When using a lensometer (lensmeter) to neutralize a lens, the mires are brought into sharp focus. For a spherocylindrical lens, in what order are the power meridians found?
-
A
The first clear focus gives the sphere power; the second clear focus gives the sphere + cylinder power
-
B
The first clear focus gives the cylinder power; the second gives the sphere
-
C
Both meridians focus simultaneously at the sphere power
-
D
The cylinder is read first when the mires are rotated to 90°
