COFFEEPERDAY.COM - Color blindness can affect people differently. There are three main types of color blindness that show different views of color, including red-green color blindness, blue-yellow color blindness, and total color blindness.

Each of these types of color blindness is caused by the inability of the red, green, or blue cones to process light in the retina.

If one or more of these cones doesn't respond, we experience color blindness. Because color blindness comes in many forms and is often misunderstood by those with normal color vision, there are many facts about color blindness that you may not have known about.

Keep up with this list to become an expert on the unique characteristics associated with color blindness.

11 Facts About Color Blindness You Should Know!

1. Not Easy to Recognize

One might think a lack of color vision would be easy to spot, but it can be very difficult.

Those with color blindness often do so from birth, meaning they may not know the difference.

In the early years, color blindness can also be mistaken for a learning disability similar to dyslexia.

2. Being picky is normal

Lack of color vision can make some foods look unattractive, creating picky eating habits. For example, peanut butter may have a green color. Color vision deficiencies can also make it difficult to determine whether certain foods are cooked or completely cooked.

Bananas and tomatoes can taste very different when ripe - although, without the ability to discern their colors, it is almost impossible to tell if they are ready to eat.

Likewise, one bad experience with undercooked meat can inspire you to stay away from it for the rest of your life.

Color blindness can make it difficult to determine whether meat is cooked or not, putting cooking efforts at risk.

3. Rare True Color Blindness

Those who are color blind are usually not completely color blind. Black and white color blindness is the rarest form of this condition.

Color vision deficiencies that limit or eliminate certain colors and shades are the more commonly expressed type of color blindness.

4. Not just heredity

Many people believe color blindness is exclusively a hereditary condition. This is by far the most common way to develop color blindness, but it is not the only way.

Color blindness can be transmitted through eye diseases, aging, and also damage to the eyes.

5. Having limitations in a career

Some careers in the United States, as well as overseas, have restrictions on hiring people with color vision deficiencies. For example, pilots, law enforcement officers, and military personnel should not have color vision deficiency. Other occupations such as electricians, engineers, and doctors can have some limitations because these job functions require the ability to see differences in colors and patterns.

6. One Eye Can See Color

In some cases, people who are color blind can still see one eye in full. This condition is called a one-sided compromise.

One-sided compromise is a very rare condition that allows you to see with normal color vision in one eye and a lack of color vision in the other.

7. Women are Bearers

Color blindness is more common in males than females due to its X-related nature. This means that a color blind mutation must be on the X chromosome.

Since women have two X chromosomes, mutations must occur in both, whereas mutations can only occur on one X chromosome in men.

Although deficiencies are more common in men, women are the more common carriers of the gene, making it possible to pass the gene on to boys.

8. All Babies Are Born Color Blind

At birth, all babies are born color blind and can only see in black and white. Color vision usually develops between the four months and six months mark of a baby's life.

9. Ishihara Color Blindness Test

The Ishihara color blindness test is one of the most common forms of diagnosis of color blindness.

This test uses a palette of colorful circles with one color making a number in the center.

During testing, one has to determine what numbers are on the pallet. This test was actually used exclusively by the Japanese Army before it became a more universally recognized tool.

10. Color Blind Test Can Be Done Online

If you are unable to visit an eye doctor, there are many tests available online to determine if you have a color vision deficiency, as well as what type of deficiency you have.

11. There is no cure

Currently, there is no cure for color blindness. However, there are ways to combat color blindness. Color-correcting sunglasses, regular glasses, and contact lenses can improve color vision for those who are deficient.

These glasses and lenses use light filtering to increase brightness and color depth, making them easier to see and distinguish.

Color blindness is a unique condition that can come in many forms. While we don't yet know a cure for color blindness, we do know of many trends and ways that color blindness can affect a person's life, such as the ability to drive, misdiagnosis of learning disabilities, and picky eating.

There are many facts that you may not know about color blindness unless you experience the deficiency yourself.
