How do I pick my frame?
You have 2 choices:
1 - Easy & Quick - we did all the work for you:
Simply search for frames that have your PD assigned. We took the time to measure all the parts of the frame and calculated the ideal PD for you. However, you can always pick a frame different
from your PD, in this case we automatically de-center the lens so that the optical center of the lens is in front of your iris.
Q: Why would I pick the exact Frame PD if Peerless Optical suggests I can pick any frame?
A: If you desire the most uniform lens edge thickness. The stronger your prescription the more important it is
to pick an exact Frame PD match. What are the
factors that can affect lens edge thickness? First of all it is the strenght of your prescription as well the lens type, CR-39 is more affected by this optical phenomen than Poly or Hi-Index
lenses. Why is nobody else publishing this important information? We at Peerlress Optical are certified opticians and in the eyeglass business for over 25 years, we strive to give you

How do I read my eyeglass prescription?
PD:
The PD of your prescription is the Pupulary Distance or the distance between your eyes, usually given in millimeters.
This measurement is used to perfectly center the lenses in the frame of your choice. Possible reason to find more than one Pupil Distance is the need to correct both near and distance vision.
In this case the prescription will state Near PD and Dist PD. The Near PD measurement is shorter than the Distance PD by 2 to 5 mm because the eyes turn in at near distance.
SPHERE:
Refers to the amount of nearsightedness or farsightedness . If your sphere number is negative, you are nearsighted. If it is positive, you are farsighted. Sphere
numbers of zero are called "plano" or abbreviated "PL".
CYLINDER:
Refers to the amount of astigmatism. If no astigmatism is present, then the prescription will only have a number for sphere. Cylinder can be expressed as either a positive or negative number.
AXIS:
Refers to the direction on the clock hour of the astigmatism.
ADD:
Additional plus power in the lower portion of a multifocal lens (progressive or bifocal) that is required for near vision.
What are the different lens types?
Depending on a particular eyesight disorder, a different rx lens can be prescribed. Peerless Optical opticians offer 3 types of prescription lenses: single vision, bifocal and progressive.
