Sizing Your Face for Sunglasses, a Step-by-Step Instructional Guide

Sizing Your Face for Sunglasses, a Step-by-Step Instructional Guide-Seek Optics

Finding a great pair of sunglasses is like striking gold. Knowing how to take accurate measures is the key to designing a space that is not only practical, but also comfortable and aesthetically pleasing.

There are, thankfully, a few simple approaches that may make this task a snap. Are you wondering where to start? Read on for a breakdown of the various methods of measuring shoes and how to interpret the size information printed on your present pair.

Using a Ruler to Determine the Proper Size of Sunglasses

Finding out the circumference of your head is the first step in ensuring that your sunglasses fit properly. Knowing this figure, generally expressed in millimeters, allows you to choose the optimal size of glasses for your face without having to worry about the lenses being too large or tiny.

A straight ruler may be used as a measurement tool for selecting the right pair of shades (as opposed to a tape measure or something similar). Put the ruler in front of your face, millimeter side up, just below eye level. You should position the ruler's ends so that they are flush with your temples on both sides of your head. Take a measurement across the widest part. To determine the ideal sunglass frame size for your face, measure its circumference in millimeters.

Tips on Alternative Sunglasses Sizing

Don't stress if you can't find a ruler. If you don't have a measuring tape handy, a credit card will do the trick. Take the following actions:

- Get out your charge card now.
- Place yourself in front of a full-face mirror or camera.
- Put your credit card in between your eyebrows, on the bridge of your nose. The result should be a L shape extending from the bridge of your nose to the top of your head.
You are generally considered to be of small size if the corner of the card extends over the outer corner of your eye. If it rests on the outside of your eye, you have a medium-sized head. You are considered as large size if it sits nearer in than your eye. 

Finding an old pair of sunglasses that fits you well is another option for determining your correct sunglasses size. If the serial numbers are still legible, they might serve as a guide for selecting a new pair of sunglasses or a replacement pair of lenses. However, you should take these measurements with a grain of salt since the way in which various brands create their sunglasses may affect how they fit you.

Guide to Understanding Sunglass Sizing

There is often size information included with sunglasses. Check the arms or temples of your present pair to see whether they have this feature. A set of numerals reading 55-19-145 should be seen on the temples. Lens width, bridge width, and temple length are all listed in millimeters and should be pretty self explanatory.

In spite of the fact that all three measurements provide insightful data regarding total size, bridge width is the most critical. Your sunglasses will still fit nicely with a little variation in temple length and lens width.

The horizontal distance from one lens edge to the other is known as the lens's breadth (at its widest). The width of the bridge, which rests on the wearer's nose, may be anywhere from 14 millimeters to 24 millimeters, depending on the size of the lenses. It is the whole distance from the sunglass frame to the wearer's temples that is referred to as the temple length. Common temple measurements range from 135 to 145 millimeters.

The distance from the lens's apex to its base is an important dimension to consider as well. It varies from around 32 millimeters to about 38 millimeters. All of these dimensions are, as you would assume, brand-specific.
