What Do Blind People's Eyes Look Like? Often Like Anyone's

Many blind people's eyes look like anyone else's. Often the problem is in the retina, the optic nerve or the brain, parts you can't see when you look at someone's face. Some blind people's eyes do look different: a pupil that looks white or cloudy, eyes that move on their own, eyes that point in different directions, a smaller eye, or an artificial eye.

Below: why so many look ordinary, what each visible difference is, whether blind people move their eyes, blink and cry, and what organizations of blind people say about talking with them. Pages were checked on October 30, 2026. This page describes how eyes look. It can't tell you why one person's eyes look the way they do, and it isn't medical advice.

Key points

• Ordinary-looking eyes are common. Sight depends on the retina, the optic nerve and the brain, all behind the parts you see (NEI).
• A white or cloudy look can come from a cloudy lens, called a cataract, or a cloudy cornea (NEI, NHS).
• Eyes that move on their own have nystagmus. Eyes that point in different directions have strabismus, also called a squint (AAO, NHS).
• Blind people move their eyes and blink. A 2025 study recorded both in people blind from birth (Hebrew University of Jerusalem).
• Talk to the person, not to a companion. That is one of the courtesy rules of the National Federation of the Blind (NFB).

Blind people's eyes at a glance

Each row is explained, with its links, in the sections below.

Why many blind people's eyes look ordinary

To see, the eye passes light through several parts. The NEI describes them in order. Light first goes through the cornea, "the clear front layer of the eye." Some of it enters through an opening called the pupil. The iris, "the colored part of the eye," controls how much light gets in. Next, light passes through the lens, a clear inner part of the eye that helps focus it on the retina. The retina is a layer of tissue at the back of the eye that turns light into electrical signals. The optic nerve carries those signals to the brain. "Then the brain turns the signals into the images you see" (NEI).

When you look at someone's eyes, you see the front: the white of the eye, the iris and the pupil. Many causes of blindness sit further back:

• The retina. Retinitis pigmentosa affects the retina, "the light-sensitive layer of tissue in the back of the eye" (NEI). Age-related macular degeneration damages the macula, a part of the retina that controls sharp, straight-ahead vision (NEI).
• The optic nerve. Glaucoma damages "a nerve in the back of your eye called the optic nerve" (NEI).
• The brain. In cerebral visual impairment, a child's vision problems are caused by the brain and "can't be explained by a problem with their eyes" (NEI). We explain it in cortical visual impairment.

In all three cases, the parts that changed are out of view. The front of the eye can look the same as before. That's why a person can be blind and still have eyes that look like anyone else's.

"Blind" also covers a wide range. Many people who are called blind, or who are legally blind, still see something: light, shapes or colors. See what is legally blind for the definition and what do blind people see for what people describe.

Why some blind people's eyes look white or cloudy

A cloudy lens: cataracts. The NEI defines a cataract as "a cloudy area in the lens of your eye" (NEI). Light reaches the lens right after it passes through the pupil (NEI). The NHS lists one or both eyes "looking white or cloudy" among the main signs of cataracts in children (NHS). Cataracts are one of the most common reasons people lose sight. The World Health Organization names refractive errors and cataracts as the leading causes of vision impairment and blindness worldwide (WHO).

A cloudy cornea. The cornea is "the clear, outer part of the front of the eye" (NHS). Because it is the very front of the eye, a change there sits in plain view. The NEI says deeper scratches or other injuries can scar the cornea and cause vision problems (NEI). Some conditions make the cornea itself cloudy. The NHS gives Fuchs' dystrophy, an inherited condition, as one example (NHS).

A cloudy look doesn't tell you how much a person sees. With a cataract, the AAO says, things look blurry, hazy or less colorful (AAO).

Why some blind people's eyes move: nystagmus

Some blind people's eyes move all the time, even when they are trying to hold them still. This is nystagmus. The American Academy of Ophthalmology describes it as a condition where the eyes move rapidly and uncontrollably. They can move side to side, up and down, or in a circle, and the movement usually happens in both eyes (AAO). The RNIB, a UK sight loss charity, says the constant movement is "sometimes described as 'wobble'" (RNIB).

Nystagmus can come with sight loss, but it doesn't have to. The RNIB says nystagmus that starts in infancy can come with another eye condition, and the more that condition affects a child's sight, the stronger the nystagmus tends to be (RNIB). It also says many children with nystagmus have no problem with their eyes, and that most people with nystagmus have some useful vision.

Two more things people notice:

• A turned or tilted head. The eyes may move slowest and most steadily when the person looks in one direction, which the RNIB calls the null zone. A child may tilt their head or look at things sideways to find it (RNIB).
• The world doesn't look shaky to them. Children with nystagmus usually don't see things as shaking, says the AAO. They may see things as blurry (AAO).

Eyes that point in different directions: strabismus

In strabismus, the eyes are not lined up and they "point in different directions." One eye may look straight ahead while the other turns in, out, up or down (AAO). The NHS calls it a squint. The NHS says it may happen all the time or come and go (NHS).

Six muscles move each eye, and "the brain controls these muscles," the AAO explains (AAO). Strabismus is common in people who see, too, so a turned eye on its own doesn't tell you whether someone is blind. The NHS says a squint is particularly common in young children (NHS).

A smaller eye or an artificial eye

Microphthalmia. Some people are born with one or both eyes smaller than usual. The NEI calls this microphthalmia, and being born without one or both eyes anophthalmia. Both are rare and can cause vision loss or blindness. People with them may also have small eye sockets, which can change the shape of the face (NEI).

Artificial eyes. Some people wear an artificial eye, also called an ocular prosthesis. That includes people born without an eye (NEI) and people who had an eye removed. At Moorfields Eye Hospital in London, each one is made of acrylic, moulded to the person's eye socket and hand painted. The hospital says this gives "a near perfect colour match to your natural eye" (Moorfields).

Artificial eyes can move. When an eye is removed, Moorfields explains, it is replaced with an implant in the shape of a ball, and some of the eye muscles are stitched to it. That way the muscles can move the implant, and the artificial eye fitted on top "should move in a similar way to your normal eye" (Moorfields).

Closed eyes and dark glasses

Some blind people keep their eyes closed or wear dark glasses, indoors as well as outdoors. The reasons range from light sensitivity to protection to personal choice, and not every blind person does it. We cover them in why blind people wear sunglasses.

Can blind people move their eyes, blink and cry?

Moving the eyes. Yes. Eye movement comes from muscles attached to the surface of the eyeball (Moorfields), controlled by the brain (AAO), not from the retina. A 2025 study from the Hebrew University of Jerusalem, published in the journal Brain Research, recorded eye movements in people who were blind from birth. It found quick eye movements, called saccades, and blinks in both blind and sighted participants. The authors point to "the presence of blinks and saccadic muscular movements" in the congenitally blind (Hebrew University of Jerusalem).

Blinking. Yes. In the same study, blink rate kept its usual profile in blind participants. Some details did differ, such as how long a blink lasted and how often and how far the eyes moved. Those differences looked like the ones in sighted people with their eyes closed (Hebrew University of Jerusalem).

Crying. Yes. Tears come from the lacrimal (tear) glands (Cleveland Clinic), which keep making tears to keep the eyes moist (University of Miami). We answer this one in more detail in how blind people do everyday things.

Talking with a blind person about their eyes

The National Federation of the Blind (NFB), an organization of blind people in the United States, publishes courtesy rules for people who meet a blind person. A few speak to the questions in this article (NFB):

• Talk to the person. "Please talk to me rather than a companion," and in your normal voice.
• Say "see" and "look." "It's ok to still use words such as see and look." The same rule adds: "I may not be able to make direct eye contact."
• Some sight is still blindness. A person may see a little and still use a cane. The NFB notes that people sometimes think such a person is faking.
• Ordinary is the point. "Blind people are ordinary."

The NFB Seniors Division's version of the rules addresses curiosity directly: "I'll discuss blindness with you if you're curious." It goes on to say you can talk about anything else, too (NFB Seniors Division). Neither list has a rule about questions on someone's eyes in particular.

Where Braillito fits

Braillito, our app, teaches braille. It teaches the braille cells in lessons with exercises you play, with lives, levels and a daily streak: 59 lessons in 8 worlds in English. It also has a translator, a dictionary and a cell builder. The English lessons are uncontracted braille (grade 1); they don't teach contracted braille or transcription, and Braillito isn't a braille transcriber.

How someone's eyes look doesn't tell you how they read; for reading by touch there is braille, and braille is learned (how blind people read). The translator on braillito.com shows how a word or short phrase looks in UEB, but it only applies the rules a program can apply, so it doesn't replace a transcriber. Without paying, the braille translator works in any browser.

Braillito is a subscription with no free version; depending on the plan, it starts with a free trial or a discounted first period, if it's your first subscription (is Braillito free?). Get Braillito.

Frequently asked questions

What do blind people's eyes look like?

Often like anyone else's. Many causes of blindness affect the retina, the optic nerve or the brain, which you can't see from the outside (NEI). Some blind people's eyes look different: cloudy, moving on their own, pointing different ways, smaller, or artificial.

Why are some blind people's eyes white or cloudy?

Usually because a clear part of the eye has turned cloudy. A cataract is a cloudy area in the lens, the clear part of the eye that helps to focus light (NEI), and the NHS lists eyes "looking white or cloudy" as a sign of cataracts in children (NHS). The cornea, the clear front of the eye, can also scar or turn cloudy (NEI, NHS).

Why do some blind people's eyes move?

Some blind people have nystagmus, a condition where the eyes move rapidly and uncontrollably, side to side, up and down or in a circle (AAO). It can come with an eye condition that affects sight, but most people with nystagmus have some useful vision (RNIB).
