It's common for a sighted person to wonder what blind people see or for a blind person to wonder whether the experience is the same for others without sight. There is no single answer to the question, "What do blind people see?" because there are different degrees of blindness. Also, since it's the brain that "sees" information, it matters whether a person ever had sight.

What Blind People Actually See
Blind From Birth: A person who has never had sight doesn't see. Samuel, who was born blind, tells ThoughtCo that saying that a blind person sees black is incorrect because that person often has no other sensation of sight to compare against. "It's just nothingness," he says. For a sighted person, it can be helpful to think of it like this: Close one eye and use the open eye to focus on something. What does the closed eye see? Nothing. Another analogy is to compare a blind person's sight to what you see with your elbow. 

Went Totally Blind: People who have lost their sight have different experiences. Some describe seeing complete darkness, like being in a cave. Some people see sparks or experience vivid visual hallucinations that may take the form of recognizable shapes, random shapes, and colors, or flashes of light. The "visions" are a hallmark of Charles Bonnet syndrome (CBS). CBS may be lasting or transient in nature. It is not a mental illness and is not associated with brain damage.

In addition to total blindness, there is functional blindness. Definitions of functional blindness vary from one country to the next. In the United States, it refers to visual impairment where vision in the better eye with the best correction with glasses is worse than 20/200.1﻿ The World Health Organization defines blindness as presenting visual acuity worse than 3/60.2﻿ What functionally blind people see depends on the severity of blindness and the form of impairment.

Legally Blind: A person may be able to see large objects and people, but they are out of focus. A legally blind person may see colors or see in focus at a certain distance (e.g., be able to count fingers in front of the face). In other cases, color acuity may be lost or all vision is hazy. The experience is highly variable. Joey, who has 20/400 vision, tells ThoughtCo that he "constantly sees neon speckles that are always moving and changing colors." 

Light Perception: A person who still has light perception can't form clear images, but can tell when the lights are on or off.

Tunnel Vision: Vision may be relatively normal (or not), but only within a certain radius. A person with tunnel vision can't see objects except within a cone of less than 10 degrees.

[Introduction]

[Opening shot: A black screen with the title "What Do Blind People See?" appears, with dramatic music]

Narrator:  It's a question that has puzzled both sighted individuals and those without sight for centuries. What do blind people actually see? The answer, however, is not a simple one. Join us on this journey as we explore the various degrees of blindness and dive into the fascinating world of visual perception.

[Scene 1: Blind from Birth]

[Cut to the interview with Samuel, a blind individual, sitting in a comfortable room]

Samuel: When people ask me what I see, it's hard to explain because I've never had sight. It's not like seeing darkness or blackness; it's simply nothingness. There is no frame of reference, it's like trying to see with your elbow.

[Narrator's voice-over]

Narrator: For those born blind, the concept of sight is entirely foreign. Samuel compares it to closing one eye while the other focuses on something. What does the closed eye see? Nothing. It's void, a world of emptiness.

[Scene 2: Went Totally Blind]

[Cut to the series of interviews with individuals who have lost their sight.]

Narrator: But what about those who once had their sight and lost it? Their experiences can vary greatly. Some describe it as being surrounded by complete darkness, akin to being trapped in a pitch-black cave. Others may see sparks or experience vivid visual hallucinations.

[Cut to a close-up of visuals resembling those experienced by individuals with Charles Bonnet Syndrome]

Narrator: These "visions' are known as Charles Bonnet syndrome, which can manifest as recognizable shapes, random patterns, or flashes of light. It's important to note that CBS is not a mental illness and is not associated with brain damage.

[Scene 3: Functional Blindness]

[Cut to a visually impaired person using a cane to navigate the streets.]

Narrator: In addition to total blindness, there is a condition known as functional blindness. The severity of this impairment can vary, and it is often defined differently from one country to another.

[Cut to a close-up of a visually impaired person's eye]

Narrator: In the United States, functional blindness refers to a visual impairment where the best-corrected vision in the better eye is worse than 20/200. However, according to the World Health Organization, blindness is defined as presenting visual acuity worse than 3/60.

[Cut to a visually impaired person describing their experience.]

Narrator: For those who are functionally blind, what they see depends on the severity of their impairment and the specific form of visual limitation they experience.

[Scene 4: Legally Blind]

[Cut to an interview with Joey, a legally blind person, sitting in a living room.]

Joey: My vision is hazy, and things are often out of focus. I can see colors, but they're not as vibrant or clear as for someone with normal vision. It's like constantly seeing neon speckles that are always moving and changing colors.

[Narrator's voiceover]

Narrator: Joey, who is considered legally blind with 20/400 vision, explains the challenges he faces. While he can perceive large objects and people, his visual acuity is greatly diminished.

[Scene 5: Light Perception and Tunnel Vision]

[Cut to a visually impaired person observing a light turning on and off]

Narrator: For some individuals, even though they can't form clear images, they still have light perception. They can discern when lights are on or off, distinguishing between brightness and darkness.

[Cut to a person with tunnel vision navigating a crowded street]

Narrator: Others may have a condition called tunnel vision. Within a limited radius, their vision may be relatively normal. However, they cannot see objects beyond a small cone of less than 10 degrees.

[Conclusion]

[Narrator's voiceover]

Narrator: So, what do blind people see? The answer is complex and multifaceted. From the emptiness experienced by those born blind to the varying perceptions of individuals who have lost their sight, it's clear that there is no single answer. The world of visual perception is as diverse as the people who inhabit it.
