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 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 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 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.
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.

Although brightness may be an issue for light-eyed people, it's not directly related to the quality of their eyes and eyesight. In general, science has not found evidence that people with darker eyes have inherently better vision than those with paler irises.
Brown eyes may have ranked as the least attractive, but they were 1.6 times more likely than blue eyes to be described as trustworthy.
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.
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.
Red-green and yellow-blue are the so-called "forbidden colors." Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they're supposed to be impossible to see simultaneously.
An additional disadvantage of green eyes may be light sensitivity. If you have green eyes, you have less pigment in the iris. Due to this, it may be harder to block out sunlight or bright fluorescent light. As a result, your eyes may feel more sensitive to light.
What is the rarest eye color? Green is the rarest eye color in the world, with only 2% of the world's population (and fewer than one out of ten Americans) sporting green peepers, according to the American Academy of Ophthalmology (AAO).
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.
In 1907, Charles and Gertrude Davenport developed a model for the genetics of eye color. They suggested that brown eye color is always dominant over blue eye color. This would mean that two blue-eyed parents would always produce blue-eyed children, never ones with brown eyes.
One of the study's main findings was that gray eyes are both the rarest and the statistically most attractive eye color, with hazel and green following closely behind. Conversely, brown eyes are the most common color yet the least attractive to the survey's respondents.
While hazel was found to be the most attractive eye color in females. When it came to the most attractive eye color in females, the results were very different. Hazel eyes topped the list as the most popular, with 65 out of 322 total matches—or 20.19 percent.
Disadvantages of Brown Eyes
Brown eyes seem to put people at a higher risk for developing cataracts. According to the American Academy of Ophthalmology, one Australian study showed that the risk of cataracts may be twice as high for people with brown eyes compared to people with different eye colors.
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.
Brown eyes are resilient.
Brown eyes are more resistant to problems because they have more melanin. It also helps to repair DNA damage and to keep the eyes moist. People with brown eyes are also less likely to develop certain types of eye diseases, such as age-related macular degeneration.
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.
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.
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.
Eagles are thought to have the best eyesight of all; their eyes are as many as eight times sharper than ours.
