Choosing the right frame size when shopping online can be difficult especially when you can't try on a pair to see how it looks.
But don't worry, there isn't much to it.

The illustration above shows how frame measurements are interpreted.
The first number represents the lens diameter. The second, is the bridge width. And the third one, is temple length.
We recommend that you use the measurements of any current or old eyeglasses when choosing the right size for your new pair of Magic Specs™. This information can be found on every glasses' temple or bridge.
But in case you don't have any glasses to use for reference, take out a measuring tape or ruler to get your measurement (in millimetres) from cheekbone to cheekbone. After that, use the chart below to find out the recommended frame size for you.

NOTE: This guide is for recommendation purposes only but no two heads are the same. Glasses fit may differ from person to person so we recommend that new customers do not buy more than two pairs on their first time purchase.
