Glasses size: Where can I find the exact measurements of my glasses?

Whether it's myopia glasses or sunglasses, there are three basic dimensions to consider: the width of the lens, the width of the bridge, and the length of the arm. These measurements are marked on the inside of the arms or bridge of the glasses and are expressed in millimeters.

The width of the lens is the most important measurement, as it directly affects the overall size of the glasses. It usually ranges from 40 mm to 60 mm and determines whether the size is for kids, small, medium or large. The width of the bridge, located between the two lenses, determines the distance of the glasses that fit on your nose and ranges from 14 mm to 24 mm. Finally, the length of the arm, measured from the blinking point to the tip, affects the comfort and stability of the glasses and ranges between 120 mm and 150 mm.

To find the ideal size, you can compare the measurements with the following categories:

40-46 mm: X-Small (children's size).

47-48 mm: Small (adult small size)

49-53 mm: Medium (adult size)

54-61 mm: Large

62 mm and above: X-Large (extra large size)

If you lose your glasses or need a new pair, you can easily refer to the inner markings of your previous glasses to find the right size. Choosing the right size will ensure a comfortable fit and the best protection for your eyes.
