Conjunctivitis Home People often call conjunctivitis “pink eye” because it can cause the white of the eye to take on a pink or red color. Symptoms of pink eye can vary but typically include redness or swelling of the white of the eye.
Unusual eye colors
True pink, red, or violet eyes are due to albinism, a condition in which the body is unable to produce or distribute melanin. The pink color is the color of the retina showing through. Heterochromia is a condition in which the color of one iris is different or partially different from the other eye.
Pink eye is most often caused by a viral infection. It also can be caused by a bacterial infection, an allergic reaction or — in babies — an incompletely opened tear duct. Though pink eye can be irritating, it rarely affects your vision. Treatments can help ease the discomfort of pink eye.
Pink and pale red eyes are also incredibly unusual eye colours and occur in people who have albinism. Albinism is when there is an absence of melanin which causes tiny red blood vessels to appear visible. Out of all the unusual eye colours, pink and red are the rarest in the world.
Green Eyes
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.
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.
Aside from being well-known figures to many people across the world, all three of them also have an eye condition known as Heterochromia, or two different colored eyes. Heterochromia is fairly uncommon, occurring in less than 1 percent of the 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.
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 infection can also be spread to others through close contact, such as a handshake, hug, or kiss. Coughing and sneezing can also spread the infection. You're at increased risk for pink eye if you wear contact lenses, especially if they're extended-wear lenses.
What does pink eye look like? In an eye with pink eye, the white part looks light pink to reddish and your eyelids are puffy or droopy. You might see fluid (discharge) coming from the infected eye or crusting on your eyelashes and eyelids.
Viral pink eye is most often caused by a common virus called adenovirus, but other viruses can also cause pink eye. If you have viral pink eye, you may also have a cold or sore throat. Bacterial pink eye can be caused by many different types of bacteria.
Some people think that black eyes are one of the rarest eye colors. Have you ever seen someone with eyes that seem black as night? Although they appear black, they are really just a very, very dark brown, which is caused by an abundance of melanin.
While some people may appear to have irises that are black, they don't technically exist. People with black-colored eyes instead have very dark brown eyes that are almost indistinguishable from the pupil. In fact, brown eyes are even the most common eye color in newborn babies.
Blue eyes are rare, making up just 8-10% of the world's population. Blue eyes are caused by a relative lack of melanin in the iris. Just like your skin and hair, how much melanin you have determines your eye color. All eyes are technically brown because melanin itself is brown.
A curious adult from California asks: 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.
The myth stops here
And while we have the least amount when we enter the world for the first time, remember that babies may be born with eyes of blue, brown, hazel, green, or some other color. It's simply a myth that all of us — or most of us, for that matter — are blue-eyed at birth.
The whites of your eyes (called the sclera) turn yellow when you have a condition called jaundice. The whites of your eyes might turn yellow when your body has too much of a chemical called bilirubin, a yellow substance that forms when red blood cells break down. Normally, it's not a problem.
Grey eyes are one of the rarest eye colors. Less than 3% of the global population has grey eyes. They're most commonly found in people of Northern and Eastern European ancestry. Like all eye colors, they're a product of the amount of melanin in the iris.
However, contrary to what you might think, blue and green pigment do not exist in the human ocular fluid or iris. In fact, only a couple of pigments are involved in eye color: melanin (brown) and lipchrome (yellow).
People with albinism usually have eyes that are very light blue. Rarely, they have pink or red eyes. Without melanin, their irises are clear, which makes blood vessels inside the eye visible. The blood vessels give eyes their pink or red color.
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.
The pupil can change size with certain emotions, thus changing the iris color dispersion and the eye color. You've probably heard people say your eyes change color when you're angry, and that probably is true. Your eyes can also change color with age. They usually darken somewhat.
Blue sclera: If the sclera is thinner than normal, blood vessels may show through, giving your eyeballs a blue or gray hue. This may occur in people with certain health conditions.
