Accurate Progressive Measurement

1. Choose and Adjust Frame
a. when choosing a frame be aware of your B measurement (frame depth)
b. avoid frames that deeply cut away from the nasal (some aviator shapes)
c. Adjust nose pads as if dispensing frame
d. Adjust temples to straighten horizontal fit (leveling)
e. Adjust frame to fit close to eye (12 to 14mm)

3. Put frame back on Patient
a. ask the patient to stand and look at a distant object
I. observe posture and head stance
b. View the patient’s line of sight from the side it should pass through your horizontal line. Alter line if necessary

4. Measure Monocular PD’s
a. Set pupilometer at infinity
b. record results
