First let's start with understanding size! Most people understand the concept of small, medium and large, but unfortunately that's not how it works here. We all have our own unique facial features that require specific frame measurements in order to be both comfortable and flattering.
Understanding size is a major key when shopping for glasses on the internet and we want to make sure that you are an educated shopper!
Did you know that the size of your glasses can be found on your glasses?
Go find your favorite frames and look inside the temple (the part that goes over your temple and ear) and look for numbers that look like the following set of numbers:
All eyeglass frames are measured in millimeters (mm).
Using the diagram below you can understand the numbers above:
51 = the width of the lens
20 = the distance between the lenses (DBL) aka “the bridge”
145 = the length of the temple
Sometimes there is a fourth number that refers to the lens height.
These numbers are very useful and can act as a reference during your online decision making process.
Below are definitions of some common terms as seen in our measurement diagram. Knowledge of this information will be helpful when considering which glasses frames might fit you.
The Temple Length is the measurement from the screw to the end of the temple, including the bend. It is also known as the “arm length" of the frame. Temple length can range between 120mm and 155mm. The most common lengths are 135mm, 140mm, 145mm and 150mm. If you have problems with temples being too short, you will want to stick to frames with lengths of 145 and 150mm. When buying eyewear be sure to remember that the temples can be adjusted by bending them either straighter or more curved to find comfort around your ear. Any local optician can help you with minor fit adjustments.
The Frame Width From one side of the screw measures to the other side of the screw. It gives you a sense of a frame's overall width. Frame width is usually the most important factor in finding a pair of glasses that not just fit well but also highlight the individual's unique features. As a golden rule, your eyes should be nearly centered in the width of the lenses. A frame that is too wide will make your eyes look close together, while a frame that is too narrow will make your face look much bigger and wider.
The maximum width of the lens size in the frame, measured from the bridge. The width is limited by the frame style so if you personally favor wider lenses, you will need to go for frames that wider lenses fit in.
The maximum height of the lens size in the frame which is measured from the tip to the bottom of the lens aperture of the frame. This measurement is especially important for bifocal lenses or progressive lenses.
Bridge width is the gap above your nose between the lenses. It’s the shortest distance between the lenses, typically ranging from 14mm to 24mm. If you have a narrow bridge or your eyes are a close set, you will want this number lower (15mm to 18mm) and if you have a wider bridge or a wide set eyes, you will like to have a higher number (18mm to 22mm).
Remember, when buying new eyeglasses, it's always best to refer to the frame size from your favorite pair of glasses. The closer you are to the numbers that fit you best; the more educated of a shopper you will be!
