Is the Blind Person the Color of His Black and White Dream?

Medical Video: Describing Colors As A Blind Person

When you hear "color blindness", the first thing that comes to our mind is often: the color blind sufferers can only see the world in black and white, just like watching TV in the past. Did you know that this assumption is not entirely correct?

There are many things you can learn about color blindness and there will be many questions that come to your mind when faced with this condition. However, some of the same questions still appear frequently on various occasions. This article is a summary of all these questions and will help you to satisfy your curiosity more quickly.

Is that color blind?

Color blindness is a condition that results from the absence of special color-sensitive pigments in eye cone cells (color receptors), a layer of nerves behind the eye that is responsible for converting light into nerve signals that will be sent to the brain.

Actually, the term "color blindness" is not entirely true, because even if someone has difficulty seeing a number of colors, he can still see other colors. A more effective medical term as a representation of this condition is color vision deficiency, aka limited color vision.

So what did they see?

Dr. Jay Neitz, professor of ophthalmology at the University of Washington, described that color blind people are able to see the same as what normal people see, but in color quality that is opaque and murky.

An individual with normal vision has three layers of color receptors (trichromatic) that allow the delivery of color signals to be clearer and more accurate, but blind sufferers only have two layers of color receptors (dichromatic) due to chromosomal abnormalities which make them unable to see the whole color spectrum. They tend to find it difficult to see or distinguish red, green, blue, or mixed colors from the three colors. They may also find it difficult to read colorful texts, depending on the type font and the background color.

The most common form of color blindness is green / red color blindness, but that doesn't mean they don't know which color is red and which is green. Color blind people mix all colors that have basic elements red or green. For example, someone who is green / red blind will find it difficult to distinguish between blue and purple, because they cannot 'see' the red color of purple (purple is a mixture of blue and red).

What are the dreams of colorblind people?

All depends on when exactly they become color blind. Humans dream about what they know and feel familiar. Therefore, people who have color blindness after birth can still 'see' colors, according to the book "Color Blindness: Causes and Effects" (2002). Of course, the colors they see in dreams match the colors they see in the real world.

However, it is different from the case of total color blindness. People who suffer from total color blindness from birth can only see the world (and dream) in shades of black, white and gray, because they never know what colors look like, and therefore their brains do not have memory over color anything to make a dream colored.

Can color blindness be cured?

The answer is no.

Color blindness is owned by 300 million people worldwide, and more often affects men than women. However, to this day there is no known treatment that can cure color blindness.

Almost all color vision problems are genetic conditions and are present since birth, although it is very unlikely that color blindness can occur later in life due to various external factors, such as aging, disease, eye or optic nerve injury, or side effects of certain drugs.

Many modern studies are working on the possibility of injection of color genes to restore one's vision to its maximum capacity, but a number of these studies have not been able to find a bright spot.

Can color blindness be dealt with?

A person who is color blind cannot accept the same perception of nuances and color patterns, therefore it is almost impossible to change that state.

But, there are several lenses and other tools that claim to improve vision. Is it true?

Using a color correction lens means you will be required to buy two different color contact lenses. This will cause a shift in the color spectrum you feel; You might be able to see some other colors for one eye, but on the other hand you might feel the loss of other colors. A lens like this might help a little, but many people report that the benefits are not very effective.
