Eyeglasses prescriptions may be written in different ways. But in general, they would be in horizontal rows and right eye(OD)on the first row and left eye(OS) on second. When fill in the Rx(prescription) form on our website, please make sure you are filling in the exact number written on your prescription.
OD: Right eye
OS: Left eye
SPH: Sphere, the sphere number with a negative sign(-) corrects for nearsighted and plus sign(+) corrects for farsighted.
CYL: Cylinder, cylinder number corrects for astigmatism. If “DS” or “PL” appears on the field of CYL, it means you have no astigmatism.
AXIS: The orientation of astigmatism. A number between 0 and 180 degrees. It only and must be included when cylinder power is included in your eyeglasses prescription.
ADD: Reading Additions, additional correction for reading used in a bifocal or progressive lens.
PD: Pupillary Distance, PD is sometimes included in your eyeglasses prescription. It states the distance between your pupils in millimeters. If your prescription does not include your PD, you may measure it yourself by following our guide here.

Not a problem. We will customize it for you and do our best to fulfill your requirement.

Simply select Non-Prescription in the vision type after clicking on “Customize&Purchase” button. Flat lenses are included in non-prescription glasses and you may still add blue-light-filtering or light-responsive add-on to them. If you just want a frame without lenses, you may click on “frame only” button.


Lens index number indicates the degree of refraction by the lens. It is related to the thickness of the lens. The higher the index, the thinner the lens.

A. If you have total spherical power under +/-4.0, our free index option 1.56 will be suitable for you and thin enough compare to other merchants who usually put 1.50 for as their free option. (The higher the index, the thinner the lens.)

B. If you have total spherical power under +/-4.0 and prefer even thinner lenses, you can have an upgrade by choosing 1.60 as your lens index.

C. If you have strong prescription which is over +/-4.0, we highly recommend you choose 1.67 as your index as it reduces lens thickness significantly.

Sure, we do! After clicking on “Customize&Purchase”, you will see blue-light-filtering option under Add-on page.

All of our lenses come with impact-resistant, anti-reflection and anti-scratch hard coating plus 100% UV protection!

How To Measure Your PD (Pupillary Distance) Quickly & Easily

Shopping for a new pair of glasses from Quinze USA? If so, you probably need to measure your PD (Pupillary Distance) so that your glasses can be fitted properly. What is PD, why does it matter, and how can you measure it yourself? Get all the details now.

What Is PD (Pupillary Distance)
And Why Does It Matter?

PD is short for “Pupillary Distance.” As you may have gathered, this refers to the distance between the center of each of your eyes (the pupil), where light enters your eye and creates the images you see.

To focus your eyes properly, each pair of prescription lenses must have an “optical center.” This is located at the center of each of your pupils, where your eye looks through your glasses. An accurate PD ensures that your glasses will provide you with sharp, clear, accurate vision.

How to Measure
Your PD in

Your PD may be included with your prescription from some eye doctors, but others may leave it off, since many optical shops will take their own PD measurements before creating your glasses.

So, how can you measure it yourself and shop for eyeglasses online at Quinze USA? It’s simple. All you’ll need is a mirror and a ruler – and to follow these 5 steps.


Find a large mirror in a well-lit area, and stand 8 inches away from it


Hold a ruler ( marked w/ cm & mm measurements ) against your brow


Close your right eye. Next, align the “0 mm” measurement of the ruler with the middle of your left pupil


Make sure you are looking straight ahead. Now, reverse this process. Close your left eye and then open your right eye


Look at the ruler using your right eye. Find the millimeter line that meets up with the middle of your right pupil. This is the measurement, in mm, of your pupillary distance (PD)!

This process is quick and easy, but if you’re not confident about your ability to measure your PD on your own and want to work with a professional, most local optical shops will measure your PD for you for free, or for a small fee.
