Power
Sometimes called 'sphere' or 'strength'. Measured in diopters, it is always preceded
by a + (plus) or a - (minus) and goes up in 0.25 increments.
BC
The shape of the back surface of the lens, which determines how the lens fits. It
is usually an 8.x or 9.x number. A few brands use non-numeric base curves such as
flat, median, or steep.
DIA
Refers to the width across the lens in millimeters. Most brands come in one or two
sizes. It is usually a 14.x number, but can range from 13.x to 15.x.
ADD
Bifocal contacts have an additional measurement called an 'add power' that assists
in bringing near vision into focus. This will be identified by either a + (plus)
number or labeled high, medium or low, varying by brand.
D/N
"D" stands for dominant and "N" stands for non-dominant.
This parameter is used to determine which eye is your dominant eye and is only
needed when purchasing bifocal/multifocal contacts.
