Distance Chart

• 1). Stand up or sit in a chair that is 20 feet from the eye chart. In a doctor's office the distance may be simulated using mirrors. Your body and gaze should be facing the chart.
  
  
• 2). Remove your glasses if you are wearing them so that you can check your vision free of any correction. Cover your left eye with your hand or an eye occluder.
  
  
• 3). Starting at the top of the chart, use your right eye to read the letters or numbers one line at a time. As you read the chart, each consecutive line will be smaller in size.
  
  
• 4). Stop reading when you come to a line that you are unable to read or that you feel you must strain to read.
  
  
• 5). Uncover your left eye, and use your hand or the occluder to cover your right eye.
  
  
• 6). Read down to the smallest line that you are able to read, using your left eye only.
  
  
• 7). Uncover your right eye. Using both eyes, read the eye chart as far down as you can.
  
  

Jaeger Near Reading Chart

• 1). Hold the reading card comfortably at a distance that you would normally hold your reading material, between 12 to 16 inches.
  
  
• 2). Cover one eye at a time and read the smallest line on the card. When checking your vision one eye at a time, hold the card at the same distance for each eye.
  
  
• 3). After reading with each eye individually, read to the smallest line of numbers using both eyes.
