Frame Guide

Steve Mower - April 2019

About Eyeglass Frames - Frames come in different sizes, materials, and styles. Selecting the right frame for you is important. You want them to fit comfortably and look great. Learn about different frame materials, hypoallergenic frames, eco-friendly frames, and more...



Optical frame sizing is the industry standard for eyeglass frame measurements. Measurements are in millimeters (mm) It works like this:

Lens Width - Bridge Width - Temple Length:

50 - 18 - 140 for example.

Optical quality eyeglass frames have this information printed on the inside of one of the temples. If you multiply the eyesize by 2 and add the bridge width, you get a general idea of the total frame width in millimeters.

50 x 2= 100 + 18 = 118mm.

Adding 10mm to the total is a bit more accurate as it includes the average frame extension to where the temples extend from the frame front. So, +10mm = 128mm total for the example above.

We even have tools for converting mm to inches.


In addition to optical frame sizing we provide Frame Fit which gives you a better idea of how wide the frame is. Some frames have small lenses but wide bridges and fit wider than you might expect. Frame Fit looks like this:

  • Extra Small (42-45)
  • Small (46-48)
  • Small Medium (48-50)
  • Medium (49-52)
  • Medium Large (53-55)
  • Large (55-56)
  • Extra Large (56 and over)

Use our product filter to select the fit/size range you need. For helpful images and tips on determining the right sized frame see:

Our goal has always been to offer the highest quality eyeglass frames for the best prices. The frame lines we offer are from independent frame manufacturers. There are certain popular brands you won't see on our site. This is because those brands are all owned by one company, a monopoly, and they have set frame prices way to high across the industry.

Most of the eyeglass frames you see on our site are made in the same factories with the same materials. Popular lines from manufacturers like Value Eyewear are priced way lower than what you will find in stores and at other websites.

Certain features like spring hinges and special frame materials will reflect in the price. Why do designer frames cost a lot more? Generally the "brand name" is the major factor but also. usually, the workmanship and detailing are part of the reason.

A couple of things to consider while shopping our site: Reading lenses are free! Prescription single vision lenses are only $10 more!
