Place a portion that is slightly lower than the center of the lens on the nosepiece. The target ( displayed. ) indicating the distance portion is The arrow shows the direction in which the lens should be moved. Tips on moving the lens: To measure progressive power lenses accurately, pay attention to the following: Move the lens vertically after horizontal alignment of the lens. Move the lens while the frames are constantly in contact with the lens table. Ensure that the lens rear surface is constantly in contact with the nosepiece. 44

55 OPERATING PROCEDURE Measuring Progressive Power Lenses 2) Move the lens in the horizontal direction to align the target with the vertical line of the crossline. 2 3) Slowly move the lens inward (upward on the screen) referring to the target to align it with the crossline. When the target is off the vertical line of the crossline in the horizontal direction while the lens is moved, move the lens in the horizontal direction. When the vertical position is roughly aligned, the arrow disappears. 4) Precisely adjust the lens vertically and horizontally to align the target with the crossline until the target changes from to (cross). 5) When the target changes to (cross) and measured data stabilizes, the measured data is automatically fixed. The Distance measurement complete message appears. The screen changes to ADD power measurement for the near portion automatically. When the Dist. auto RD parameter is set to Off, press the read button when the target changes to (cross) in Step 5) and the measured data stabilizes. When the distance portion cannot be detected in normal measurement, bring the distance portion onto the center of the nosepiece, and then press the read button. For progressive power lenses corrected with the horizontal prism, the position of 3 mm upper from the pupil for the distance vision with glasses is marked as distance portion. In such a case, press the read button manually. The near portion can be measured in the normal procedure. 45

56 OPERATING PROCEDURE Measuring Progressive Power Lenses 5 Measure the near ADD power. 1) The target indicating the near portion appears. The arrow shows the direction in which the lens should be moved. 2) Move the lens slowly in the direction of the arrow (towards the operator). When the intermediate portion (progressive zone) is detected, the Conducting near measurement... message appears and the current ADD power (Add) appears. The indicator for near portion ( ) appears above, below, on the right of, or on the left of the target, which shows the direction and movement distance to move the lens. Move the lens in the direction of ( ). The number of indicators (up to three) shows how much the lens should be moved. 3) Align the lens horizontally. Move the lens in the horizontal direction until the indicator for near portion ( ) on the left or right of the target disappears. 4) Align the lens vertically. Move the lens in the vertical direction until the indicator for near portion ( ) above or below the target disappears. Move the lens in the vertical direction after horizontal alignment of the lens. When the indicator for near portion appears on the left or right of the target, perform horizontal alignment again. Perform vertical alignment of the lens ensuring that the indicator for near portion is not displayed on the left or right of the target. When the indicator for near portion above the target does not disappear: For small vertical frames, the indicator for near portion may not disappear due to steep variations in lens powers even though the lens is moved towards the operator. In such cases, press the read button to measure the lens with the lens table at the front. 46

57 OPERATING PROCEDURE Measuring Progressive Power Lenses Whether to display the indicator for near portion ( ) can be set with the Indicator parameter. When the Indicator parameter is set to Off, align the lens referring to the target. When the vertical position is aligned, the arrow disappears. After horizontal and vertical alignment of the lens, the target changes from to (cross). 2 5) Precisely adjust the lens vertically and horizontally to align the target to the crossline until the target changes from to (cross). 6) When the target changes to (cross) and the measured data stabilizes, the data is fixed automatically. The Near measurement complete message appears. When the Near auto RD parameter is set to Off, press the read button when the target changes to (cross) in Step 6) and the measured data stabilizes. When the near portion cannot be detected in normal measurement, bring the near portion onto the center of the nosepiece, and then press the read button. 6 Measure the other lens if necessary (in the R/L state). Press the L-selection button or R-selection button to specify the left-eye or right-eye lens. Follow the same steps as the first lens. 7 Press the print button to print out the measured results (, transmit the data, or write the fixed data to Eye Care card.). For details of printing, see 2.11 Printing (LM-600P/LM-600PD only) (page 69). 47

58 OPERATING PROCEDURE Measuring Progressive Power Lenses Auto R/L selection works after ADD power measurement. Measurement screen in the single state When the lens side is not specified (single state), a round lens is displayed in form on the screen. The measurement procedure is the same as when the lens side is specified. Screen change in auto measurement When the lens on the nosepiece is detected as a progressive power lens on the auto measurement screen (normal measurement), the screen changes to the PPL measurement screen (auto measurement mode) automatically. 1) Set a progressive power lens onto the nosepiece on the auto measurement screen. Place the intermediate portion (progressive zone) that is slightly lower than the center of the lens or near portion area onto the nosepiece. When the distance portion is placed on the nosepiece, the lens may not be detected as a progressive power lens. The progressive power lens detection is continuously performed while the lens is set on the nosepiece in auto measurement mode. 48

59 OPERATING PROCEDURE Measuring Progressive Power Lenses 2) The screen changes to the PPL measurement screen automatically. 2 After lens measurement, pressing the print button or clear button returns the screen to the auto measurement screen (normal measurement). Progressive power lenses for small vertical frame When the height of the processed lens is too small for the near portion to be included, the display changes to alert that the proper near power has not been measured. When the edge of the lens is found before the near portion is detected, a small lens image is displayed on the screen. At this time, the lens image and measured ADD value are displayed in red. The near ADD power is fixed by the auto read function, and measurement completes. If the lack of near portion is detected when the Near auto RD parameter is set to Off, the near ADD power is automatically read. The ADD value is printed out with an exclamation point for attention. An exclamation point is added. 49

60 OPERATING PROCEDURE Measuring Progressive Power Lenses When the height of the processed lens is small and near portion is lacked, the ADD power cannot be measured with the usual auto read function. When the height of the processed lens is sufficient When the height of the processed lens is small The near portion is lacked from a lens shape. For such lenses, measure the point which is nearest to the near portion with the auto read function. The measurement point is out of the near portion, so the measured data is not near power of the original uncut lens. Measurement point (Nosepiece position) The measuring procedure is same as normal lenses, but note the following things. Be sure to move the lenses in the vertical direction when the indicator for near portion ( ) is not displayed on the right and left sides. Otherwise, the ADD power may be underestimated. Align the nosepiece so that more than half of it is covered with a lens. When the nosepiece is widely out of the lens, a measurement error occurs. The lack amount of the ADD power cannot be judged. Consider the additional power acquired with this function as lower than actual. 50

70 OPERATING PROCEDURE Marking 2.10 Marking Marking at the optical center Marking is performed to indicate the optical center position and axis direction. To measure the PD of mounted lenses, mark a lens at the optical center of both the righteye and left-eye lenses. Measure the distance between the marked center points. For simple astigmatism lenses such as S 0.00 D and C D or equivalent, the target cannot be moved in the bus direction. Mark a lens at the geometric center in the correct direction. 1 Set a lens on the nosepiece. 2 Align the lens. Move the lens until the target changes from to (cross) and then from (cross) to (large cross). (large cross) shows that the lens is within 0.8 mm in diameter from the optical center where marking is allowed. 3 When the lens contains cylindrical power, set the cylinder axis according to the prescription. While watching the axis value, rotate the lens until the prescribed axis value is displayed. When the Auto RD S or Auto RD R/L parameter is set to or, the measured data will be automatically fixed after the target is aligned. Watch the axis value displayed in the upper-right of the target. When (large cross) changes back to (cross), align the target again. For the axis of 90 or 180, the shape of the target changes as shown to the right. AXIS 90 AXIS
