    OPERATING PROCEDURE: Tracing Tracing Identifying frame tracing types Tracing measures the shape of spectacle frames (hereafter referred to as frames) three-dimension- ally . In addition, patterns or demo lenses can be measured. Tracing may be conducted using the following methods. Select the desired method. Frame tracing (both eyes) Traces both eyes of general frames.

  • Page 49: Frame Tracing (Both Eyes, Single Eye)

    OPERATING PROCEDURE: Tracing 3.3.1 Frame tracing (both eyes, single eye) This is the procedure to trace both eyes or single eye (right eye or left eye) using general frames. • As distortion may occur and correct measurement cannot be obtained from frames with low stiffness, perform demo lens tracing.
  • Page 50 OPERATING PROCEDURE: Tracing Start both-eye tracing. Press . Tracing starts. When the frames are released, tracing is complete. Gently open the lower slider and remove the frames. • If is pressed while frames are being retraced after the stylus came off, two beeps may sound and tracing cancellation may not occur.

    OPERATING PROCEDURE: Tracing 3.3.3 Goggle type frame tracing Tracing sharply warped frames When frames are sharply warped, the stylus may come off the groove during tracing. In such a case, fasten only one rim between the rim clips and perform goggle type frame tracing. The FPD (Frame Pupillary Distance) cannot be measured during goggle type frame tracing.
  • Page 54 OPERATING PROCEDURE: Tracing Set frames. As shown in the picture below, do not fasten the left rim between the rim clips but hold the left temple. Fasten the right rim between the rim clips, maintain the right rim level, and then align the middle of the right rim to the dotted line position.
