How to Determine Your Segment Height

While it's possible to measure your segment height yourself using a mirror, we recommend enlisting the help of a friend or family member if possible.

  1. Put on your glasses and stand 8 inches (20 cm) away from the mirror or your friend.
  2. Face the mirror straight on and hold the ruler vertically between your nose and pupil.
  3. Align the ruler at the 0 mm mark with the bottom of the lens (IMPORTANT: ensure you measure from the bottom of the lens and not the bottom of the frame).
  4. While keeping your gaze straight ahead, read the millimeter mark in line with the center of your pupil – that is your Segment Height.
  5. Repeat these steps 3 or 4 times to ensure accuracy.
