Certain Eye Diseases
The sun can cause severe eye damage and result in eye diseases like cataracts and macular degeneration. But because brown eyes have more melanin, it's safe to say that if you have brown eyes, you are less likely to get these types of eye diseases.
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.
Can two parents with blue eyes have a child with brown eyes? Yes, blue-eyed parents can definitely have a child with brown eyes. Or green or hazel eyes for that matter. If you stayed awake during high school biology, you might find this answer surprising.
In fact, in Ireland and Scotland, more than three-fourths of the population has blue or green eyes – 86 percent! Many factors go into having green eyes.
The colour is a result of a gene mutation which switches off the supply of brown eye melanin. The study mapped eye colour across the UK and Ireland and discovered the Scots and Irish were more likely to have blue eyes than people in other parts of the UK, especially the south.
It's All About Structure. The structure of the eye orbits, otherwise known as the bones around your eye, are directly linked to the attractiveness of your eyes. An orbiture with a bigger height and width is seen as more attractive than a smaller or thinner one.
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.
Yes, natural purple eyes are possible. There are many different shades of blues and greys out there and many in-between colors. Although very rare, some people's natural pigmentation can even be violet or purple in color.
The rarest skin color in the world is believed to be the white from albinism, a genetic mutation that causes a lack of melanin production in the human body. Albinism affects 1 in every 3,000 to 20,000 people.
Possible Causes
Glaucoma medications that work by constricting the pupil. Cataracts. Retinitis pigmentosa. Vitamin A deficiency, especially in individuals who have undergone intestinal bypass surgery.
