Legally blind vision is when a person can only see at 20 feet what someone with normal vision can see at 200 feet. This means that it is difficult for someone with legally blind vision to make out details or colors in their surroundings and to identify objects and recognize faces.
Legally blind vision is a condition where a person’s sight is impaired to such an extent that it affects their daily life. It is a permanent impairment that cannot be corrected by medication, surgery, or glasses. Legally blind vision can be caused by a variety of conditions, including cataracts, glaucoma, age-related macular degeneration, and retinitis pigmentosa. Symptoms associated with legally blind vision include blurred or distorted vision, difficulty seeing at night, and a loss of peripheral vision. Many people are curious to know what number is considered legally blind vision. In this blog post, we will discuss the exact number associated with legally blind vision, the causes and symptoms of legally blind vision, and the effects it can have on a person’s daily life. We will also discuss the treatment options, coping strategies, and resources available for people with legally blind vision. Finally, we will discuss the impact of legally blind vision on quality of life and share stories from people with legally blind vision.
Causes of Legally Blind Vision
Legally blind vision is defined by a person having a visual acuity of 20/200 or worse, with the best possible correction. This can be caused by a variety of factors, which we will explore in further detail in the following sub-subheadings.
Common causes of legally blind vision
Legally blind vision is defined as having a visual acuity of 20/200 or worse in the better eye with best correction, or a visual field of 20 degrees or less. Common causes of legally blind vision include age-related macular degeneration, glaucoma, diabetic retinopathy, cataracts, corneal diseases, retinal diseases, optic nerve diseases, genetic disorders, and traumatic brain injury.
Age-related macular degeneration is the most common cause of legal blindness. It is a condition in which the macula, the center of the retina, deteriorates and causes a decrease in central vision. The risk of developing macular degeneration increases with age, and it is most common in those over the age of 65.
Glaucoma is another common cause of legal blindness. It is a condition in which the optic nerve is damaged due to increased pressure in the eye. Glaucoma is often asymptomatic, so it is important to have regular eye exams to check for the condition. It is most common in those over the age of 40.
Diabetic retinopathy is a complication of diabetes that affects the eyes. It is caused by damage to the blood vessels of the retina and can lead to vision loss. It is most common in those with diabetes, particularly those with poorly controlled diabetes.
Cataracts are a clouding of the lens in the eye that can cause vision loss. They are most common in those over the age of 60, and can be treated with surgery.
Corneal diseases are diseases of the outer layer of the eye that can cause vision loss. These include conditions such as keratoconus and corneal dystrophies.
Retinal diseases are diseases of the inner layer of the eye that can cause vision loss. These include conditions such as retinitis pigmentosa and age-related macular degeneration.
Optic nerve diseases are diseases of the nerve that carries light from the eye to the brain. These include conditions such as glaucoma and optic neuritis.
Genetic disorders can also cause vision loss. These include conditions such as retinitis pigmentosa and Leber’s congenital amaurosis.
Finally, traumatic brain injury can cause vision loss. This is usually due to damage to the brain that affects the visual centers of the brain, or to damage to the eyes themselves.
In conclusion, there are many common causes of legally blind vision, including age-related macular degeneration, glaucoma, diabetic retinopathy, cataracts, corneal diseases, retinal diseases, optic nerve diseases, genetic disorders, and traumatic brain injury. It is important to have regular eye exams to check for any of these conditions, as early detection and treatment can help to preserve vision.
Symptoms of Legally Blind Vision
Legally blind vision can vary in severity and the following are some of the most common symptoms associated with the condition.
Symptoms associated with legally blind vision
Legally blind vision is defined as having a visual acuity of 20/200 or less in the better eye with best possible correction, or a visual field of less than 20 degrees in the better eye. Symptoms associated with legally blind vision include difficulty seeing objects far away, difficulty driving, difficulty recognizing faces, difficulty reading, seeing objects in low light, and difficulty seeing objects in the peripheral vision. Other symptoms include a need for extra lighting when reading, double vision, and a need for larger print size when reading.
It is important to note that someone with legally blind vision may not be completely blind, as they may still have some vision. For example, they may be able to make out shapes, recognize colors, and even make out some details. However, in most cases, the vision is significantly impaired, making it difficult to perform everyday tasks.
If you suspect that you or someone you know may be legally blind, it is important to seek medical attention and get a proper diagnosis. This will ensure that the right treatments and accommodations can be put into place to help improve daily life.
The Numbers
To answer this question, it is important to understand the parameters of legally blind vision.
What is the exact number considered legally blind vision?
The exact number considered legally blind vision is 20/200 or worse with corrective lenses, or a visual field of 20 degrees or less. This is defined by the American Foundation for the Blind, and it affects an estimated two million Americans. Up to 25% of those affected may be completely blind.
When taking a vision test, an eye doctor will measure the sharpness and clarity of vision to determine the exact number. If the patient is able to improve their vision with glasses or contacts, they are not considered legally blind.
It’s important to note that having legally blind vision does not necessarily mean that the person is completely blind. There are many levels of visual impairment, and those who are considered legally blind may still have some sight.
If you think you or someone you know may have legally blind vision, it’s important to get a vision test from an eye doctor. Doing so can help you determine the exact number and get access to the resources you need.
Effects of Legally Blind Vision

Legally blind vision is defined as a person having a visual acuity no better than 20/200 with conventional correction. This can have a major impact on a person’s daily life and activities, as it affects their ability to navigate the world, perform daily tasks, and use visual aids. For example, those with legally blind vision may need to rely on non-visual aids like walking sticks, or other assistive devices, to help them move around safely. They may also need tactile or auditory cues to help them identify objects or people, and may be unable to read printed materials due to reduced visual acuity.
For those with legally blind vision, it is important to seek out services and programs that can help them cope with their vision loss and improve their quality of life. These can include low vision rehabilitation, adaptive technology, and emotional support. With the right help and support, those with legally blind vision can continue to lead fulfilling and independent lives.
