Buying the right glasses is not an easy task. Especially when it comes to online stores. Here you should know your own norm and base your purchase on it. How to recognize it will be discussed in the written article.
What are the sizes of glasses?
It makes sense to know in advance that the value corresponds to the width of the lens. And for convenience, they also usually measure the distance of the bridge on the bridge of the nose, the frame, the length of the lens and the temple. If you have information about the listed parameters, you can successfully select an accessory. The most common values are:
- Small - forty range. Most suitable for people with narrow faces.
- Average - fifty-eighth. It is considered a popular option, as it is in greatest demand among buyers.
- Big - sixty-second. As is already clear - for broad-faced representatives.
In addition, the scale directly depends on the type of eyepiece. For example, rectangular models include values from 47 to 55. Drop-shaped models include 55, 58 and 62. And round models include 40, 47, 49, 50, 52, 53, 55 and 56.Thus, when purchasing, it is advisable to correlate the design with the type of product.
How to find out your glasses frame size
Try to take any model from the described accessory and turn to the inside. In most cases, you can find on the left temple not only the brand, but also the size of the product.
Reference! Some manufacturers mark the information on the nose bridge. Thus, this is the most significant indicator that is recommended to be taken into account when choosing.
The cipher itself consists of three or four digits. The first two are separated by a dash, and the last two by a dot. But they are all units of measurement presented in millimeters. What each of them represents will be described below in the article.
Now it’s worth understanding how it is possible to independently determine individual indicators. Since the markings may wear off and become visible over time, it is necessary to be able to use the following illustrations as a guide. Most often, the overall width of the frame helps in this matter. It includes the distance that is determined from the edge of the bow to the main area. Often the significance corresponds to a gap of two to six millimeters on each side. Therefore, the total is approximately from 4 to 12. After which the definition of the front parts and the bridge is added up. In addition, you can use a slightly different method. In this case, you need to arm yourself with a ruler and go to the mirror.
Important! For accuracy, it is recommended to attach a pencil to each ear. Now, in front of the mirror, you need to measure the gap directly between the left and right parts.
Using the described method, the result can be a general format in centimeters.If you want to order accessories online, do not forget to take into account the error. It can vary + - three mm from its own coefficient.
Unlike optical samples, sunglasses do not require such strict attention. However, when ordering, it is also enough to take certain aspects into account. Even if you are absolutely sure of your choice, it is still advisable to go to the nearest store and try on a similar option. At the same time, remember its relationships and make sure that the indent is reasonable.
Decoding the size of glasses frames
As mentioned above, data can be discovered from the inside. They will be presented as several numbers. Most of them consist of three points. The essence, of course, does not change depending on how they are depicted and separated from each other: be it a dash with dots or an image of a square. So, let's say, if you saw the markup at 62.10.140, then follow these principles:
- The first designation is glass. It is measured in latitude, namely, horizontally across its larger section. Therefore, in our situation – 62 mm.
- The second reflects the essence of the bridge of the nose, which connects the two areas. In the example this is 10 mm. In the absence of this sign, it is best to measure the distance between the glasses. Often this aspect is not given due attention and in vain. Since each person’s nose differs in shape and more.
- And the last thing is the length of the arch. It is predetermined from the loops to the end of the line. In the provided moment – 140 units.
Some manufacturers equip them with a fourth feature - frame size, which means a complete design standard. This is done to give the buyer comfort and accuracy in the determination. So, you can say for sure whether the accessory is suitable or not.In conclusion, you need to understand that established designations tend to vary. If 52 – 18 – 135 suits you, then stick to the ratio 47 – 19 – 130. Since in the main lobe a change of +-5 mm is permissible, and in the bridge +- 1 mm.
