What are the main causes of blindness? According to the National Eye Institute, there are four main causes of blindness in the United States. 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. Another way of looking at it: if someone with 20/20 vision is standing next to a legally blind person, the legally blind person should approach up to 20 feet to see an object from 200 feet away, as well as the person with normal vision. There are many conditions that can cause legal blindness, but the most common are age-related eye diseases. Age-related eye diseases, which are the main causes of low vision and blindness, include: Did you know: The largest letter on the map (an E on most Snellen diagrams) is equivalent to 20/200 vision. If someone cannot distinguish this letter with his prescribed glasses, he is considered blind within the meaning of the law.

Finally, even if both eyes could see 20/20 with correction, would LASIK be a good idea? I don`t think so.
Most reputable and experienced ophthalmologists will not do LASIK above about -8 because there will be so much thinning of the cornea, late stability problems are a definite potential problem. These can be serious. A hit-and-run ophthalmologist could go ahead and do it, knowing that they will be gone long before this problem occurs. A LASIK clinic may not care, because if the problem arises as long as they are paid: they will blame the surgeon and ophthalmologist and pretend to be just the place for the doctor`s office.

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. 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. 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. 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. While low vision or legal blindness can be limiting, there are many resources and tools 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 to participate in daily activities. You may also find it helpful to use a stick, talking calculator, special computer software, and other products to help people who are legally blind.
This term refers to someone who cannot see at a certain level. Most health care institutions and government agencies agree that if your best eye vision is 20/200 with correction, then you are legally blind. Being considered legally blind means you can`t drive in any state. Talk to your doctor about your concerns. 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.
