Copy this information (see above image) into our online prescription form
and it will look like this (below):
Note, you can leave the PD - PUPIL DISTANCE empty and
we will use the average PD value (63mm). But highly we recommend you use
the (DOWNLOAD
PRINTABLE RULER) or any normal ruler to measure the
PD (see more details below for explanation). |

Different
types of prescription lenses available:
- Single
Vision Lenses have only one viewing area throughout
the lens. This corrected area can be for far distance,
near distance or reading.
Bifocal Lenses have two distinct
viewing areas within the same lens; the distance
area and the near area. The distance area in
bifocals is designed like a single vision lens,
while the near area contains the distance prescription
and the additional amount of ADD power needed
to see at a reading distance.
Varifocal Lenses correct
vision for two or three different
distances without the visible segment
lines seen in bifocal lenses. Instead
they have a graduated section in
which the power of the lens progresses
smoothly from one prescription to
the other, allowing the wearer to
see clearly at all distances.

by the cylinder requirement).
The measurement indicates
the number of degrees on
the axis of the lens that
are required.
A + or – sign indicates the measurement.
PD - Pupil Distance:
This measurement is used to accurately center the lenses in the frame
that you have selected. PD is the distance from the center of the
pupil (black circle) in one eye to the center of the pupil in the
other eye. If you are unable have your Pupil Distance measured
by optician, you can try our (PRINTABLE
MILLIMETER RULER).
(please note
that you will still need to contact your optician to
get accurate Near and Dist PD measurements, required
only for bifocal and verifocal lenses)
