  • Page 54: Progressive Addition Lens Measurement

    5.1.2 Progressive Addition Lens Measurement The Cursor Cannot be Centered in the Progressive Channel. Cause 1: With progressive lenses which have a small power difference between the far point area and the near point area, aligning the cursor to the center may not be achievable. Action : The beginning of the progressive channel is located in approximately the center of the lens or the center of the frame.
  • Page 55 Cause 3: The near point area in a small frame lens may be positioned very near to the edge of the frame or even outside of the frame. It may not be possible to detect the near point area in such lenses. Action: Press HOLD button when judging the highest addition value when the cursor is in the progressive zone.
  • Page 56 Cause 2 : TL-100 senses refractive power change along the progressive extent. If the power change is close to 0 diopter, the TL-100 treats it as a near point. Example: When a lens with a SPH reading of -1.00 diopters and an add reading of 2.00 diopters is measured, there is a point where the...
