Print to Fit Guides for Clip-Ons & Flip-Ups

Printable sizing guides are available for all of our clip-on and flip-up eyewear.  Each sizing guide is a downloadable PDF document. To open the document, please click on the image of the sizing guide you need.

First, identify the shape (Oval, Round, Rectangle, or Square) that most resembles the shape of your prescription eyewear frame. Then print out the page(s) that includes the available sizes for that shape. Next, place your glasses face down on the full scale image(s) of each size within the shape collection to find the size that is most accurate to the shape of your glasses.  It is important that the shape of the clip-on or flip-up closely matches the shape of your glasses for an appropriate fit.

IMPORTANT: The sizing guides MUST be printed at 100% actual size, or they will not provide an accurate recommendation of the size that fits 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. Each sizing guide document includes a reference image of a coin or a credit card outline to help verify that the document has printed at 100%.
