The witness was allegedly suffering from advanced glaucoma at the time of the crime, severely limiting visibility. Surveillance video from the scene also revealed the eyewitness was much farther away than he initially claimed to be, according to the Exoneration Project.

    So what does it means “Legally blind” if he can drive and read? What’s the threshold to be considered legally blind?

      Found this definition;

      In the United States, legal blindness means your central visual acuity—the part of your vision that allows you to see straight ahead—is 20/200 or less in your better eye when wearing corrective lenses. With 20/200 vision, you can see at 20 feet what a person with 20/20 vision sees at 200 feet. Or, your 20-degree field allows for seeing only right in front of you.

      You can be legally blind with tunnel vision, i.e. you can see directly ahead, but nothing out of the corner of your eye.
