The World through Their Eyes: What Does a Blind Person See?
Have you ever wondered what the world looks like to a person who is blind? Is it pitch black? Or is it something different altogether? The truth is that blindness is not the same for every person, and how they experience the world can vary greatly depending on the cause of their vision loss.
What does “blindness” actually mean?
To start with, it’s important to understand that “blindness” is a broad term that covers a wide range of vision loss. Some individuals who are classified as “legally blind” may still have some remaining vision, while others may have no vision whatsoever. This can be caused by a variety of factors, including injury, disease, or even genetics.
The different types of blindness
To get a better understanding of what someone with blindness may experience, it’s important to know the different types of vision loss. The three main categories are:
1. Total blindness
As the name suggests, individuals who are totally blind have no vision at all. This can either be from birth or caused by an injury or condition that results in complete loss of sight. For these individuals, the world appears completely dark, with no light or shapes visible.
2. Legal blindness
Legally blind individuals have some remaining vision, but it is severely limited. In the United States, a person is considered legally blind if their visual acuity is 20/200 or worse in their better eye, or they have a visual field of less than 20 degrees. This means that they may be able to see some light and shapes, but their visual perception is severely limited.
3. Low vision
Low vision is a term used to describe individuals who have significant vision loss, but still have some usable vision. This can include individuals who have conditions such as glaucoma or cataracts, as well as those who have experienced an injury. People with low vision may still be able to read, watch TV, or recognize faces, but they require visual aids to do so.
What do blind people “see”?
As mentioned earlier, blindness is not a one-size-fits-all experience, and how someone perceives the world depends on the type and severity of their vision loss. Some individuals who are blind may see nothing at all, while others may experience:
1. Total darkness
For an individual who has always been blind, their world is simply pitch black. There is no light or color, and no visual information to process.
2. Light perception
Some people with vision loss may still be able to detect light. This means that they can see the difference between light and dark, or even notice when a light is turned on or off. However, they are unable to process any additional information beyond that.
3. Shape and shadow
Those with low vision may be able to perceive some shapes and shadows, but not enough to see a fully formed object. They may be able to navigate around familiar spaces, but they may struggle in new environments.
4. Limited vision
Individuals with legal blindness may still be able to make out some details, such as large objects or high-contrast colors. However, they are unable to see fine details, read small text, or see things at a distance.
The reality of living with blindness
For someone who has experienced vision loss, the world can be a challenging and complex place. Simple tasks such as navigating through a crowded room or cooking dinner can become daunting without the use of sight. However, it’s important to note that individuals with vision loss are just as capable and deserving of a fulfilling life as anyone else. With the help of visual aids such as guide dogs, canes, or magnifiers, blind individuals can lead full and meaningful lives.
The takeaway
Understanding the different types of vision loss and how they affect someone’s perception of the world is an important step towards creating a more inclusive society. For those with vision loss, it’s important to remember that there is support available and that they are not alone. With the right tools and resources, individuals with blindness can lead happy, fulfilling lives and contribute to society in meaningful ways.
