What the GM8 measures

Measure

The GM8 measures monocular and binocular PD, fitting height, frame width, lens wrap, temple width and the corridor length a frame allows.

Pantoscopic tilt

A tilt sensor clips to the frame and reads the forward tilt, one of the values a progressive order can ask for.

Complete set

The set includes a measuring frame, PD scale, occluder, pantoscopic tilt ruler, marker, case, near chart and manual.

Measured on the real frame

Values are read on the frame the customer chose, adjusted as it will be worn.

Buyer’s guide

Measuring for a progressive

Measure in the chosen frame

Progressive values belong to a frame: the fitting height depends on where the pupil sits in that frame, and the corridor must fit between the fitting cross and the bottom of the lens. Mount the GM8 on the customer’s new frame, adjusted as it will be worn, then read the monocular PD, the height, the wrap and the tilt.

Good practice

  1. Adjust the new frame on the customer before measuring anything.
  2. Measure PD and height with the customer looking straight ahead at distance.
  3. Mark the fitting cross on the demo lens with the marker.

Check before you order
