The sizes of glasses
The width:
  • of the lens;
  • of the nose bridge;
  • of the frame.
The length:
  • of the lens;
  • of the ear-hook.

The size of the glasses equals the length of the lens. For more accurate choice of necessary size all the above measurements should be taken.

As a result, the following sizes are common:
  • child: size 37;
  • small: size 40, fits people with narrow faces;
  • medium: leading size 58, most popular among customers;
  • large: size 62, designed for customers with wide faces.
Marking:

On the left earpiece of brand glasses, there is an inscription on the inner side. It contains the information that should be considered when purchasing glasses.

After the name of the company-manufacturer there are 3 numbers – the parameters of glasses size in millimeters. They are separated from each other either by dashes or dots.

For example: 58 – 14 – 135, where 58 – the size that equals the lens width, 14 – the nose bridge width, 135 – the earpiece length.
