E 01-93 lating the size and position of the Purkinje images in the study of the
mechanism of accommodation. Unfortunately this method is hardly touched upon
in the standard works on Visual and Geometrical Optics. To find the dioptral
power ...
triple-line focus with the segment is +5.25, once again, we calculate the add as
the dioptral difference between these two like foci — in this case +1.75.
Measuring the bifocal add of a one-piece bifocal lens. If the segment is on the
ocular ...

Manual of Contact Lens Prescribing and Fitting
The proximity of dioptral distance of an object or image point (L) is also defined
as the reciprocal of its linear distance (f) in meters. An object in air at a distance of
f meter from a lens has a dioptral distance (reduced vergence) of L diopters.5 III.
