You are administering a Snellen chart test to a patient. What results would you expect to get if your patient was legally blind?
  1. 20/20 vision
  2. 20/40 vision
  3. 20/60 vision
  4. 20/200 vision
Explanation
Answer: D - The patient would be considered legally blind if the result of the Snellen chart test is 20/200 vision. This means that the patient is able to read at 20 feet what a person with normal vision can read at 200 feet. Legal blindness is defined as 20/200 or less with corrected vision or visual acuity of less than 20 degrees of the visual field in the better eye.
