The term “blind” is a very general one. If you are legally blind, wearing corrective glasses may help you see adequately. “Legally blind” is more of a legal phrase than a functional description.
In fact, the government of the United States uses the phrase lawfully blind to designate someone who is eligible for specific types of aid and services as a result of their visual impairment.
“Blind” and “legally blind” are both vague terms that encompass a wide range of experiences for those with visual impairments.
It’s natural for a sighted individual to ask what blind people see, and it’s typical for a blind person to wonder whether other individuals without sight have the same feelings.
There is no simple answer to the question “What do blind people see?” because there are various degrees of blindness also, since information is perceived by the brain, whether or not a person has ever had sight matters.
What do blind people see?
The answer to this question may depend on the person asking it.
For a person who has never had sight, the answer is probably going to be very different than for a person who was born blind but later gained some vision or for a person who slowly lost their vision over time.
There are different types of blindness, and each one affects the individual in a unique way. The three main types of blindness are:
A cataract is a clouding of the eye’s natural lens, which lies behind the iris and the pupil. Cataracts usually develop slowly and can eventually cause vision loss.
Symptoms of cataracts include blurry or fuzzy vision, trouble seeing at night, and halos around lights. While cataracts can occur at any age, they are most common in older adults.
Glaucoma is a group of eye diseases that damage the optic nerve, which is vital to vision.
The optic nerve carries information from your eye to your brain. If the optic nerve is damaged, vision loss can occur. Glaucoma is a leading cause of blindness for people over 60 years old.
Symptoms of glaucoma include gradual vision loss, usually in both eyes, and eye pain.
Macular degeneration is a disease that affects the macula, which is the center of the retina and responsible for sharp central vision. Macular degeneration can make it difficult to read, drive, or recognize faces.
There are two types of macular degeneration: dry and wet.
Dry macular degeneration is the most common type. Early dry macular degeneration may cause little or no vision loss.
However, as the disease progresses, people with dry macular degeneration may experience vision loss that cannot be corrected with glasses or contact lenses.

Does a blind person see black?
This is a common question and one that does not have a straightforward answer.
While it is true that blind people do not see color in the same way that sighted people do, they are still able to perceive light.
In fact, some blind people report seeing flashes of light or color when they are first exposed to bright light after being in complete darkness.
However, these perceptions are not consistent or reliable, and they do not give blind people the same level of color awareness as sighted people have.
While blind people may have some limited ability to perceive color, they do not see black. Instead, their brains interpret the lack of visual input as complete darkness.

Do blind people see in dreams?
There is no simple answer to this question. Some blind people report seeing images in their dreams, while others do not. It is difficult to know how often this occurs since dream recall is notoriously unreliable.
However, one study found that about 60% of blind participants reported seeing in dreams, compared to 96% of sighted participants.
This suggests that blind people are less likely to see in dreams than sighted people.
The reason for this difference is unclear, but it may be due to differences in the way that the visual cortex processes information.
Alternatively, it could be that blind people are simply less likely to remember their dreams. Either way, this question remains a mystery for now.

What does it look like to be blind?
Blindness is often thought of as a complete absence of sight, but this is not always the case.
Some people who are blind may have some residual vision, while others may only be able to perceive light and darkness. For many people who are blind, everyday tasks such as cooking, cleaning, and getting around can be challenging.
However, there are also many adaptive technologies that can help people with blindness lead independent lives.
Braille is a system of raised dots that can be used to read and write, and there are also talking computers and GPS devices that can provide assistance with navigation.
With the right support, people who are blind can live full and active lives.

Blind people see in a variety of ways. Some are able to see through the use of echolocation, while others use visual prosthetics.
Some blind people are able to form mental images, while others only see darkness. However, all blind people share one common experience: a complete lack of sight.
This means that they are unable to see objects, colors, or patterns. Even though they cannot see in the traditional sense, blind people are still able to perceive their surroundings in other ways.
For example, they may be able to sense movement or identify substances by touch.
They may also be able to recognize sounds and smells. Ultimately, blind people experience the world in ways that sighted people cannot imagine.
