👁️ What Do Blind People See? Let’s Get Real…
If you've ever sat quietly and asked yourself, "What does a blind person actually see?"—you're not alone. This question has popped into nearly everyone’s head at some point, especially if you're someone like me who works closely with eyes, vision, and patients struggling with different degrees of sight loss.
I’m an optometrist, and over the years, I’ve come to realize that this question is way deeper than it sounds. The answer? It’s not simple. It’s not “just darkness.” It’s not “blackness.” In fact, for many blind people—there’s no visual component at all.
Today, we’re going to explore this fascinating topic thoroughly. This isn’t just from medical books or articles. This is based on real conversations, human experience, and science simplified for anyone to understand.
So buckle in.
🧬 The Basics First: What Is “Seeing”?
Before we talk about what blind people don’t see, let’s break down what it means to see in the first place.
Vision is a brain process, not just something that happens in your eyes. Your eyes are simply light sensors. They collect light, color, movement — and send that data to your visual cortex, a section in the back of your brain.
So technically speaking:
You don’t see with your eyes.
You see with your brain.
This is super important. Because in many cases of blindness, the eyes may still be working partially, but the brain can’t interpret the signals anymore. That changes what people “see” dramatically.
🧑🍼 Category 1: People Born Blind (Congenital Blindness)
Let’s start with the most misunderstood group — people who were born without any vision at all.
Here’s the straight-up truth:
People born blind do not see black. They do not see darkness.
They see nothing. Literally nothing.
When we close our eyes, we might say, “It’s all black.” But that’s only because we’ve experienced vision before. A person born blind doesn’t even have the concept of what visual black is.
One person born blind put it beautifully:
"Asking me what I see is like asking you what you see out of your elbow. It’s not black — it’s just… nothing.”
They don’t have visual dreams. They don’t “see” in their minds. But their other senses? Oh boy. Many blind people develop a heightened sense of touch, sound, smell, and spatial awareness that most of us can’t even imagine.
Their brain’s visual cortex actually gets rewired to support these other senses. Isn’t that wild?
👵 Category 2: People Who Lost Their Vision Later in Life
Now, this is a very different group. People who had normal vision for part of their life — whether it was 5 years, 15 years, or 50 years — and then went blind due to illness, trauma, or degeneration.
They usually still "see" something. And this “something” depends on:
-
How long they had sight before
-
The cause of the blindness
-
How much of the visual pathway (retina, optic nerve, brain) is still intact
Let’s break down what they might see:
✅ 1. Visual Memories
They often retain mental images — like family faces, a favorite tree, or a TV show scene.
Sometimes, they can visualize entire locations just by hearing a description. Their memory fills in the rest.
✅ 2. Dreams with Visuals
Many people who go blind later in life continue to have visual dreams—some even decades after losing sight.
It’s because the brain is still wired for vision, and dreams access old memories.
✅ 3. Light, Shadow, or Color Patches
Depending on how much of the eye or optic nerve is damaged, they may see:
Especially in glaucoma or diabetic retinopathy, patients might still sense some degree of light perception.
✅ 4. Hallucinations (Charles Bonnet Syndrome)
This is super common but not talked about enough.
Charles Bonnet Syndrome is when blind or visually impaired people see vivid images, shapes, people, or patterns that aren’t real — like a dream while fully awake. These are not mental illness hallucinations, but rather the brain trying to make up for lost visual input.
🔍 What Determines What Blind People See?
There’s no one-size-fits-all experience. But a few key factors decide what someone "sees" while blind:
| Factor | How It Affects Vision Loss |
|---|
| Cause of blindness | Retinal vs. brain-based makes a big difference |
| Age when vision was lost | Earlier = less visual memory |
| Remaining light perception | Some blind people still detect brightness |
| Mental health | Hallucinations more common in isolation |
| Time since going blind | Visual memories fade over decades |
🤔 So… Is It Just Like Darkness?
Let me answer this clearly:
No. Blindness is not just “seeing black.”
That’s a common misconception because most of us try to imagine blindness by closing our eyes. But even then, you’re still aware of shadows, pressure, ambient light, maybe the glow of your phone through your eyelids.
But for many blind people, especially those born blind, that concept doesn’t exist at all.
“Imagine an area you can’t see. The space behind your head. You’re not seeing black there—you’re just not seeing anything. That’s blindness.”
— a powerful quote from a blind interviewee I once heard.
🗣️ Real Words from the Blind
Let me share some quotes I’ve found from interviews and patients over time:
🔸 “I see memories, but no new images.”
🔸 “It’s not black. It’s the absence of sight, like a hole in perception.”
🔸 “When I lost my vision, my dreams went from color to sound and emotion.”
🔸 “I still see flashing lights sometimes, like lightning with my eyes closed.”
🔸 “I don’t see anything, just like you don’t see anything with your tongue.”
These are honest, unfiltered expressions that tell you one thing clearly:
We should stop assuming blindness means darkness.
💡 How Can We Help the Visually Impaired?
As someone in the eye-care world, I believe part of our job isn’t just diagnosis and glasses — it’s also about understanding, educating, and respecting those with vision loss.
Here are ways we can truly help:
-
Stop treating blind people like they’re broken.
Many live completely independent, successful lives.
-
Understand their experience.
Ask respectfully. Many are open to sharing.
-
Support accessibility.
From tactile pavements to audio announcements, every small feature helps.
-
Don’t assume total blindness.
Some may still have partial sight or light perception.
-
Use inclusive language.
Avoid saying things like “See that?” if you're unsure — say “Notice” or “Hear” instead.
🧘 A Final Thought: What Does “Seeing” Truly Mean?
Vision isn’t just about eyes. It’s about perception. Emotion. Experience.
A blind person can feel a moment more deeply than someone with 20/20 vision.
They may not “see” the sunset, but they can hear the birds as the sun dips below the horizon, feel the cooling breeze, and sense the change in the world around them.
Maybe that’s the kind of vision we all need a bit more of.
✍️ Closing Words From Me
As an optometrist and a curious human, I’ve always believed that sight is more than biology — it’s deeply human. Blindness doesn’t mean emptiness. It simply means experiencing the world differently.
So the next time someone asks you, “What do blind people see?” — you’ll know there’s no single answer.
It depends on when, how, and why they lost their sight.
But above all, it reminds us to be more aware, more compassionate, and a bit more thoughtful with our eyes — and with our hearts.
