Knowing Your Frame Measurements

Knowing your frame sizes will allow you to purchase prescription glasses that not only fit well and are comfortable to wear but will also look good too as they will be in proportion to your face.

Frames have 3 basic measurements:

1) Eye size.
2) Bridge size.
3) Arms/temples size. 

All of our product pages have the frame size on them using the images below and the size in mm:



How to find them:

Firstly, all frames will have these 3 sizes written on them either on the inside of the arms, or written behind the bridge.

Secondly, if you can’t see the numbers as they've worn away, then simply get a ruler and measure them using the image guide below, it’s very easy to do.

Additional Measurements:

The above measurements are the industry standard and will be written on all frames.

There are 2 additional frame sizes, provided by us on all product pages, which you can easily measure yourself and will help you to find the perfect fitting frame.

4) Frame width:

a) Simply measure the width of your existing frame


b) Measure the width of your temples

5) Lens depth:

As the name suggests, it is the depth of the lens from top to bottom.

You will need to measure an existing frame to get this measurement.
