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.
If your eyes are wide horizontally, they are considered to be more attractive. This is true of men and women and all facial types. This width is known as the palpebral fissure length, and the longer it is, the more attractive your eyes become.
India, being land of diversities, has several unique features and beautiful attractions. The dusky complexioned stunning Indian women are famous in the world for their mysteriously gorgeous aura. Their long dark hair and beautiful eyes make them simply breathtaking.
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.
Of the less common eye colors, pink and red eyes are considered to be the most unique in the world, giving new meaning to the word “rare.” Only one in every 20,000 people have a form of albinism, according to the National Institutes of Health, and even fewer have red-tinted eyes.
Mantis shrimps (Stomatopoda)
Mantis shrimps probably have the most sophisticated vision in the animal kingdom. Their compound eyes move independently and they have 12 to 16 visual pigments compared to our three. They are the only animals known to be able to see circular polarised light.
Conversely, brown eyes are the most common color yet the least attractive to the survey's respondents. According to World Atlas, approximately 79% of the world's population has brown eyes, making it the most common eye color in the world.
Eagles are thought to have the best eyesight of all; their eyes are as many as eight times sharper than ours. We don't do too badly either. Our vision is four to seven times as sharp as those of cats and dogs and 100 times sharper than that of a mouse or fruit fly!
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.
Analysing the data by male and female, it's Indian women that top the tables of the most attractive, followed by Japanese and Swedish women.
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.
There's a little genetic tweak that makes the combination of red hair and blue eyes the rarest of them all. The same Nature study mentioned above found that another gene variant, HERC2, interacts with both the MC1R gene and the OCA2 gene—and it can shut off the redhead gene while expressing blue eyes and blonde hair.
As a group, the Aborigines have significantly better visual acuity than the Europeans. This was true for both monocular and binocular vision. Some Aborigines have acuities below the previous postulated threshold levels. Aborigines as a group also have the previous postulated threshold levels.
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.
Green, which is the least common eye color. Only 9% of people in the United States have green eyes. Hazel, a combination of brown and green. Hazel eyes may also have flecks or spots of green or brown.
From these data, it can be concluded that eye size is strongly related to facial attractiveness, but the relationship between them is not absolute. Not all faces with high attractiveness scores have large eyes, but small eyes with the appropriate eyebrow shape can also make face increasingly attractive.
Kind eyes simply mean you care. You care about yourself and you care for those you meet. Care doesn't mean you love or even like them. Care means you take a moment to perhaps think of the bigger picture in that you haven't walked in their shoes and you don't live their life.
According to the results, both men and women view the eyes as the most important facial feature. The other highly rated facial features included attractive hair and lips, while the nose was reported as one of the least important features.
The real answer: They were not purple at all, but a vibrant dark blue. Her eyes merely appeared to be purple when exposed to certain lighting, makeup, or clothing (and plenty of retouching of her images, we're sure!).
It seems that the best eyesight ever reported in a human was in an Aborigine man with 20/5 vision! To give you an idea of how clear and far he could see, his vision measurement compares to the natural sight of eagles. From 20 feet, he could perceive the fine details that most people can only see from 5 feet away!
Overall, it was found that several specific eye shape features correlate with attractiveness and perceived age. For instance, large visible height of the iris and large upward and lateral inclination of both eye axis and eyebrows correlated moderately to strongly with attractiveness (p < 0.05).
