Many of us have a fondness for a particular shade when it comes to eye colour, whether it’s our own or that of our partner or loved ones – but did you know that there is a statistically preferable colour? Previous research has confirmed that people are more interested in lighter irises than darker ones and it seems that the stereotype of blue eyes being the most stunning does exist, as recent research has shown that the most scientifically attractive eye colour is blue. Just 9% of people actually have blue eyes, so what is it about this shade that people love so much and where do other eye colours rank in terms of beauty?

Blue eyes are the most striking

There’s been plenty of research over the years to decipher what colour most people prefer in a partner and blue has come out on top once again. Studies of lists of the hottest celebrities between 2013 and 2018 showed that the list was made up of 23.5% blue-eyed men and women. In fact, guys with blue eyes were three times more likely to wind up on the list while women with blue eyes were 2.2 times more likely to win a spot on the coveted list. Much-admired stars like Michael Fassbender and Alexander Skarsgård have blue eyes, who have previously been named the hottest men of all time.

Interestingly, while we may associate this colour with “baby blues”, the reality is that we don’t have the full amount of pigment in our eyes at birth. So, many children are born with blue eyes which gradually changes to a different colour as they grow up. Researchers suggest that because there’s no improvement to eyesight and visibility in people who have blue eyes, the evolutionary advantage is to attract a mate, making a plausible hypothesis for why we think blue eyes are the most beautiful of all the colours in the spectrum.

It’s thought that maybe the fact that blue eyes reflect light more easily and therefore shine more is the reason why people believe it to be a more attractive tone. Whatever the reason may be, it seems that it’s playing a part in evolution, since despite the UK being a predominantly brown-eyed nation, the number of people with blue eyes has increased. If you weren’t born with blue eyes but have always longed to have them, coloured contact lenses & contact lenses are a solution that will let you change your appearance on a whim and experience what it’s like to have blue eyes, even if just for a day! (It's a bonus if you're already wearing lenses; daily contact lenses or monthly contact lenses & contact lenses with astigmatism.

Unique hazel eyes

Next on the list of most attractive tones is hazel – just 5% of the world’s population has this unique shade, despite 13.25% of the list of hottest celebrities having hazel eyes. Research suggests that having hazel eyes makes you up to three times more likely to land on the hottest list for men and 2.3 more likely for women. Celebrities who have this eye colour include Emma Watson and Camilla Belle. Hazel-coloured eyes differ to others in the sense that this colour is described in many different ways, from hazelnut to a greenish-brown colour. It can be difficult for people with this eye colour to definitively know if they even have hazel eyes as the colour seems to change in different lighting and even depending on what the person is wearing.

Green eyes are a rare find

For many people, green eyes are the epitome of beauty and it could have something to with the rarity of this eye colour – just 2% of the population is blessed with green eyes.

The prevalence of green eyes varies a lot depending on where in the world you live. People in Northern and Central Europe are much more likely to have green eyes, particularly people in Scotland where it’s estimated that 29% of locals have green eyes and just 14% have brown eyes. Likewise, in Iceland, a whopping 89% of women and 87% of men have either blue or green eyes. Despite the bad reputation associated with “green-eyed monster”, it would seem nothing has prevented this uncommon colour from being seen as extraordinary by the general public.

Brown eyes lose the contest

At the opposite end of the spectrum, grey eyes are much more common, and this colour is considered to be less attractive than blue or hazel. Last on the list is brown eyes – although they are by far the most common eye colour, they’re the least likely to wind up on the list of most attractive people. 79% of the population has brown eyes, so chances are you’re surrounded by people in your life with this particular eye colour.

The amount of melanin pigments in the cells of the iris impact the differences in eye colour – in the iris, this is known as melanocytes. Someone with less melanin in the melanocytes will have a lighter eye colour, like blue or green, while a greater concentration of melanin will result in deep brown eyes. Interestingly, people with blue or green eyes don’t actually have any blue or green pigment in their eyes – the colour is exclusively down to the amount of melanin.

It’s more than colour that determines attractiveness

It’s not just colour that affects how attractive someone can be considered though – it’s also the distance between your eyes that is an indicator of attractiveness. Average eyes without any perceptible difference over wide or close-set eyes are, unsurprisingly, considered to be the most attractive but that’s not to say that people with wide-set or close-set eyes are never considered attractive – celebrities like Camilla Belle are widely considered to be attractive, despite having close-set eyes.

Whatever colour eyes you have, everyone’s eyes are unique and can never be replicated. But, if you wish you had a different eye colour to the one you were born with, coloured lenses are a great solution that can enable you to switch up your look quickly from day to day. Especially if you're used to wearing daily lenses from our most popular brands, Acuvue. Clariti, Air Optix, Biofinity, Biomedics, BioTrue, Dailies, ProClear, PureVision.
