Understanding your RX
To place an order, you will need a prescription for corrective eyeglass lenses and your pupillary distance (PD). A contact lens prescription cannot be used to make eyeglasses.
When you have your eyes examined, request the PD (pupillary distance) from the person who does your exam. The pupillary distance is the distance in mm between the centers of your pupils. Corrective lenses can’t be made without a PD. It’s used to position the optical center of the lens so that you will be able to easily see through the lens, and to center the correction in front of the pupil of your eye in the eyeglasses. If a pair of frames cannot accept your PD, you can’t simply change your PD simply to make it work because you will not be able to see through a lens produced with an incorrect Pupillary Distance.
The correct PD is particularly important for a multi-focal lens (bifocal and progressive), as there are multiple viewing fields which are adjusted on the basis of the PD supplied.
The PD is often left off the prescription, although it’s usually recorded in your file. Having your PD empowers you to purchase eyeglasses from any supplier, not just with the place where you got your exam. It is your right to have your PD – you paid for it with your prescription.
PDs may be indicated in a variety of ways. You will often be given a single number – this should be your distance vision PD and is what you will need for eyeglass orders on our site. Most adults have a PD between 53 and 70, and children will be between 41-55. You might be given two numbers such as 63/60. This would mean that you use 63 as your PD for distance vision. The smaller number would be used only when converting the prescription to single vision reading glasses. You may be given fractional PD measurements, right side and left side, and split PDs may be written as 30.5/31, for example. Simply add the two numbers together to get your distance vision PD.
SPH – Spherical – Provides the depth of the focal field in the lens.
A negative sign in front of the number indicates that you’re nearsighted, which is the case with the majority of people who wear corrective lens. In nearsightedness, the thinnest part of the lens is the center, and the wider the lens becomes, the thicker it will be at the outer edge. If you’re concerned about the outer edge thickness of the lens, you would be advised to consider narrower lens widths.
With a positive sign preceding the Spherical number, you’re farsighted, and the thickest part of the lens is in the center. The size of the lens is also important, because the larger the the lens, the thinner the edge will be. This may eliminate the consideration of half rim frames because the lens may become too thin to provide for the groove, to carry the filament, to help keep the lens in the frame.
Cyl and Axis – The two designations will be included if you have an astigmatism, an irregularity in the shape of the eye, which causes shape distortion in the viewed image. Cyl will describe the amount of correction you need to overcome this, and Axis is the angle at which the correction is placed. The Axis will be recorded as a degree reading between 1 and 180 degrees.
If you find the designation “Sph” written in the Cylinder area of the prescription, it simply means that the eyeball is spherical, and there is no correction for astigmatism needed in that eye.
Extra Strength If you are ordering a single vision pair of glasses, and the prescription strength is beyond the corrective capacity of a standard lens, an extra strengh charge per pair of glasses will apply depending on the lens type and strength of correction. When you enter the prescription values in any of the four data entry fields (OD Sph, OD Cyl, OS Sph or OS Cyl), and an extra strength charge is warranted, the Configured Price at the upper right -hand of the page will indicate the added charge.
NV-Add (or simply Add)- This is the reading portion of a lens in a multi-focal prescription, and this number indicates the strength of the overlay on the lens, for reading. It is the same positive number for both eyes, and it may be written only once on your prescription. The ADD can be found in the ADD sectionof the prescription, and is often annotated “NV,” as in “near vision.” It may also be written as a large, positive number, across both the OD and OS lines of your prescription.
Please be advised that if your spherical corrections are very minor, making your “Add” the strongest corrective part of the prescription, you may find that the design of a lined bi-focal is more suitable to your need, rather than a progressive (unlined) lens, as well as far more comfortable to wear. The reason for this is that your area of greatest need, is minimized in the design of a progressive lens (approximately the lower quarter and central third of the lens, 13-16mm in corridor width), while the lined bi-focal provides a larger, clearly delineated portion of the lens, for reading and other close work.
Seg Height – In our multi-focal lens, the segment heights produced are standard. In a bi-focal lens, it’s approximately 40% up from the bottom of the lens; in a progressive lens, the segment height is approximately 48% up from the bottom of the lens. The actual physical height, of course, will be determined by the height of the lens chosen. In most instances, if personal adjustment is desired, it may be achieved by simply opening or closing the nosepads or changing the position of the frame on the bridge of the nose.
If you’ve had your eyes examined by a licensed Optometrist or Optician, they are required by law to provide you a complete written prescription. If you wear a multi-focal prescription, it’s in your best interest to ask for the basic, underlying multi-focal prescription (even if you simply want a single vision lens for a different purpose).
Multi-focal prescriptions may be modified for single vision use, or even a different multi-focal use, by working with the Sph and Add numbers. If there is a correction for astigmatism in one eye, or both eyes, those designations will not change, regardless of the depth of the focal field.
Single vision distance only –Enter values for Sph, Cyl and Axis for both eyes, but leave off the Add number. Use the distance PD value.
Single vision reading glasses – Combine the Add and Sph numbers for each eye. The result creates the new Sph values for each eye. In the case of a Positive Add and a negative Sph, net the difference, and the new number becomes the Sph. If your Sph is already positive, you simply combine the positive Sph and the Add number, using it for the new Sph. The Add data entry field will be blank, by virtue of it having been combined with the Sph number. Enter Cyl and Axis values for both eyes- these values are not changed in any way. For single vision reading only, narrow the distance vision PD by 3mm and enter that as the single-vision reading PD value.
Single vision computer glasses – Split the Add number in half, and combine that split number with the Sph. Discard the remaining Add, and leave the Add data entry field blank. Enter the Cyl and Axis values for both eyes. These values are not changed in any way. Use the distance PD.
Multi-focal Computer/Desktop glasses – To create this modification, split the Add number in half (if there is no equal division of the Add number, you’ll need to decide if you want your focus closer or further, and the quarter diopter difference will shift the depth of the focal plane, accordingly) and combine half of the Add with the Sph. The balance of the Add will stay in that data entry field. Note: We do not create a multi-focal lens with an Add of less than +1.00. Use your distance PD, unless your monitor is extremely close (less than 18”), in which case, you may wish to narrow the PD by a millimeter or two. Finally, enter the Cyl and Axis values for both eyes. These values are not changed in any way.
Prism Corrections – We do not prepare prism corrections.
Glasses Without Correction in the Lens – It is quite possible to order eyeglasses with no prescription in the lens. You simply leave the prescription data entry fields defaulted to zero, but you will be required to enter a PD, to get the computer to process the order. Use 63, as it is a median number for an adult. It’s a good idea to include a note at the end of the order, in the Customer Comments section, indicating that this is an order for a pair of glasses with no correction in the lens. A pair of glasses ordered in this manner will have an optical lens, and may be worn.
NOTE: If you have questions about any of these modifications, you’re welcome to email us at firstname.lastname@example.org and we will be happy to help with your questions. It is better to ask, than to order incorrectly.
All of our glasses come equipped with polycarbonate lenses with high index ratings of 1.56 (Standard thin lite), 1.6 (Super thin lite) and 1.67 (Ultra thin lite). Polycarbonate lenses are not only 35 % lighter and thinner but also about 10 times more resistant to impact than other plastics or normal glass. Polycarbonate lenses also offer complete protection from the sun’s harmful UV rays. Their durability, effectiveness, and comfort of the material make them the lenses of choice.
Moreover, all our lenses come with a 100% accuracy and satisfaction guarantee! We will also automatically include the following coatings for FREE.
Scratch- resistant coating
All of our lenses come equipped with a scratch-resistant coating that will extend the life span of your lenses by reducing the small scratches that can generally occur in daily usage. This scratch-resistant coating will produce a harder surface and will ensure your lenses stay free of scratches that may obscure your vision or cause discomfort.
Our premium Anti-Reflective coating eliminates glare by maximizing light transmissions through the lenses providing the clearest and sharpest vision at all times. With our quality anti-reflective coating your lenses will always appear clear to the outside, letting people see your eyes and not a light reflection.
100% UV protection
We are exposed to the sun’s harmful UV radiation daily which over long periods of time can cause health issues. With 100% UV protection built into the lenses we can eliminate the sun’s ultraviolet radiation and as a result protect your retina and the lens of your eyes.
100% 24-Month Guarantee
If you have any problems with your lenses within 24 months of purchase we will either refund your money or fit new lenses into your glasses*. This means that if you experience any problems with your glasses such as the coatings or your lenses becoming loose, we will attend to your concerns promptly and do our best to ensure long-term satisfaction!
Guarantee & Return Policy
If you’re not 100% satisfied with your glasses (whether they’re prescription, non-prescription, or sunglasses), we offer a no questions asked, 30-day return policy from the day you receive your order. For orders within the US, free return shipping is also included. We also have a one-year no-scratch guarantee for our lenses, and will replace your lenses free of charge if they have scratched within one year of receiving them.
Unfortunately we cannot provide returns to customers outside the contiguous US. However, if you choose to exchange your glasses, we are happy to help you with that.

Please email us at firstname.lastname@example.org to find out more and to discuss your needs.
Can you replace the lenses in my existing frames?
We are happy to put new lenses into your existing frames. Lens replacements cost $80 for optical polycarbonate lenses, $100 for ultra-thin 1.67 high-index lenses (optical only), and $100 for sun lenses — much less than the cost of buying new high-quality lenses at an optical shop! Just email us at email@example.com. We’ll then fit them with new lenses and ship them back to you — all within 10 days.
Do you accept Insurance?
While we do not accept insurance, many customers are able to obtain reimbursement for a portion or all of the cost of their prescription glasses through their insurance provider, and we are happy to provide a receipt for this purpose. We recommend that you email us at firstname.lastname@example.org once you receive your order if you would like to obtain a receipt.
What forms of payment do you accept?
For purchase orders, we accept all major credit and debit cards as well as Paypal.
Can I pay using my Flex Spending or Health Savings Account card?
Yes, as long as your FSA or HSA card is affiliated with a major credit card. If you would like to use your FSA or HSA card to pay for a portion of your purchase, and apply the balance to a different credit card, please email us at email@example.com.
What is a Flex Spending Account?
A Flexible Spending Account (FSA) allows employees to set aside pre-tax money from their paychecks to spend on healthcare expenses not paid for by their current insurance policy.
What can I use my Flexible Spending Account funds on?
You’re eligible to purchase both prescription eyeglasses and prescription sunglasses using your FSA.
How long do I have to use the funds in my Flexible Spending Account?
If you don’t use all of the money you’ve put in your FSA for the year, you lose the money that’s in your account when the plan year ends. Most FSA plans end on December 31, but your plan may offer a grace period until March. Please check with your employer to find out the terms for your plan.

I have a strong prescription — can you fill it? What if I have astigmatism?
We can fill a wide range of single vision prescriptions, including prescriptions with astigmatism. However, we do have some limitations.
Prescription Optical Glasses
Sphere (SPH): We cannot fill prescriptions with an SPH value stronger than -10.00 or +6.00. If you do not have astigmatism, the SPH will be the only value on your prescription (no CYL or Axis).
Cylinder (CYL): If you have astigmatism in either eye, you will have a CYL value in your prescription. We cannot fill prescriptions with a CYL value stronger than ±4.00.
While the above SPH and CYL values are at the extreme ends of our range, our ability to fill your prescription depends on your specific combination of SPH and CYL values. If your SPH is stronger than -8.00 in either eye and you also have a CYL value, please email us at firstname.lastname@example.org. We would love to discuss your prescription in detail to determine whether or not we will be able to provide you with prescription lenses.
For sunglass orders, we can fill prescriptions with a combined SPH and CYL value up to -7.00. However, some of our smaller sunglass frames can accommodate slightly stronger prescriptions. We encourage you to email us at email@example.com, to determine the best frames for you based on your prescription strength.
What is my pupillary distance (or PD), and how do I get it measured?
Your PD is the distance in millimeters between the centers of your pupils. We use this measurement to align the optical center of the lens with the center of your eye in order to avoid unnecessary eye strain.
Measure your PD quickly and easily by watching this video: Measure your PD
Your PD may already be on file with your doctor or the last place that made your prescription glasses. If not, the measurement can also be done at any optical shop or optometry practice. The measurement is usually taken for free, but if you are charged a nominal fee we will cover it by deducting that amount from your order. All you have to do is send us a receipt and we’ll take care of the rest!
Can I use my contact lens prescription to order glasses?
Unfortunately, contact lens and eyeglass prescriptions are different. The simple reason is because contact lenses sit directly on your eyes, while eyeglasses are held in front of your eyes. Though the prescriptions may appear similar, they will differ in strength and are not interchangeable. We cannot — and, for your safety, would not — use your contact lens prescription to make you glasses.
I’m unsure about how to enter my eyeglass prescription online. Can I send it to you instead?
Of course! You can email us a copy at firstname.lastname@example.org. When you send us your prescription, please include your name, email address, and order number so that we can match up the prescription to the correct customer or order record.
If you have any questions about your prescription, please email us at email@example.com.
I see the letters “DS” or “SPH” written in the Cylinder column of my prescription — what does this mean?
This is essentially a fancy way of saying that you do not have a Cylinder or Axis measurement in one or both eyes. While most people will have measurements in their Sphere column for both eyes, you will only have a Cylinder measurement in either eye if you have astigmatism in that eye. If you don’t, your doctor will either leave that column blank, or will write “SPH” or “DS” to make it clear that you only have a Sphere measurement for this eye. If you have any questions about your prescription, please email us at firstname.lastname@example.org.
Can I just order frames without prescription lenses?
Definitely! Once you’ve picked the frames you like, you can proceed to checkout as usual.
