There are several measurements when it comes to eyeglasses, of which there are 5 important measurements

Here’s what you need to know.

Chances are that your current glasses have measurements engraved on the inside of the temples. A temple may contain: the brand, model name and 50 □ 19 140 , 50/19 140 or 50 19-140. These measurements indicate three frame dimensions—lens width, bridge width, and temple length. The overall frame width, however, will not be printed on the temple arm.

Once you know the measurements of your current glasses, you can easily choose the right pair of Spectaculars glasses that best suit you.
