Blind people don’t see anything at all, so technically they don’t “see” black or white. However, they can still interpret the world through various senses and experiences. For example, they can be taught to distinguish between different levels of lightness or darkness (in other words, shades of black and white) by interpreting various sound frequencies.
They can also identify objects, such as a white paper, by feeling it’s texture. The possibility of appreciating different color shades through sensations and experiences suggests that an individual who is blind can still appreciate the idea of contrasting lightness and darkness, the concept of black and white.
Ultimately, it is important to note that although a person is blind and cannot physically see, the ability to interpret the world and distinguish between two different factions is still possible.

What do completely blind people see?
Completely blind people do not actually “see” anything in the way that most people would think of it. This is because vision is relying on eyes that are able to detect light and color, and a brain that understands how to process visual signals, something that totally blind people do not have.
However, this doesn’t mean that totally blind people cannot sense the world around them in other ways. Studies have shown that totally blind people can sense things such as movement and the direction of sound, and have been known to have an increased sensitivity to temperature, texture, and even taste.
They can also use mental images of their environment to create an understanding of what is going on around them, such as the size and shape of a room, or the position of furniture. Lastly, totally blind people may use specialized tools like canes or seeing eye dogs to aid in their navigation.
What do blind people see when they see nothing?
When a person who is blind is asked what they “see” when they are in a dark room or looking at something without any visual stimuli, they may say that they do not actually see anything. Instead, they may describe the experience as one of physical darkness and mental awareness.
In other words, a blind person can still take in information about their environment, even without the use of their eyes. The person may not be able to access visual information, but they can still use their other senses to gain insight into their environment.
They may be able to determine the shape of a room by the echoes produced by their footsteps, or the temperature of the room by the feeling of a draft. Additionally, they may gain insight through hearing, because they can pick up subtle noises that may tell them where objects are in their environment.
This is just one example of how blind people experience their environment and process information without their sight.
Do blind people dream if they have always been blind?
Yes, blind people dream if they have always been blind. According to the American Foundation for the Blind, all people, regardless of their level of sight, dream. Dreams in the blind are composed of their own memories, experiences, and emotions as well as other senses such as sound, smell, and touch.
Although people who are blind cannot see images in their dreams, they’re still able to experience them with other senses like touch. People who have been blind since birth, due to having no visual input, may find their dreams lacking of images but instead heavier with feelings and other sensory inputs.
Therefore, it is clear that all people, regardless of visual acuity, dream.
Are blind people’s eyes open or closed?
The answer to this question depends on the individual. All people, regardless of vision, are capable of keeping their eyes open or closed. People with diminished or no vision usually keep their eyes open when they are awake, since visual stimulation isn’t necessary for them to understand their environment.
This puts them in the same category as people with full vision who may open or close their eyes to focus more closely on an object or to rest. The only time a person with diminished vision would have their eyes closed is if they were asleep.
Why are blind people’s eyes white?
The eyes of people who are blind may look white because the pupils are not responding to light and the irises are usually contracted or non-existent due to the lack of incoming light being reached from the eyes.
When a person is blind, their pupils are unable to expand, so the light coming in is not as prominent, resulting in the whites of the eyes appearing whiter. This is especially noticeable in darker environments where there is no other source of light to reflect off the iris.
In addition, people who are blind often suffer from nystagmus, which is when the eyes rapidly move back and forth due to the blindness and lack of light, making the whites of the eyes appear brighter.
Are blind people 100% blind?
No, blind people are not 100% blind. While someone who has complete blindness cannot experience any vision, there are varying degrees of blindness that involve some level of vision. People who are legally blind may have some vision, but not enough to meet daily life and work needs.
People with reduced visual acuity may experience blurred vision, light sensitivity, or difficulty seeing objects far away. Some individuals who are considered blind may be able to distinguish shapes and sizes or perceive movement and light.
Blindness can be caused by different illnesses, including glaucoma, cataracts, retinitis pigmentosa, and diabetic retinopathy. Individuals who are born blind often have additional conditions, including deafness and learning disabilities.
Additionally, it is important to note that rapidly progressing blindness is known as legal blindness and is typically measured by acuity. Visual acuity is still measured in individuals who are totally blind in order to distinguish between different levels of blindness.
Therefore, blind people are not 100% blind.
Do blind people have high IQ?
Blind people can experience a wide range of IQs, just like sighted people. However, studies have found that the majority of blind people do not have particularly high IQs, with a mean IQ of roughly 94 among blind adults in comparison to a mean IQ of 98 among sighted adults.
Additionally, there is also evidence to suggest that blind people may actually have a decreased cognitive functioning, with some studies suggesting that IQ scores among blind participants are typically lower than those of sighted participants.
However, it is important to note that the IQ scores of blind individuals can vary greatly, just as with any other population, and there are some documented cases of blind people with extremely high IQs.
Additionally, there are a number of adaptive strategies that blind people can use to increase their cognitive performance, such as using haptics or auditory cues, which could potentially increase their IQ scores.
All in all, while blindness is not necessarily associated with higher IQs, it is possible for blind individuals to have very high IQs, or to increase their IQ scores through adaptive strategies.
Is there anything worse than being blind?
There are a variety of conditions out there that may be worse than being blind, depending on the severity and the individual’s situation. For example, an individual living with a degenerative condition like multiple sclerosis that is gradually losing their ability to control their movement or with severe chronic pain caused by an illness or injury may experience a greater hardship than someone who is blind.
Additionally, an individual living with a cognitive disability that drastically limits their communication or an individual living with a mental illness that severely limits their ability to function in society may find their disability to be more challenging than blindness.
Ultimately, each person has a unique experience and limitation when living with a disability. Therefore, it is difficult to make a definitive statement on which disability is worse than another.
Do you only see black and white if you are color blind?
No, if someone is color blind, they may not be able to distinguish certain colors from others but they typically don’t just see black and white. Color blindness is caused by a lack of certain cone cells in the eyes, which allow people to accept different colored light, or the inability of the cone cells to recognize various colors.
People with one type of color blindness may only have difficulty seeing certain colors, while people with another type of color blindness can only see shades of blues and greens, or even just shades of gray.
There is also a rare condition called total colorblindness in which people only see in black and white, but this is very rare.
Can you be 100% color blind?
Yes, it is possible to have complete color blindness, or no color vision at all. This condition is called total color blindness or monochromatic vision and it is caused by an absence or malfunction of certain cells in the retina, called cone cells, which are responsible for color vision.
People with this condition are unable to see any colors at all—all items and objects appear only in various shades of gray.
Total color blindness is rarely seen, with incidence figures estimated between 0. 00002% and 0. 01%, and is more common in males than females. While regular color blindness is passed down through families and is caused by a mutant gene, total color blindness can be caused by several different medical conditions, such as optic nerve damage, macular degeneration, hereditary diseases and severe retinal damage.
What does red look like to a colorblind person?
For those with red-green colorblindness, red looks similar to a muddy brown color. This is because the cones in the eye that detect red and the cones that detect green overlap and can’t distinguish the two colors.
This is usually the most common form of colorblindness, followed by blue-yellow colorblindness, in which red appears as more of a yellowish green. For those with total colorblindness, red would look like a shade of grey.
What are the 4 types of color blindness?
Color blindness, or color vision deficiency, is a medical condition where a person is unable to differentiate between colors. It affects approximately 1 in 12 men and 1 in 200 women. Four common types of color blindness include:
1. Protanomaly – People with protanomaly have difficulty distinguishing red from green and have a reduced sensitivity to red light.
2. Deuteranomaly – This form of color blindness blurs the vision of green, with red and green appearing to be similar.
3. Tritanomaly – Those with tritanomaly have difficulty distinguishing blue and yellow, with objects appear to be red, green, and yellow all appearing as shades of gray and yellow.
4. Monochromacy – In this rarest form of color blindness, people cannot detect any colors, only shades of gray.
No matter the type of color blindness, it can have a significant impact on daily life and the ability to perform certain jobs. Treatment for color blindness is generally not available, although in some cases color-tinted lenses or special filters can help contrast colors to make them more distinguished from one another.
Additionally, there are colorblind glasses that help people with this condition, and some schools also offer specialized classes for color-blind students.
Why does grey look green to me?
It can be perplexing if you look at a color and see a different hue than what others all agree on. In the case of grey, it can look green to some people due to a few possible reasons. One is that your eyes may just naturally be more sensitive to greens, and the other is that the lighting, the angle the color is viewed from, and external factors such as color temperature and contrast can all influence the way colors appear.
For example, if you are in a room with greenish fluorescent lights, it is possible that they could make the grey color appear slightly more green or have a green tint. In addition, the quality of the display device you’re viewing the color on matters too.
If it’s an old screen or a CRT, it may have a display color shift that can make colors appear differently than they should. So while it can be strange or unexpected, grey or other colors may look green due to external influences that effect the way you perceive color.
