If you wear glasses, you may have noticed a series of numbers on the inside of the frame. These numbers may seem confusing, but they actually provide important information about your glasses. In this article, we will explore what the numbers on glasses frames mean, how to read them, and why they are important.
The Basics of Glasses Frame Numbers
The numbers on glasses frames typically consist of three sets of numbers separated by dashes. The first set of numbers represents the lens width, the second set represents the bridge width, and the third set represents the temple length.
- Lens Width: This is the horizontal width of each lens in millimeters.
- Bridge Width: This is the distance between the two lenses in millimeters.
- Temple Length: This is the length of the temple arms that extend over the ears in millimeters.
How to Read Glasses Frame Numbers
To read the numbers on your glasses frame, simply look at the inside of the temple arm. The numbers are usually located near the hinge of the glasses. The lens width is the first number, the bridge width is the second number, and the temple length is the third number.
For example, if the numbers on your glasses frame read 52-18-140, this means that the lens width is 52 millimeters, the bridge width is 18 millimeters, and the temple length is 140 millimeters.
Why Glasses Frame Numbers Are Important
The numbers on glasses frames are important because they help ensure that your glasses fit properly. If your glasses are too small or too large, they may not provide the correct level of vision correction, and may be uncomfortable to wear.
By knowing your glasses frame numbers, you can ensure that you choose glasses that fit properly and provide the correct level of vision correction. Additionally, knowing your glasses frame numbers can make it easier to order glasses online, as you can simply enter the numbers into the ordering form.
How to Choose Glasses Based on Frame Numbers
When choosing glasses, it is important to consider the frame numbers to ensure a proper fit. Here are a few tips for choosing glasses based on frame numbers:
Lens Width
Choose a lens width that is appropriate for your face size. If you have a small face, choose a lens width of 50-54 millimeters. If you have a medium face, choose a lens width of 55-57 millimeters. If you have a large face, choose a lens width of 58-62 millimeters.
Bridge Width
