First, what does it mean to be “legally blind”? In most states, if you have less than 20/200 visual acuity that cannot be corrected with glasses/contact lenses, you are legally considered “severely visually impaired” (which was called “legally blind”). But the trick here is not what you see “naturally” (with the naked eye), but how well you see with your glasses or contact lenses. Despite such a high correction of myopic lens, if one or both of your eyes can see 20/40 or better, you are not “legally blind”. However, it`s easy to see how someone might feel this way when you`ve lost glasses somewhere! The conditions of right blindness and complete blindness vary widely. Whether you are legally blind or not can affect a variety of things, from your ability to get a driver`s licence to disability benefits. For this reason, it`s important to understand if your eye prescription is considered legally blind. 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 cannot diagnose yourself with the condition. Your doctor needs to make this call, so let him or her know if you have any eye problems. If you are legally blind, organizations like the American Foundation for the Blind can help. They have programs to help you cope with the physical and emotional effects of vision loss. Being legally blind affects your eyesight, but that doesn`t have to stop you from living a fulfilling life. Eye prescriptions may change over time. Gradual changes in visual acuity are normal because the flexibility of the natural lens changes over time.

Total blindness is the complete absence of light perception and shape perception and is recorded as “NLP”, an abbreviation for “no light perception”. “Normal” vision is 20/20. A person with 20/20 vision can stand 200 feet away from an eye map and see it as clearly as a legally blind person sees it 20 feet. Third, let`s say your -9.25 eye can see 20/20 with a contact lens, but the -12.50 eye can only see 20/40, even with the best contact lens available. We would say that this last eye has some amblyopia and is therefore not entirely correctable at 20/20, whether with glasses, contact lenses, a lens implant or LASIK. This doesn`t mean you can`t treat such severe myopia, but it does suggest that you should be prepared in advance that one eye is slightly better than the other, even with full refractive correction. For example, the goal of glaucoma treatment is to reduce eye pressure. This can be achieved with prescription eye drops or oral medications, laser procedures, and in severe cases, surgery to prevent further damage. Careful monitoring of glaucoma and other age-related eye conditions is important to determine if treatment is working or needs to be adjusted. 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.

Eye trauma or injury and genetic diseases, such as Usher syndrome, can also lead to legal blindness. People often ask about the difference between being blind and being “legally blind.” Because “blindness” can mean many different things, blindness under the law is the threshold at which a person is considered visually impaired for legal purposes, such as insurance purposes, to receive certain benefits, or to be accepted into various programs. Few people today are completely blind. In fact, 85% of all people with eye diseases have some kind of vision; About 15% are completely blind. 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. 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. 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.

An ophthalmologist will measure visual acuity and visual field to determine if a person is legally blind. Before talking about prescription that is legally blind, it is important to examine what legal blindness really is. To put it simply, legal blindness is measured by looking at your central visual acuity (essentially how you see what`s in front of you) and your field of vision (how you can see to the sides, above, and below you). “Legal blindness” is a definition used by the U.S. government to determine eligibility for job training, rehabilitation, education, disability benefits, equipment for the visually impaired, and tax exemption programs. It`s not a functional definition of low vision and doesn`t tell us much about what a person can and can`t see. The definition of legal blindness is used as a guideline to enable these individuals to receive government assistance, such as social security disability benefits. Similarly, the Department of Motor Vehicles has established this recipe as the line in which it is no longer safe for you to drive.
