Segment Height Instructions

You can take this measurement with a mm ruler in front of a mirror with your frames on, or have a friend help you. 

1.  Stand 8-10 inches in front of the mirror with your frame on.

2.  Facing the mirror straight on, hold the ruler vertically with the zero at the center of your pupil.

3.  Still looking straight ahead, read the measurement at the bottom of the lens, not the bottom of the frame.  This is your segment height/optical center.  This will be the same for both eyes.
