Cocoons OveRx sunglasses are designed to be worn over your prescription glasses. To achieve the perfect fit that is both comfortable and secure, you need to find the size that most accurately fits your eyewear.  It is important to find the correct size, or you may not experience the full benefits enjoyed by millions of Cocoons owners worldwide.  To find the right size, we offer both an online sizing calculator and printable sizing guide to choose from:

1. Click HERE to download the Cocoons Sunglass Sizing Guide. The document is in Adobe PDF format so you will need Adobe Reader or an equivalent software to view the document.  Click HERE to access the Adobe website and download Adobe Reader for free.

2. The sizing guide MUST be printed at 100% actual size, or it will not provide an accurate recommendation of the size that will fit over your glasses.  It is important to set your print preferences with the scaling option turned off.  This will ensure that the document prints at full size.  Use the image of the coin on the sizing guide to verify it printed at 100%.  The image should be the same size as an actual US quarter or should measure 24 mm in diameter if you do not have a coin to compare.

3. Hold your glasses face down on the full scale images of each Cocoons sunglass size.  If your glasses fit inside the red guidelines, then you can wear that size. If the width or height of your glasses extends outside of the red box, then you will need to try the next larger size.
