Blindness is a life-altering condition that prevents people from being able to see. Someone who is blind cannot see because they either have no ability to see or their eyesight is so impaired that it cannot be corrected with glasses. It’s not just as simple as someone who can’t see, but also nuances like how much sight they have lost and what their working vision is.
No one knows that better than the 152 million people around the world who are legally blind. There are many misconceptions about what it means to be visually impaired. This article will give you a better understanding of what blind people see and explain the differences between varying levels of blindness.
What Do Blind People See: A Guide to Help You Understand
Blindness is a difficult concept to understand. The fact that someone cannot see because of some physical limitation seems almost incomprehensible.
However, the idea that people who cannot see do not experience the world in the same way as those who can is also difficult to grasp. What do blind people see? In general, they don’t see colors or images like sighted individuals do; however, they experience their surroundings in other ways.
A person who is blind may have limited visual acuity and be unable to discern faces from across a room; however, this does not mean that he or she sees nothing at all. And that’s what we intend to explore here: What do blind people see?
What is blindness?
Blindness is a medical condition in which a person cannot see. It is a physical impairment, not a visual impairment. While a visual impairment may coincide with blindness, the two terms are not synonymous. Blindness can result from a variety of circumstances, including diseases, accidents, and genetics.
Age-related macular degeneration, diabetic retinopathy, and retinitis pigmentosa are some examples of diseases that can cause blindness. Blindness may also occur as a result of an accident, or it may be an inherited condition. In these cases, it is caused by damage to the eyes or other visual organs.
Basics of vision for sighted people
Vision is the most common way that people experience the world around them and enables them to interact with their surroundings. It is a complex process that occurs in the brain as well as the eyes. Blindness can be caused by a wide variety of eye conditions, including partial or total blindness.
Blindness can be inherited, acquired during childhood from a degenerative condition like Retinitis Pigmentosa, or caused by an accident later in life. Blindness can also be caused by eye diseases like macular degeneration, glaucoma, diabetic retinopathy, or retinitis pigmentosa. Blindness can be either partial, in which the person can still see some things, or total, where they don’t see any light at all.
Partial vision loss is a common result of aging and is sometimes called “presbyopia.” Partial vision loss can also be caused by certain diseases, like diabetes, or be the result of an injury.
Vision loss can be partial or total, and it can differ across the visual field. Blindness is often defined as a visual acuity of 20/200 or worse (20/200 is the level of visual acuity where you can only make out what a person with normal vision could see if they were 200 feet away).
What do blind people see?
The answer to this question depends on the cause and type of blindness. Blind people who have acquired their blindness later in life, after their visual pathways have already been established, often retain some limited visual abilities. Blindness that is caused by diseases like macular degeneration or diabetic retinopathy, however, will likely result in complete blindness.
Blindness that is congenital, or the result of genetics, will also likely result in complete blindness. Blindness caused by trauma, however, may result in some residual vision, which can be a common source of hope for people coping with complete blindness. For people who are blind from birth, the visual pathways in their brains have been rewired to process other senses to compensate for the lost visual information. Blind people often use their other senses, such as touch and hearing, to gain information about their surroundings.
Seeing with hearing
Some blind people are able to “see” by listening closely to the sounds around them in order to construct a mental image of their surroundings. These people have an excellent auditory memory and can easily recall auditory information from the past.
They may be able to tell the difference between different types of birds singing, or they may be able to distinguish between different types of cars driving by. Blind people may also be able to create a mental image of their surroundings based on how long it takes for sounds to travel to their ears.
Telling color and contrast using touch and smell
Some blind people can tell the difference between different colors by the way they feel or smell. Others can tell the difference between one color and another by the amount of contrast. A person might be able to tell that a blue car and a green tree are nearby if they feel both objects and can tell which is closer.
Blind people who use these types of sensory substitution are able to tell what colors things are by feeling different textures of fabrics. Others can tell the difference between colors by smelling various odors. Blind people who use these types of sensory substitution to discern color may have trouble telling the difference between different shades of a single color, like the difference between light blue and navy blue.
What do blind people see? They see the world with their ears, their nose, and their touch. A blind person often creates a mental image from these senses and from the input that they receive from their other senses. For example, a blind person could smell a flower and know that it is blue because the blue flower has a different texture and smell than a red flower.
Blindness is a complex condition that affects people in different ways. Some blind people can see a little, some can see a lot, and some can’t see at all. It’s important to treat every person you meet with respect. You never know what they can see, or what they’ve been through.
