To Test Visual Acuity:

• Allow the patient to use their glasses or contact lens if available. You are interested in the patient's best corrected vision.
• Position the patient 20 feet in front of the Snellen eye chart (or hold a Rosenbaum pocket card at a 14 inch "reading" distance).
• Have the patient cover one eye at a time with a card.
• Ask the patient to read progressively smaller letters until they can go no further.
• Record the smallest line the patient read successfully (20/20, 20/30, etc.)
• Repeat with the other eye.

MCC Paramedics are held to a higher standard.
