APPENDIX: Descriptions of Power Adjustment
8
[Semi-auto adjustment]
Add –0.25 D to the spherical powers.
Adjustable within the range that the spherical powers are not negative.
This key does not function basically.
However, the spherical powers can be adjusted to the LM data only when the data is larger than the
full correction to positive.
C. Astigmatism
C.1 First glasses
[Auto adjustment]
• A certain power is reduced from each cylindrical power.
• The difference between the left and right eyes shall be within 0.75 D.
[Semi-auto adjustment]
Add –0.25 D to the cylindrical powers.
Adjustable within the full correction. When the cylindrical powers are tried to be changed out of the
range, short beeps are audible and they do not change.
Reduce –0.25 D from the cylindrical powers.
Adjustable within 0 of cylindrical powers. When the cylindrical powers are tried to be changed out of
the range, short beeps are audible and they do not change.
* When the difference between the right and left cylindrical powers is large, the powers may be
changed up to –0.25 D only. This is because the patient eyes do not adjust to the glasses well with
0 D of monocular vision.
C.2 With glasses
When the LM data has been entered:
[Auto adjustment]
• A certain power is reduced from each cylindrical power.
• When the lensometry data is overcorrected, the full correction is selected.
• The difference between the left and right eyes shall be within 0.75 D. However, when the difference in
the LM data is large, the adjusted one may be over 0.75 D.
• The amount increased from the LM data shall be within 0.75 D. However, when the difference
between the left and right cylindrical powers in the LM data is large, the increased amount may be
over 0.75 D.
[Semi-auto adjustment]
Add –0.25 D to the spherical powers.
Adjustable within the full correction. However, the cylindrical powers can be adjusted within the len-
sometry data over the full correction only when the LM data is overcorrected.
Same as [Semi-auto adjustment] of C.1 First glasses.
