1.Choose Your Frames

If you already have a glasses 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

Certain glasses frame shapes will compliment your features, while others may emphasize the wrong attributes. You can look to How to Pick Glasses for Your Face Shape.


Frame Size

To ensure your glasses 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.

Lens Width 

This is the horizontal width of each lens at its widest point. It typically ranges from 40mm to 60mm.

How to Find the Perfect Frame Width


This measurement is not printed on the temple of your glasses. To find it, take your measuring tape and measure horizontally across the front of your glasses frames, including any hinges or design features that stick out on the sides.


Bridge Width 

This is the distance between your two lenses. In short, the bridge width is the space where your frames fit against your nose. The size of this piece ranges from 14mm to 24mm.

Selecting the Ideal Bridge Width

The distance between two lenses equals a frame's bridge width. The bridge should sit comfortably flush against your nose. If you have close-set eyes or want a narrow bridge, this number should be lower. If you have wide-set eyes or want a wide bridge, this number should be higher.

The location of your nose can help determine which frame style works best for you. If your nose is higher on your face, an eyeglass style where the bridge is even with the frames brow line will look best. If your nose is situated a bit lower on your face, a frame with a lower bridge and curved brow line will better suit your features.

To find bridge width, measure the distance between the inner edges of each lens.

Temple (Arm) Length

This is the length of the temple from each screw to its temple tip, including the bend that sits on your ear. The temple is typically 120mm to 150mm long.

Get Cozy with Your Temple Length

Temple length is the measurement in millimeters of the arms of the frame. This measurement does not vary as much as the others. 135mm, 140mm, 145mm, and 150mm are the most common options. The temple should fit horizontally and evenly along your face and fit comfortably along the outside of your ear.

To find temple length, measure one from screw to tip.

Lens Height

This is the vertical height of your eyeglass lenses at the widest point of the lens within the frame. The lens height is important when measuring bifocals or progressive lenses.

Picking the Right Lens Height and Width

To determine which lens size is right for you, know that a small lens width is 50mm or less, medium is between 51mm and 54mm and large is any lens wider than 55mm.

Your eyes should be centered within your lenses. Eyeglass frames that are too wide will make your eyes appear too close together, while narrow frames will give your eyes a wide-set look.

To find lens height and width, measure the widest or longest parts of the lens.

When you offer reading lens option do you mean the entire lens is a magnifier or is it a bifocal lens?
I need a 2.5 magnification for reading only, I want plain glass on top 2/3s.
