When a blind person sees nothing, it means that they are completely unable to see anything due to a physical or medical condition. Blindness can range from a partial lack of sight – where they can still make out some rudimentary shapes or have limited vision – to total blindness, where they cannot perceive any visual information at all.
In this latter case, they would see nothing when they look around the world, even though their other senses, such as hearing, touch, taste and smell, would still work.
The term “blindness” can refer to either total blindness, or to a range of other conditions that can lead to impaired vision. These include partial sightedness, where a person has some degree of sight, whether from birth or caused by an accident or illness; color blindness, where a person is unable to differentiate between certain colors; and low vision, where someone has some vision, but it is considerably worse than what is considered to be normal.
Living without sight can be very challenging, and many blind people rely on a range of techniques and technology to help them navigate the world and access services. These may include the use of a cane or guide dogs to help them navigate, braille to read books and other material, and tactile maps to help them understand their surroundings.
With the right support, however, it is possible for a blind person to lead an independent and fulfilling life.

Do blind people see black or nothing?
Blind people do not “see” black or nothing, as sighted people understand it. Blind people experience the world through their other senses, such as hearing, smell, taste, and touch. Through these senses, they can form an understanding of the environment and can form strong mental images of the things they encounter.
For example, a blind person might use the acoustic reflections from the environment to sense a wall or object. Through touch, they can feel the shape, size, and texture of things. Through smell and taste, they can recognize different scents and flavors.
This helps them to build up a picture of the world around them. It is not the same as sighted people seeing, but it does allow blind people to experience and interact with the world around them in their own unique way.
What Colour does a blind person see?
A blind person does not see any colours since they are not able to process light. When a person is blind, their vision is completely absent due to the lack of functional photoreceptors in their eyes.
Even those with partial sight, like me, do not experience any of the range of colours that we are used to seeing. Most of the time, a blind person will experience different shades of darkness and light, since they are able to process light but cannot make out shapes or images.
For some, they do not experience any shade at all, and can be completely in the dark.
Although blind people are unable to experience colour visually, many are able to become intimately familiar with colours and other details through other developed senses such as smell, touch, and sound.
They can also have a great understanding of their environment through memory and the careful use of tactile navigation which can help them to identify objects and people. Through these senses, a blind person can come to understand incredibly nuanced information about the world that would be lost to sighted people.
What do blind people see when they see nothing?
When a person is blind, they cannot see anything in the literal sense, since this is an impairment of the eyes which prevents them from perceiving visual input. However, blind people may still experience what is referred to as “dark vision,” which is a heightened ability to detect changes in light and motion.
For example, a blind person may be able to accurately detect the presence of a person walking in a room, even if they are not able to see them directly. Blind people may also be able to sense colors by getting a mental image of them.
This is often done through associating colors with other senses, such as texture, sound or texture. For example, someone who is blind may picture blue as a calming color since it symbolizes the sky and a sense of peace.
In addition, many blind people are able to utilize mental imagery and other cognitive processes to “see” the world. Therefore, when a blind person “sees” nothing, they may still be able to experience and process the world around them in a unique way.
What do blind people imagine?
Blind people can use their imagination just like anyone else! Just because someone can’t see objects or colors, doesn’t mean they don’t have a vivid imagination. Blind people may use other senses to help them imagine, such as their sense of smell, touch, and hearing.
They may also recall stories, music, or experiences from their life that help create strong mental images in their mind. For example, a blind person may be able to imagine a beach with white sand, clear blue water, and a warm sun shining down.
They can imagine the sound of waves crashing on the shore and the feeling of being engulfed in the warmth of the sun’s rays or the coolness of the water. Blind people may also be able to create images in their mind from reading a book or hearing a story.
Even without sight, blind people have become accomplished writers and poets, coming up with vivid and imaginative descriptions of the world around them.
What does nothing look like for a blind person?
For a blind person, “nothing” is an abstract concept. It is the absence of anything that can be sensed through sight or hearing. The concept of nothing is harder to comprehend for a blind person since these senses are not available for them to experience.
A blind person may think of nothing in terms of darkness and silence, since these are often associated with the absence of sight and sound. This mental image may also include sensory perceptions that are derived from other senses, such as texture, temperature, and smells.
For a blind person, nothing may feel like a feeling of emptiness and nothingness, as if they were floating in a sea of nothingness.
Additionally, the concept of nothing may also be associated with the idea of the unknown, where a blind person might not know what lies ahead or what’s around them. This can be a bit disconcerting and be difficult to grasp, as a blind person is often limited to their existing senses to experience the world.
In summary, “nothing” is an abstract concept that is hard to grasp for a blind person who is not able to rely on sight to experience their environment. However, the concept of nothing can be associated with darkness, silence, and the unknown, which can be mental images for a blind person to gain a better understanding of the concept.
Can you be blind and still see color?
Yes, it is possible to be blind and still see color. This phenomenon is referred to as “color vision in the blind”. While a person may not be able to physically see the colors, they have the ability to perceive, distinguish and recognize colors.
This is due to the different photoreceptors (cones and rods) in the eye interpreting and responding to light, even in people with no sight. People who experience color vision in the blind can usually distinguish between different colors, although the intensity and level of detail may be limited.
It is thought that this phenomenon is related to the retinal ganglion cell firing, which can even respond when there is no light, as observed in a study done by the University of California on blind people with color vision.
Can blind people see purple?
No, people who are completely blind cannot see purple, as the color is made up of light of different wavelengths, which someone with a complete vision impairment would not be able to perceive. People with partial vision impairment may be able to distinguish some shades of purple if they have some light perception.
People with color blindness may have difficulty in distinguishing between purple and other colors as well, depending on the type and degree of their impairment.
What is it called when you are blind but can still see?
It is called “low vision,” which is a term used to describe visual impairment that cannot be corrected with regular eyeglasses, contact lenses, medicine, or surgery. Low vision can range from mild to severe, and is often characterized by a decreased ability to see objects clearly, reduce image size, or detect color and contrast.
People with low vision may be able to see light and dark areas, but may not be able to recognize faces or objects. Low vision impacts individuals differently and is commonly caused by aging, injury, and inherited vision conditions such as glaucoma, macular degeneration, and cataracts.
What are the 4 types of blindness?
There are four primary types of blindness: congenital, traumatic, acquired and developmental.
Congenital blindness is an eye condition that is present at birth or very shortly afterwards. It is caused by abnormalities in the development of the eye or an inherited condition. The most common forms of congenital blindness are caused by cataracts, glaucoma, optic nerve disturbances, and corneal opacities.
Traumatic blindness is an eye injury that results in the loss of vision. This type of blindness can occur due to a traumatic injury such as a blow to the head or an accident. Unfortunately, it may not be possible to regain the vision once it is lost.
Acquired blindness is a form of vision loss that occurs later in life. This can be caused by age-related conditions, such as macular degeneration, glaucoma, or cataracts. Other causes of acquired blindness may include medical conditions like diabetes or diseases of the retina.
Developmental blindness is caused by neurological or developmental disorders. This can occur in infants and young children due to diseases such as cortical visual impairment (CVI) or optic nerve hypoplasia.
In some cases, developmental blindness can be reversed or improved with early intervention.
What level of blindness is a disability?
The level of blindness that qualifies as a disability would depend on the circumstance and definition used to define blindness. Generally, blindness is considered to be when someone has less than 20/200 vision in their better eye with the best corrective lenses.
In some rare cases, blindness can be defined as an inability to distinguish light from darkness.
A person who is legally blind may have some sight, but not enough to perform everyday activities – even with the use of corrective lenses. Legally blind people also tend to experience some difficulty with side vision and may find it difficult to identify certain colors or patterns.
Those who are totally blind have no sight and rely on other senses to gather information about their environment.
No matter the level of blindness, it can be a disabling condition that may interfere with daily tasks or the ability to work. People who qualify as legally or totally blind may be eligible for disability benefits and services.
How many types of blindness do we have?
There are different types of blindness, with causes ranging from birth or hereditary to acquired or temporary. The most common types of blindness include:
1. Total blindness: This is when someone has no light perception at all and can’t distinguish between light and dark.
2. Partially blind or low vision: This is when someone has some vision but can’t see clearly.
3. Color blindness: This is when someone can’t see all colors, or can only see some colors, such as blue and yellow.
4. Night blindness: This is when someone has difficulty seeing at night.
5. Deuteranomaly: This is a form of color blindness where someone can’t distinguish between green and red.
6. Presbyopia: This is a condition that occurs with aging, where someone can’t focus on nearby objects.
7. Glaucoma: This is a condition caused by increased pressure in the eye, which can lead to loss of sight.
8. Cataracts: This is a condition caused by clouding of the lens of the eye, which can cause vision loss.
Blindness can be permanent or temporary, depending on the cause. Treatment for blindness depends on the type and can involve medical treatment, surgical intervention, or lifestyle changes. In some cases, blindness may not be reversible, so it is important to seek medical attention if you are experiencing difficulty with your vision.
Can a blind person have visual hallucinations?
Yes, a blind person can experience visual hallucinations. Visual hallucinations are an experience that has been reported by people with no vision as well as by people with normal vision. Typically, this type of hallucination is thought of as a symptom of psychosis, but research suggests that a blind person can experience visual hallucinations without necessarily having a mental illness.
These types of hallucinations may be caused by temporary changes in the brain’s wiring or by an underlying neurological condition. Additionally, certain medications, such as anticonvulsants may produce visual hallucinations in blind people.
Visual hallucinations can also be caused by deprivation of stimuli such as light or intense physical activity. In any case, such episodes can be quite vivid and distressing, so if a blind person is experiencing them it is important that they seek medical attention.
Can blind people visualize things in their head?
Yes, blind people can visualize things in their head. Although not necessarily in the same manner or with the same detail as those with sight, studies have shown that blind people, especially those born blind, are able to create mental images or “visualizations” in their mind.
This typically involves engaging several senses, such as touch and sound, to build a mental picture of a person, place or item. For instance, by touching another person’s face, blind people can form a picture of what they look like, using their sense of touch.
Research has also suggested that this type of “mental imagery” is more common in blind people than it is among the general population.
