What is the meaning of the numbers on your eyeglass frames and why you should care about it?

If you are wearing eyeglasses for a long time and the choice of picking up the perfect frame always confusing you? Don’t worry you are at the right place to have all the acknowledgment of choosing the perfect eyeglass frame for yourself. It might be a long time since you are wearing glasses, but have you ever looked, noticed or observed your eyeglass frames? If you have then, you might have seen tiny numbers printed on the inside of those frames.
These numbers indicate a structural meaning of your frames, and they are measured precisely. Now, if you take a close look at your glasses, you will see distinct numbers stamped on the inside of your eyeglasses. These are always printed on the inner surface of the frame temples or the bridges so that the frame’s design might not get ruined. Now imagine the numbers stamped on the outer surface of your glasses obviously you won’t like it as it will completely ruin the charismatic and fascinating design of your favorite eyeglass frame. Therefore, these numbers are always printed on the inner surface of the eyeglass frame.
These numbers are the measurements that indicate and describe the size of your eyeglass frames, specifically:
1) The eye size number (it is the size of the lenses on your frame).
2) The bridge size number (the distance between the lenses).
3) The temple length number (it is the size of that part of your eyeglass frame, which rests upon your ears).
The three mystical words mentioned above are the key measurements that describe the structural measurements of the frames in eyeglasses. For example, if you look at your glass frame, you will see three numbers separated by a dash on the inside of your frames such as 53-16-140. These numbers help the optician to choose the best-fitted frame for your head size and facial features. All of these three numbers are measured in millimeters (mm). These variations in frame numbers are fitted by a skilled optician so that it should be best fitted, be comfortable and look good on the appearance. Let’s look at these numbers one by one to get a good briefing of what they actually represent.
A first number is a two-digit number that is 53, which represents the eye size. It is the horizontal width of the lenses. Generally, the number of eye size varies from 40 mm to 62 mm in most of the spectacle frames. If you take a look at your eyeglass frame, you will see that the first number will be from 40 mm to 62 mm.
A second number is also a two-digit number that is 16, which represents the bridge size. It is the distance between the lenses. Also, it is the bridge that rests upon your nose. Mostly, the size of the bridge on spectacle frames varies from 14 mm to 24 mm.
Finally, the third number is a three-digit number that is 140, which represents the temple length. It is the length of the stems of the frame that rests upon your ears. It can be measured from the frame hinge to the end tip of the temple. The range of the temple length in most cases varies from 120 mm to 150 mm. The bridge and temple help the frame to comfortably fit on the face.
Now if you don’t have these numbers printed on the inside of the eyeglass frame then don’t worry. You can always measure your eyeglass frame with a millimeter ruler. Sometimes, the tiny numbers are worn off or sometimes they are printed too small that you might have to use a magnifying glass. You already know which part of the frame indicated what key measurements, so it would be highly easy for you to measure it yourself with just a millimeter ruler.
For instance, the eye size can be measured horizontally at the widest points from one side of the lens to the other, so does the bridge size, can be measured as it is the distance between the lenses, and the temple size is the sticks that rest upon your ears it can be measured from the tip to the hinge, which includes the bend.
Other than these three numbers on the eyeglass frame, you can see other printed material as well. Such as it can be a name, a set of capital letters, a frame model, or a frame color. Most of the time, it is the frame model and the color so you can easily tell the color of your frame and its model number. Of course, everyone wants to choose the best frames to look beautiful. This leads us to choose the best frame with charming colored frames in perfect shape that looks good on us. One thing to notice is that if you choose the identical glasses, its three numbers might still vary as the design structure can easily change these numbers. So, it is better if a trained optician helps you to choose the best eyeglass frame size according to your facial features.
The opticians have the capabilities to adjust the right size glasses for you. They are not an eye doctor; however, they use the prescription to fit and sell eyeglasses and other eyewear. Some of the opticians are well trained with an opticianry training program, and they might also have a license. Therefore, nearly all spectacle frames are constructed in a way so that they can be adjusted by the opticians. For instance, if your glasses are loose as they are slippery or getting off your nose, or they are not perfectly adjusting on to your ears then an optician can fix that for you without any worries. Now you know much about how to choose the perfect eyeglass frames that look the best on your facial appearance, you can easily choose your eyeglass without any problems.
