Legal blindness relates to the best corrected vision after an eyeglass prescription is determined. You cannot look at the numbers on your eyeglass prescription to determine this. If the best you can do on an eye chart, with the best eyeglass correction, is 20/200, that is legal blindness in most states in the usa.
In the United States you are considered legally blind if your best-corrected visual acuity (meaning, your best distance vision with eyeglasses or contact lenses) is 20/200 or worse. To get a driver's license in most of the United States, your best-corrected visual acuity must be at least 20/40.
