Different Colored Eyes Day 2020 - Important Date, History, Causes, Facts, Quotes & How to celebrate the Different Colored Eyes Day

Different Colored Eyes Day 2020

Different Colored Eyes Day is celebrated on July 12 of every year across the country. Different Colored Eyes Day 2020 aims to celebrate the people who have the most attractive and unique eye colors. Different Colored Eyes Day is to observed to raise awareness about the diversity of eye color conditions and its effects.    

People with multicolored or two eyes with different colors are due to the certain eye condition called Heterochromia. There are many things that can cause Heterochromia, some of them being nothing more than a genetic trait, others caused by illness or injury. It occurs not only in humans and also found in dogs, cats and horses. About eleven out of every 1000 people have this condition. 

What is the history of Different Colored Eyes Day?

In order to raise awareness and celebrate the special qualities of those with different colored eyes, Jeanne Quinn of B Able, Inc. created National Different Colored Eyes Day. Many can go through life with little or no impact, depending on the degree of Heterochromia. Still, some may encounter complications from a confusing disorder that has affected them throughout their lives. People with different colored eyes should rejoice their condition on this day, and educate everyone about it.

What is Heterochromia?

Eye Heterochromia is caused by variations in melanin concentration and distribution, the pigment that gives skin, hair and eyes colour. The term ‘heterochromia’ comes from ancient Greek where ‘heteros’ means different, and color means ‘chroma.’ The disease is also called iridis heterochromia, or iridium heterochromia.

There are three types of Heterochromia, based on the position of different colours:

  • Heterochromia complete - It is where one eye's iris is a totally different color than another eye's iris

  • Partial Heterochromia - That is where only a part of one eye's iris has a different color to the rest of the iris of the same eye. There may be partial Heterochromia of one or both eyes

  • Central Heterochromia - For this type of Heterochromia, the iris has a different color near the pupil's border compared to the color of the rest of the iris, with center-color spikes radiating from the pupil to the middle of the iris

Melanin concentration and distribution determine the color of the eye, specifically iris's colour. The affected eye may be either hyperpigmented or hypopigmented (hypochromic). Furthermore, melanin abundance suggests hyperplasia of the iris tissues, while a lack of melanin causes hypoplasia. Blue eyes are weak in melanin, while brown eyes are high in melanin.

What is the cause of Heterochromia?

Iris color can not stay constant in a person's entire life. The majority of human cases of Heterochromia are benign and arise without any underlying abnormality. An infant with benign Heterochromia can be born, or it can become noticeable in early childhood when the iris reaches its full amount of melanin. These types are termed Heterochromia congenital. Congenital Heterochromia is generally an inherited genetic trait. Benign Heterochromia may also occur during embryonic development as a result of a genetic mutation.

Mosaicism and chimerism are two syndromes that can cause different colored eyes. Mosaicism contains two or more cell populations within a single organism. Chimaerism occurs when two or more fertilized eggs fuse together to create a single individual.

Heterochromia is known as acquired Heterochromia which occurs at the later part of life. Causes of acquired heterochromia include 

  • Diabetes

  • Eye surgery

  • Glaucoma

  • Eye injury

  • Iris ectropion syndrome

  • Pigment dispersion syndrome

  • Posner-Schlossman syndrome

  • Swelling of the eye

  • Tumors of the iris

This Heterochromia does not cause any problems, most of the time. However, it can be a symptom of something else, in rare cases. But the acquired heterochromia people should consult with doctors before they get severe.

Heterochromia - Facts

  • More than 200,000 individuals currently have Heterochromia in the United States

  • There are other forms of Heterochromia common in dogs , cats, and horses

  • An ophthalmologist should be able to detect Heterochromia and investigate why it happened

  • Heterochromia diagnosis is about treating the underlying causes

  • Heterochromia is closely related to the production of melanin

  • Some genetic changes can cause Heterochromia

  • It is common in some animals but rare in humans. It affects under 200,000 people in the U.S.

  • Heterochromy happens even in cats! White and tuxedo cats are most vulnerable because they bear genes that prevent melanin from entering the iris during the development period

Different Colored Eyes 2020 - FAQs

1. What do two different colored eyes mean?

Heterochromia occurs when two distinct colored eyes are present. Heterochromia is caused by differences in melanin concentration and distribution, the pigment that gives skin, hair and eyes colour.

2. What is the cause of having one blue eye and one brown eye?

The condition is called heterochromia iridis, and the iris, the colored portion of retina, is affected. It does not cause any issues, most of the time. Often it's just a color quirk caused by genes inherited from parents, or by a problem that occurred when the eyes were formed.

3. What color is the rarest eye color?

Most people regard green as the world's rarest eye color, but many others find it far more remarkable to have amber. So it is fair to assume that green or amber is the world's rarest pigment.

4. What is the prettiest eye color?

According to a new study, the most desirable eye colors are those with green, followed by hazel, and light blue eyes.
