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.
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. 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.
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.
Iris Color
This makes lighter eyes more sensitive to light and 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.
Benefits of Having Blue Eyes
Because less melanin allows for more light to pass through the eye, those with blue eyes can often tolerate longer periods of lower light. Blue eyes appear to have a lower risk of developing cataracts than brown eyes.
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.
Determining the rarest eye color... not so straightforward
Green is the rarest eye color of the more common colors. Outside of a few exceptions, nearly everyone has eyes that are brown, blue, green or somewhere in between. Other colors like gray or hazel are less common.
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 is the second most common eye color globally, with an estimated 8 to 10 % of people having blue eyes. A majority of these people are of European descent, however, Black people can be born with blue eyes even though it's pretty rare.
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.
Interestingly, in contrast to brown eyes, blue eyes were not associated with intelligence as only 7 percent of respondents thought of blue-eyed people as intelligent. Twenty-nine percent of participants associated green eyes with sexiness, the top characteristic thought to be related to this color.
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.
Lighter-colored eyes have less pigment to protect against sun damage and UV radiation compared to darker-colored eyes. This means that people with green, hazel, or blue eyes are more sensitive to light and more susceptible to UV damage.
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.
The 1-800-Contacts survey did align with a lot of that research, though: When asked about what personality traits they associated with each eye color, blue eyes were considered "sexy" and associated with a love for "trying new things" while brown eyes were considered "trustworthy" and "kind."
As for what eyeshadow colors will make blue eyes pop, think warm shades like orange, brown, peach, and terracotta, along with shimmery champagne and rich berry.
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.
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.
The second-rarest eye color is hazel, a mixture of brown and green with golden flecks. About 18% of Americans have hazel eyes, compared with about 5% of the world's population.
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.
Another reliable way to tell them apart is by looking at the specks within the iris. Blue eyes often have yellow or gold flecks, while grey eyes typically have brown ones.
Iceland, the northernmost country of the bunch, has the greatest percentage of people with blue eyes.
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.
Both parents have to pass along the blue eye gene in order for their child to have blue eyes. That doesn't necessarily mean that the parents themselves have to have blue eyes; it's possible they carry the gene, but it is recessive. However, a blue-eyed child is almost certain if both parents have blue eyes.
