LOINC long common name : Lensmeter Sphere measurement increment;
LOINC short name : LM Sphere increment [InvLen];
LOINC description : Sphere measurement increment is the specificity to which a lensmeter can measure the
sphere diopter, typically 0.25 diopters, but may be as small as 0.01 diopters. For
example, a 0.25 diopter increment allows measurement of 0.25, 0.5, 0.75, 1.0 diopters,
etc., while a 0.01 diopter increment allows finer measurement to a hundredth of a
diopter.;
