"The American Optometric Association states that a person with 20/20 vision can clearly identify a row of 9mm letters from 20 feet. A legally blind person with vision of 20/200 has to be as close as 20 feet to identify objects that people with normal vision can spot from 200 feet. So a legally blind person needs a distance of two feet to spot the letters on a standard eye chart that is 20 feet away."

The legal term, however, has something to do with one's vision as described above but that it CANNOT BE CORRECTED. If it can be corrected, it falls under low uncorrected vision or something like that. I read this in a legal brief a few years ago.

20/200 or less in the better eye is pretty much the standard for legal blindness so whatever that works out to be. I used to wear -4.0 until I got Lasik. I had to squint to read the newpaper headlines on the table and no one ever told me I was legally blind so it's more than that.

I don't know the limits, but I am -4.75 on my right eye and -5.25 on my left , and I am legally blind.
