Apr 26, 2021 · 20/20 is a term to describe normal visual acuity. Visual acuity is how clearly you see at a specific distance. For example, when your eye doctor asks you to read letters off a chart during an eye exam, they are measuring your visual acuity. With a measurement of 20/20, the first number indicates the test distance.
A person whose best corrected vision is between 20/70 to 20/200 is often referred to as "visually impaired" or having "low vision." This person would not be legally blind but will likely have some difficulty with certain visual tasks.

The Americans with Disabilities Act (ADA), which was amended by the Americans with Disabilities Act Amendments Act of 2008 ("Amendments Act" or "ADAAA"), is a federal law that prohibits discrimination against qualified individuals with disabilities. Individuals with disabilities include those who have impairments that substantially limit a major life activity, have a record (or history) of a substantially limiting impairment, or are regarded as having a disability. Title I of the ADA covers employment by private employers with 15 or more employees as well as state and local government employers. Section 501 of the Rehabilitation Act provides similar protections related to federal employment. In addition, most states have their own laws prohibiting employment discrimination on the basis of disability. Some of these state laws may apply to smaller employers and may provide protections in addition to those available under the ADA. The U.S. Equal Employment Opportunity Commission (EEOC)...
Estimates vary as to the number of Americans who are blind and visually impaired. One reason for the different estimates is that different terminology is used to assess the number of individuals with some degree of vision problems. According to one estimate, approximately 6.6 million people in the United States are blind or visually impaired. Another estimate concluded that there are 10 million blind or visually impaired people in the U.S. and of these 1.3 million are considered legally blind. The 2011 National Health Interview Survey Preliminary Report estimated that 21.2 million American adults (over 10% of all American adults) reported that they had trouble seeing even when wearing corrective lenses or that they were blind or unable to see.Only 36.8% of non-institutionalized working age adults (21-64) with a significant vision loss are employed. The Centers for Disease Control and Prevention (CDC) define "vision impairment" to mean that a person's eyesight cannot be corrected to...
Title I of the ADA limits an employer's ability to ask questions related to blindness and other disabilities and to conduct medical examinations at three stages: pre-offer, post-offer, and during employment.
When it comes to safety concerns, an employer should be careful not to act on the basis of myths, fears, or stereotypes about vision impairments. Instead, the employer should evaluate each individual on her skills, knowledge, experience, and how the visual disability affects her. 16. When may an employer refuse to hire, terminate, or temporarily restrict the duties of a person who has or had a vision impairment because of safety concerns? An employer only may exclude an individual with a vision impairment from a job for safety reasons when the individual poses a direct threat. A "direct threat" is a significant risk of substantial harm to the individual or others that cannot be eliminated or reduced through reasonable accommodation.This determination must be based on objective, factual evidence, including the best recent medical evidence. In making a direct threat assessment, the employer must evaluate the individual's present ability to safely perform the job. The employer also mus...
The ADA prohibits harassment, or offensive conduct, based on disability just as other federal laws prohibit harassment based on race, sex, color, national origin, religion, age, and genetic information. Offensive conduct may include, but is not limited to, offensive jokes, slur, epithets or name calling, physical assaults or threats, intimidation, ridicule or mockery, insults or put-downs, offensive objects or pictures, and interference with work performance. Although the law does not prohibit simple teasing, offhand comments, or isolated incidents that are not very serious, harassment is illegal when it is so frequent or severe that it creates a hostile or offensive work environment or when it results in an adverse employment decision (such as the victim being fired or demoted). Example 26:A grocery store cashier with a visual disability is frequently taunted by his co-workers. They regularly ask him how many fingers they are holding up and take away his white cane and tell him to...
The ADA prohibits retaliation by an employer against someone who opposes discriminatory employment practices, files a charge of employment discrimination, or testifies or participates in any way in an investigation, proceeding, or litigation related to a charge of employment discrimination. It is also unlawful for an employer to retaliate against someone for requesting a reasonable accommodation. Persons who believe that they have been retaliated against may file a charge of retaliation as described below.
Against Private Employers and State/Local Governments
Any person who believes that his or her employment rights have been violated on the basis of disability and wants to make a claim against an employer must file a charge of discrimination with the EEOC. A third party may also file a charge on behalf of another person who believes he or she experienced discrimination. For example, a family member, social worker, or other representative can file a charge on behalf of someone with a vision impairment. The charge must be filed by mail or in person...
Against the Federal Government
If you are a federal employee or job applicant and you believe that a federal agency has discriminated against you, you have a right to file a complaint. Each agency is required to post information about how to contact the agency's EEO Office. You can contact an EEO Counselor by calling the office responsible for the agency's EEO complaints program. Generally, you must contact the EEO Counselor within 45 days from the day the discrimination occurred. In most cases the EEO Counselor will give...

- A Word from Verywell
To be considered legally blind, you would have to meet one of two criteria for visual acuity (sharpness of vision) and visual field (the entire scope of what you can see without moving your eyes).
An eye doctor will measure visual acuity and visual field to determine if a person is legally blind. A common test for visual acuity is the Snellen eye chart. Someone who is legally blind would be able to read only the top line of the chart, a capital E while wearing corrective lenses. The line below the big E is the line for 20/100. There are also tests that can measure in between 20/200 and 20/100. Someone who cannot view 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 it is listed as "20/200 or less."8 Visual field testing often begins with a confrontational visual field test in which you an eye doctor has you cover one eye at a time and then holds up one or more fingers in different quadrants of the visual field to see if you can see them while keeping your eyes focused on a central point in front of you. There are also more comprehensive computerized tests that use flashing, flickering...
There are many conditions that can cause legal blindness, but the most common ones are age-related eye disease. Age-related eye diseases that are the leading causes of low vision and blindness are:6 1. Age-related macular degeneration 2. Cataracts(cloudiness of the clear lens of the eye) 3. Diabetic retinopathy 4. Glaucoma Eye trauma or injuries and genetic conditions, such as Usher syndrome, can also lead to legal blindness.
Treatments for legal blindness vary depending on the cause and the stage of the disease. For age-related eye diseases, it typically involves prescription medications or eye procedures to try to delay or keep the vision from worsening. For example, the goal of treatment for glaucoma is to reduce eye pressure. This can be achieved with prescription eye drops or oral medications, laser procedures, and, in severe cases, surgeries to try to prevent further damage. Careful monitoring of glaucoma and other age-related eye diseases is important for determining if treatment is working or needs to be adjusted. Cataracts are the exception in that vision can be restored with surgery to remove the clouded lens and, in most cases, replace it with an implant.
Low vision or legal blindness can be limiting to be sure, but there are many resources and assistive devices to help you live your life with the utmost independence. Depending on the cause of your vision loss, you may be able to benefit from eye exercises and strategies for participating in everyday activities. You also may find using a cane, talking calculator, special computer software, and other products designed to support people who are legally blind to be helpful.10
