If your eye has a visual acuity of 20/200 or less when best corrected, then this is considered legally blind. This reading is recorded as a result of wearing corrective lenses during the exam and testing again with the patient’s best eye.
What vision qualifies as legally blind?
When someone is legally blind with a vision of 20/200, their field of vision is less than 20 degrees. In other words, a person who is legally blind can see an object from 20 feet away that a person with normal vision could see from 200 feet away.
What vision score is legally blind?
