Most visually disabled people retain some usable vision. The levels for qualifying for a driver's license are different than the definition of legally blind. For instance, my state requires vision correctable to at least 20/40 in one eye, and a FOV of at least 60 degrees to drive without special bioptic lenses (basically a monocular that attaches to a pair of glasses.) To be classified as legally blind (at least in the United States) you must have vision that cannot be corrected to better than 20/200, or a field of view of less than 20 degrees. It gets complicated because you can be on disability even if you don't meet the definition of "legally blind" if you have vision issues that cause you to be unable to work. This is on a case by case basis and requires a hearing in front of a disability judge.
