On a typical prescription, you will see two sets of rows. Most of the time top portion is for your OD or right eye while the bottom portion is for your OS or left eye.

For Distance correction, there should always be a value under Sphere and most of the time it is negative. Its abbreviation is 'D.V.' which stands for Distance Vision.

For Reading-only correction, there should always be a value under sphere and most of the time it is positive. If there is a value under Near Vision (N.V., N.V.O.) then enter the power in the BOTTOM half of the form and leave the ADD power blank or ("0.00").

For astigmatism correction, please note that that Cylinder (CYL) and Axis are always provided together. For any value of Cylinder there should always be a value for Axis. Some doctors use positive (+) cylinder and some uses negative (-), there is a big difference between the two so please pay close attention to the positive and negative signs. If you don't have astigmatism correction, doctors might just leave it blank or simply SPH or DS which means Sphere or Diopters Sphere. Axis should be from 1-180 degrees, if you see a value like '5' under axis, this is also the same as '005' or '5 degrees'. It should always be a whole number and there should no be decimal point on the axis.

For Bifocals, Progressive lenses and Freeform lens, please check with your eye doctor whether the Addition is for Bifocals, Progressive and Freeform lens. Most of the time, compared to the Bifocal Addition, the Addition of the Progressive and Freeform is higher by 0.25, so please verify. An indication to know if your prescription is for Progressive and Freeform, is a PAL note written on the prescription. Only one ADD, means the addition for the Left and Right eyes are the same. Please be advised that we process a minimum of +1.00 and maximum of +3.50 for Addition powers.

Eye Doctors will sometimes leave out the decimal point on the Sphere, Cylinder and Addition. For example, -25 or +175, this is understood -0.25 and +1.75. Very importantly, pay close attention to plus and minus sign as this will greatly affect the lens. If there is anything on the prescription you are not familiar, please contact our Customer Service and we will be happy to assist you.

To purchase a pair of prescription glasses, all you need is your eyeglass prescription. We also recommend that you provide your pupillary distance (or PD) . We will follow up with you via email if we have any questions about your order or if we need any additional prescription information.

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. 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.

Of course! You can email us a copy at service@GlassesShop.com , upload it to our website during the checkout process. 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.

Unfortunately, we are currently unable to fill prescriptions with prisms (indicated by the word "base," an up arrow, or a triangle symbol on your prescription). For the time being, here's an option that may work if you have a pair of www.glassesshop.com in mind: simply purchase the frames without prescription lenses (at a 10% discount) and take the glasses to an optical shop to have prism lenses inserted.

Our team reviews every single order for prescription glasses. If we come across anything out of the ordinary or clearly incorrect, we will email or call you to clarify. Keep in mind that because prescriptions can differ greatly from person to person, we are unlikely to catch prescription entry errors unless you have provided us with a copy of your prescription (which you can do by either uploading a scan or picture of it during checkout, or emailing the file to service@GlassesShop.com after placing your order).

Definitely! Once you've picked the frames you like, you can proceed to checkout as usual. If purchasing optical glasses, you'll be given the choice to purchase the glasses with non-prescription lenses. We will then fill your frames with high-quality lenses that include anti-scratch coating. If purchasing sunglasses, you can choose prescription or non-prescription glasses by selecting the appropriate option when adding the frames to your cart from the product page.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 Sunglasses For sunglass orders, we can fill prescriptions with a combined SPH and CYL value up to -5.00. However, some of our smaller sunglass frames can accommodate slightly stronger prescriptions. We encourage you to contact us at service@GlassesShop.com , to determine the best frames for you based on your prescription strength.

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 your glasses.
