If someone cannot distinguish this letter with his prescribed glasses, he is considered blind within the meaning of the law. An estimated 1.1 million Americans are legally blind. Certain conditions, such as glaucoma, cataracts, diabetes, and macular degeneration, can affect your vision to the point where you can be diagnosed with the disease. Blind people are “legally blind,” but some people who can see with strong eyeglasses say they are legally blind without their glasses. This means that without glasses, they might not see well enough to see certain things, drive, etc. Visual acuity below 20/200 is considered blind under the law, but to truly fit the definition, the person must not be able to achieve 20/200 vision, even with prescription glasses. Many people who would be legally blind without glasses can function well in everyday life with proper glasses or contact lenses. What are the main causes of blindness? According to the National Eye Institute, there are four main causes of blindness in the United States. “Legally blind” is the definition of blindness used by the United States Social Security Administration (SSA) to determine whether a person is eligible for disability benefits, tax exemptions, and training for the visually impaired.

They have programs to help you cope with the physical and emotional effects of vision loss. Treatments for legal blindness vary depending on the cause and stage of the disease. Age-related eye conditions are usually prescription medications or eye procedures aimed at delaying or preventing vision from getting worse. The Iowa Department for the Blind also serves people who are functionally blind.

A person is functionally blind when they have to use so many alternative techniques to perform tasks that are normally performed with vision that their daily lifestyle is significantly altered. These alternative techniques could include reading a newspaper while listening to the phone or using Braille to read a book. According to the American Foundation for the Blind, legally blind is not the same as completely blind, which is used to describe the inability to see anything with both eyes. Most people who are legally blind have some eyesight. How do you define vision loss, poor vision and legal blindness? Eye trauma or injury and genetic diseases, such as Usher syndrome, can also lead to legal blindness. Normal visibility is 20/20. This means that you can clearly see an object from 20 feet away. If you are legally blind, your vision is 20/200 or less in your best eye or your field of vision is less than 20 degrees. That is, if an object is 200 feet away, you must stand 20 feet away from it to see it clearly. But a person with normal vision can stand at 200 feet and see this object perfectly. You may be surprised to learn that it is Uncle Sam, not the doctor, who determines whether you are legally blind.

You measure your eyesight by wearing glasses or contact lenses. Their vision could fall below 20/200 without them. If it improves when you put on your glasses or contact lenses, you are not considered blind under the law. The government uses the term “statutory blindness” to decide who can receive certain benefits, such as disability or vocational training. This is not the same as being completely blind. The reason some people use this term is because there are many different types of “blindness.” People mistakenly believe that all blind people see only darkness or literally nothing at all. In fact, blindness may involve seeing colors or light, or having greater visual acuity in some parts of their field of vision, while others are blurred or absent. Striem-Amit E, Gen M, Amedi A. “Visual acuity of congenital blind persons by visual sensory substitution for auditory. PLoS One. 2012;7(3):e33136. doi:10.1371/journal.pone.0033136 A common test for visual acuity is Snellen`s eye chart.

Someone who is legally blind could simply read the top row of the chart, a capital E, while wearing corrective lenses. The line under the capital E is the line for 20/100. There are also tests that can measure between 20/200 and 20/100. Someone who can`t see the line for 20/100 but sees somewhere between 20/100 and 20/200 would still meet the government`s standard of legal blindness, which is why they are listed as “20/200 or less.” An ophthalmologist will measure visual acuity and visual field to determine if a person is legally blind. When determining right blindness, the field of vision (the part of a person`s vision that allows them to see what is happening on their end) is also taken into account. A field of vision of 20 degrees or less is considered blind under the law. Ophthalmologists can help diagnose right blindness. A legally blind person with 20/200 vision (with the best corrective lenses) would have to be 20 feet away from an object to see it, and someone with 20/20 vision could see it from 200 feet away.

What is legal blindness? If you are completely blind, you cannot see any light or shape. Among people with eye diseases, only about 15% can see nothing at all. If you are legally blind, you can still see, but not so clearly. Most government agencies and health care institutions agree that legal blindness is defined as visual acuity (central vision) of 20/200 or worse in the best sighted eye or a field of vision (peripheral vision) limited to only 20 degrees. Visual acuity of 20/200 means that what the legally blind person can see at 20 feet, the average person can see clearly at 200 feet. When it comes to the field of vision, the average person can see 140 degrees without turning their head. We have all heard the term “legally blind,” but what does that really mean? How is it different from complete blindness and who is considered legally blind? To be legally blind, you must meet one of two criteria: visual acuity (visual acuity) and field of vision (the full range of what you can see without moving your eyes). Legal blindness occurs when a person has a central visual acuity (vision that allows a person to see right in front of them) of 20/200 or less in their best eye with correction. With a visual acuity of 20/200, a person can see at 20 feet what a person with a vision of 20/20 sees at 200 feet.

If you are legally blind, you are also eligible for certain government programs and benefits, including the pension for the blind and subsidies for public transportation.

People often ask about the difference between being blind and being “legally blind.” Because “blindness” can mean many different things, legal blindness is the threshold at which a person is considered visually impaired for legal purposes, such as for insurance purposes, to receive certain benefits, or to enroll in various programs. Someone who is legally blind has corrected vision of 20/200 in their best eyesight. You may feel legally blind if you can`t see beyond one foot in front of you without wearing glasses, but as long as your vision can be corrected 20/20 with a visual aid like glasses, you`re not considered legally blind. A number of conditions can lead to vision loss, poor vision, and blindness. About 80% of blind people have residual vision. It can be difficult to understand how a person with a particular eye condition can see some things while not seeing others.

While some people lose a lot of vision in a short time, others slowly lose vision. Many diseases that cause blindness begin to affect a certain part of vision and then progress to remove more vision.
