Glasses consistently receive the status of the most popular accessory. Sun protection aids are especially in demand with the arrival of spring and summer. In addition to choosing a fashionable style, it is important to correctly determine the size of glasses. Otherwise, you can only dream about comfortable wearing. Let's figure out how to choose your sunglasses number.
Sunglasses sizes and meaning of numbers
Classification of optics sizes depends on the width of the face their owner. The so-called width of the lens or light opening is subject to measurement, depending on which further calculations are made.
Important! The full size is the sum of the width of the glasses, that is, the width of the lens multiplied by two (since the glasses have two such glasses) + the length of the nose bridge between them. To the resulting width it is necessary to add the size of the hinges, which ranges from 2 to 6 mm on each side. Therefore, it must also be added in double meaning. The second dimension indicator is the length of the bow.
Four characteristics for glasses
Fans of solar protection optics have noticed a combination of three or four numbers printed on the inside of the left temple.
Some manufacturers print indicators on the bridge of the nose or on product packaging.
These mysterious numbers - main characteristics of the accessory, on the basis of which it is possible to decide on the appropriate size:
- first digit - the same lens width;
- second indicator - size of the jumper between the lenses;
- third number — the length of the temple from the lens to the temple;
- fourth indicator They don’t always indicate, they indicate the height of the frame.

Cheat sheet for lens size and number
Branded and sports glasses are most often produced in three sizes:
- 54-55 mm. Glasses with the specified lens size are produced for people with narrow faces. Most often, sophisticated, fragile girls and teenagers fall into this category. For children, a separate line of accessories with a special mark is usually produced.
- 58 mm refers to standard. The vast majority of owners of sun protection optics wear this particular size. It is logical that the most popular brands produce all product lines in this size, while slow-selling sizes are available only in the most common models.

- Glasses sliding down the bridge of the nose if the arch is too long and imprints on the bridge of the nose if it is too short.
- Pressure in the temples as a sign that the width is too small for the owner of the accessory.
- Nose holders should not leave marks on the bridge of the nose or squeeze it.
An incorrectly chosen size can lead to negative consequences for the owner of the glasses, such as dizziness or headaches. This is why it is so important to decide on the width of the frame, especially when purchasing optics online.
