Glasses that don't fit right can be just as uncomfortable and awkward-looking as ill-fitting clothing. Selecting the correct size frames will ensure that you look and feel your best. Your frame size consists of three components: eye size, bridge size, and temple size. Our frame size guide as well as the video below can show you how to find these measurements on your current pair of eyeglasses or sunglasses.

Frame color, material, shape, and detailing all play an important role when it comes to eyewear styles.

5. Know Your Prescription Type

Buying Eyeglasses Online: Know Your Prescription Type

Do you need single-vision or multi-focal (e.g. bi-focal, tri-focal, or progressive) lenses? Knowing your lens type beforehand will help ensure that you select the correct lens materials and that you enter your prescription information correctly.

  • Single-vision lenses are typically prescribed for people who are either near-sighted or far-sighted, but not both. Single-vision lenses only have one corrective power.
  • Multi-focal lenses are usually prescribed for people who have difficulty seeing things up close and far away. These lenses have two or more different corrective powers. Bi-focals and tri-focals have visible lines separating the various corrective powers. Progressive lenses do not have any visible lines.

6. Choose a Lens Material to Match Your Prescription & Lifestyle

  • Polycarbonate: High-impact resistant lenses. Recommended for children, athletes, and people with active lifestyles. Good for prescriptions up to +/- 4.00.
  • High Index 1.67: The thinnest and lightest of all the materials. Recommended for people with high prescriptions as well as those concerned with comfort and fashion.

Buying Eyeglasses Online: Appropriate Lens Coatings

There are a variety of coatings that can be added to any lens. Understanding your options will help you make the right choices for your lifestyle.

  • UV Coating: Regardless of your age or prescription,'s opticians recommend only buying lenses with a protective UV coating in order to shield your eyes from the sun’s harmful UV rays.
  • AR Coating: If you spend a lot of time on the computer or are bothered by the glare of lights when driving, then you may want to consider an anti-reflective (AR) coating. The AR coating will improve the clarity of your vision and help ease eye fatigue.

8. Know Your Pupillary Distance (PD)

Buying Eyeglasses Online: Know Your Pupillary Distance

One of the most important parts of your prescription that doctors often forget to include is your pupillary distance (PD). Pupillary distance is just what it sounds like: the distance (in mm) between the pupils of your eyes. This measurement is important because it ensures that the center of your corrective lenses is placed directly in front of your pupils.

Be sure to ask your eye doctor to write down your PD if you're going to order glasses online. Depending on whether you need single-vision or multi-focal lenses, your doctor may write your PD as one or two numbers. If you can't reach your eye doctor, we can help you determine your PD using another method. Watch the video above to learn more about PD.

9. Understand Your Prescription Information

Buying Eyeglasses Online: Understand Your Prescription

Entering your prescription online is probably easier than you think. It's simply a matter of entering the correct numbers in the appropriate fields. Don’t worry if you do not see any numbers listed on your prescription for some fields, like "prism" and "base." Not everyone needs this kind of correction, so you can simply leave those fields blank.

Below are a few key terms you may need to know when entering your eyeglasses prescription online:

  • OD: Stands for "oculus dexter," which is your right eye.
  • OS: Stands for "oculus sinister," which is your left eye.
  • DV: Stands for "distance vision." Used when multi-focal lenses are prescribed.
  • NV: Stands for "near vision" (sometimes referred to as "add"). Used when multi-focal lenses are prescribed.
