The width of the glasses
The width of the glasses, or the width of the frame, means the distance between the two edges of the glasses. The size of the frame of the glasses is indicated on the frame of the glasses, and it plays an importa role in choosing the frame of the glasses. It is also possible to get the size of the glasses handle from the poi where the handle is connected to the frame to its end, that is, we measure from the screw connection that connects the handle to the frame to the beginning of the bend above the ear. Then we measure from the same poi to the end of the handle and add these two values together, and in this way we get the size of the eyeglass handle.

Eyeglass bridge is another very importa number on the eyeglass handle when shopping online. Eyeglass bridge is the place where the eyeglass lenses are connected and placed on the nose. The importance of the eyeglass bridge is that it makes the glasses you choose sit well on your face, or the frame you choose is big or small for your face.
We can measure the smallest size between the nasal surfaces to calculate the eyeglass bridge. If your nose bone is delicate and thin, the eyeglass frame with the nose size of 14 to 16 mm is suitable for you, otherwise, the nose size of 17 to 19 mm is suitable for you.
The width and height of the eyeglass lens
The width of the eyeglass lens is to coordinate the position of the pupil with the lens. To get the size of the lens width, we consider the widest size of the lens, which is also called the eye size. To calculate the height of the lens, you need to measure the longest and longest part of the lens. Calculating lens height is mostly used for bifocal glasses.
In general, the information on the glasses can be used for the following purposes.

The second number is a two-digit number, which is the size of the eyepiece bridge, which connects the two lenses, and is the distance between the two lenses. The location of Aynak bridge is on the nose and its size is about 13 to 24 mm.
Finally, the third number is a three-digit number and indicates the part of the eyeglass frame that is placed on the ear. The size of the glasses frame is between 120 and 150 mm.
