How to know or measure the size of a frame?

 

To ensure your frames fit perfectly, first determine which size frames are best for you. The best place to start is with the eyeglass measurements on a pair you already own. There are usually three small numbers marked on the inside of the temples of the glasses, which are the size of the frames.

 

54 □18-140

From left to right, these numbers represent

1.Lens width 54□18-140

This is the horizontal width of each lens at its widest point.

 

2.Bridge width 54 □18-140

The bridge width is the space where your frames fit against your nose.

 

3.Temple length 54 □18-140

This is the length of the temple from each screw to its temple tip, including the bend that sits on your ear.

 

*Keep in mind that all of these numbers are in millimeters.
