Before you begin following the instructions on this page to order your new prescription glasses, you should have your prescription and your Pupillary Distance (PD) in front of you. Both are required to order prescription glasses.
Your PD is the distance in millimeters from the center of one pupil to the center of the other pupil. This measurement is important because it tells us where to center the prescription on your lenses.
If your PD is not written on your prescription, you may contact your eye care professional to ask for it, or you may click here to learn how to easily measure it at home. Our order page will ask for either a Single PD or a Dual PD. If you are not sure whether to select Single or Dual, we can help you with that. Just click here to learn the difference.
After you find a frame you love, click "Select Lenses", then follow the instructions below to order your prescription eyeglasses.
Most prescriptions will look like the ones in the graphics below. Like the prescriptions you see here, yours may not have a value in each field. Your doctor would have filled out only the ones that are necessary. If your prescription has a value in the field marked ADD, like the prescription in the second graphic below, skip ahead to the heading labeled Bifocal or Progressive Lenses farther down on this page. If your prescription looks like the first example, without a field marked ADD or if there is nothing in that field, continue reading just below the graphics to order Single Vision Glasses. And if you want to learn what some of the optical abbreviations on your prescription mean before you get started, click here to find out.
Single Vision Glasses
The first step is to choose Single Vision from the Prescription Type options. See the graphic below:
Next, you will select your PD (pupillary distance). If you’re not sure whether to select Single PD or Dual PD, go back up to the first paragraph, we’ve included a link there that will help you.
After entering your PD, transfer the SPH, CYL and Axis values from your prescription to the field that has the same name on our order page. See the highlighted areas in the graphic below. When you click on the small arrow, you will have the opportunity to choose from +12.00 to -20.00 for the SPH and from +6.00 to -6.00 for CYL and 0 to 180 (no plus or minus sign) for AXIS. Be sure to select the correct number and the correct sign, either positive (+) or negative (-), for SPH and CYL.
Although this is rare, you may see prism correction on your prescription. It corrects double vision. A prism correction on your Rx may be indicated with Δ, and one of these four abbreviations: BD, BI, BO, BU. The B stands for base, and the second letter stands for the direction; it could be base down (BD), base in (BI), base out (BO), or base up (BU). If you see prism correction on your prescription, click here for help with that part of your prescription.
Bifocal or Progressive lenses
If your prescription does not have a value in the ADD field, check out the first section of this page - Single Vision Lenses. The ADD value on your prescription means that it is a multifocal prescription. This type of prescription is used for bifocal or progressive lenses - lenses that can be used to see far distance and for near distance (for reading). It can also be used to order single vision reading, computer reading, or far distance glasses. If you want to use your multifocal prescription to order single vision reading glasses, click here. If you want to use it to order computer (intermediate vision) glasses, click here. Or if you want to order single vision glasses for far distance only, click here to learn how. If you want to order Bifocals or Progressive lenses, your first step will be to choose either Bifocal or Progressive No line Multifocal from the Prescription Type options. See graphic below:
Please be aware that Bifocals have a visible line separating the distance and reading focal areas.
After selecting a prescription type, you will select your PD (pupillary distance). Our order page asks for either a Single PD or Dual PD. If you’re not sure which one to choose, go back up to the first paragraph. We’ve included a link there that should be helpful.
Next, transfer the SPH, CYL, Axis and ADD (NV-ADD) values from your prescription to the field that has the same name on our order page. See the highlighted areas in the graphic below. When you click on the small arrow you will have the opportunity to choose from +8.00 to -10.00 for the SPH, from +6.00 to -6.00 for CYL, from +1.00 to +3.50 for NV-ADD, and 0 to 180 (no plus or minus sign) for AXIS. Be sure to select the correct number and the correct sign, either positive (+) or negative (-), for SPH and CYL. The NV-ADD is always positive, and although you will select it only once, the number you select will be for both eyes.
