1. Choose Your Frames
Purchasing eyeglasses online starts with choosing your frames. This is usually the most time-consuming part of the process, as it involves the most personal choice. If you already have a frame in mind, you can type it in the search bar and find the color you want. If you don't have a frame in mind, choosing your frames is a little easier when you keep the following things in mind:


Frame Shape
You are likely well aware of the most and least flattering clothing styles on your body. You can say the same thing about eyewear.
Certain frame shapes will compliment your features, while others may emphasize the wrong attributes. The good news is you can
usually predict the best frames for your face using your face shape.








Frame Size
A too-narrow frame will tend to make your face look wider, while a too-wide frame will make your face look narrower. While you may choose an over- or under-sized set of frames for stylistic reasons, it is generally best to find a pair of frames that fits you well. To this end, you will want properly sized frames.


Reading Your Frame Size
To ensure your frames fit perfectly, first determine which size frames are best for you. The best place to start is with the eyeglass measurements on a pair you already own.
First, search for the three little numbers on the inside of the temple of your glasses. Some may also refer to this section as the "arm" of your glasses. These three numbers are the frame's measurements.
.


From left to right, these eyeglass measurements appear in the following order:
1. Lens width
2. Bridge width
3. Temple length
Sometimes a fourth number will be noted on the arms, which is your lens height. Keep in mind that all of these measurements are in
millimeters.


Frame Color
Frame color is the last thing to consider when choosing a set of frames, but it can be one of the most important things in determining the style and overall look of your new eyewear. This is all up to your keen eye and deciding what looks best on you. Most frames come in several colors so you will never feel trapped in choosing one color on a frame you love.


2. How to Add a Prescription to Glasses
Once you have selected the types of frames and lenses you want in your glasses, the next step is customizing your frames and lenses to your unique specifications with your prescription.
Knowing how to read an eyeglass prescription is essential! While you likely know whether you’re nearsighted, farsighted or have astigmatism, determining that from your prescription slip is another thing entirely. That’s why we’ve put together a short guide to help you learn how to read a glasses prescription so you can get to ordering your new set of eyeglasses as quickly as possible.


What do all these letters and numbers mean?
The numbers on your eyeglass prescription describe precisely how your glasses lenses should be cut. Keep your prescription up to
date so these numbers can accurately reflect your visual needs. Typically, you’ll see several abbreviations and words labeling all of the important data on your prescription. See below to learn the meaning of SPH, CYL Axis, Prism, PD, and more.


OD vs. OS Eye
OD is short for the Latin term oculus dexter which means right eye.
OS is an abbreviation of the Latin oculus sinister which means left eye. You’ll often see this terms on eyeglass prescriptions.


Sphere, Cylinder, and Axis on Eye Prescriptions
Sphere: The sphere (SPH) on your prescription indicates the lens power you need to see clearly. A minus (-) symbol next to this number means you’re nearsighted, and a plus (+) symbol means the prescription is meant to correct farsightedness.
Cylinder: The cylinder (CYL) number indicates the lens power needed to correct astigmatism. If this column is blank, it means you don’t have an astigmatism.
Axis: An axis number will also be included if you have an astigmatism. This number shows the angle of the lens that shouldn’t feature a cylinder power to correct your astigmatism.
PD, or pupillary distance, refers to the distance in millimeters between the center of one pupil to the center of the other.
Having a correct PD on your glasses prescription ensures that you are looking through the ideal spot in your lenses. If this
number was not provided on your prescription by your eye care professional, you can measure it yourself.



3. Choose Your Lenses
While the look of your glasses is important, their functionality is crucial. The quality and features of your lenses contribute most to your satisfaction with your eyewear, and you should pay particularly close attention to the options available to you. The lens thickness you choose is an important first step.


What are high index lenses and what's the difference?


High index lenses are thinner, more powerful lenses. They're lightweight and stylish, but are mostly reserved for those with higher vision correction needs. While most prescriptions are compatible with more than one specific index, it's up to you to decide which one fits your personal needs!
The difference between your glasses' lens index can make a huge impact. Deciding which you should get depends on your prescription and your lifestyle. Thicker lenses are more affordable, but can only accommodate lower vision correction needs. Thinner lenses are lightweight (and more stylish!) and can accommodate MANY kinds of vision needs, including higher prescriptions. In terms of balancing price and quality, 1.67 index polycarbonate lenses accommodate most prescriptions and are extra durable.




How do I measure my PD?
Measuring your pupillary distance (PD) is super simple. While you can probably have your local optometrist help you measure it, you can also do it yourself! Just follow these easy steps on our special "How to Measure Pupillary Distance guide".

FAQ


What is a strong eye prescription?
The higher the number on your prescription, the stronger your prescription is. A number with a minus symbol before it means you are nearsighted, and a number with a plus symbol, or no symbol, means you are farsighted. A number over 5 is generally considered to be on the stronger side.
Is astigmatism hereditary?
Astigmatism is often present at birth, but it can develop, or become more severe, as you get older.
What are high index lenses made of?
High index lenses are made with a particular type of plastic that refracts light more effectively than standard index lenses.This usually means that they can be cut thinner than other lenses while providing perfect vision correction for stronger prescriptions.
Do high index lenses make eyes look smaller?
High index lenses cause less distortion than lower index lenses with the same prescription. If your prescription is high and your lenses are large, it can result in your eyes looking smaller or larger, depending on whether you are near or farsighted. High index lenses reduce this effect.
Why are high index lenses so expensive?
High index lenses are usually more expensive than lower index lenses because they’re made with more costly materials. The benefits of high index lenses make the extra cost worth it, though!
Why are my glasses lenses so thick?
If your eye prescription is high, your lenses will need to be cut thicker to correct your vision correctly. Luckily, choosing higher index lenses for your glasses means they can be thinner and still correct your vision perfectly.
Do I need high index lenses?
If you have a high eyeglasses prescription, high index lenses are recommended to ensure that your lenses are as thin as possible.As well as looking good, thin lenses reduce the total weight of your eyeglasses, making them more comfortable to wear for long periods of time.
Where is my PD on my prescription?
Your PD number will be in the ‘PD’ or ‘pupillary distance’ section of your eyeglass prescription. This is often separate from the ‘grid’ section of your prescription - where the doctor writes out the main prescription information.
Does PD affect frame size?
Your PD has no effect on the size of your eyeglass frame. The PD number influences the shape of your lenses, but not the frame.
Does PD change over time?
A person’s pupillary distance will change when they are young as they are still physically growing. Once we reach maturity and stop growing, our pupillary distance will change very little, if at all.
