<p>1. Measure your old pair of glasses to get the dimensions that&nbsp;fit&nbsp;you the best. With these measurements, you can easily compare them to the frames on our website. Please see the photos below for guidance on&nbsp;frame measurements (a 2-3mm difference is acceptable).</p> <p><img alt="" src="https://df5apg8r0m634.cloudfront.net/email/2019/1225/ttomel2W9229g0ks.jpg" /><img alt="" src="https://df5apg8r0m634.cloudfront.net/email/2019/1225/F2rKzgUQaU8pg17s.jpg" /> &nbsp; &nbsp;&nbsp;</p> <p>&nbsp; Diagonal length refers to the&nbsp;diagonal measurement of each lens, corner to corner.&nbsp;</p> <p>&nbsp;</p> <p>2. You can also read the dimensions on&nbsp;your old glasses. The size is usually written on the temple arm.&nbsp;</p> <ul> <li>54 stands for Lens Width, which&nbsp;is the horizontal width (in millimetres) of each lens.</li> <li>18 stands for&nbsp;Bridge Distance, which is the distance (in millimetres) between your two lenses.</li> <li>140 stands for&nbsp;Temple Length, which is the length (in millimetres) from each screw to its temple tip.</li> </ul> <p><img alt="" src="https://df5apg8r0m634.cloudfront.net/email/2019/1225/kGOO4K83HLFJJ41i.jpg" /><br /> &nbsp;</p> <p>3. Try on glasses at a local optical store and note the size that fits you. Then find a similar size on our website.<br /> &nbsp;</p> <p>4. We divide our frames into 3 categories: Narrow, Medium and Wide, which represents the total width of the frame. The sizes for each category are listed below.</p> <p><strong>Narrow:</strong>&nbsp;Total Width&nbsp;&lt;129mm</p> <p><strong>Medium:&nbsp;</strong>&nbsp;Total Width 129mm to 135mm</p> <p><strong>Wide: </strong>Total Width&nbsp;&gt; 135mm</p> <p>You can use these sizes to filter results when searching for frames.<br /> <img alt="" src="https://df5apg8r0m634.cloudfront.net/email/2020/0519/fsxerpajqF6a9Fzf.png" /></p>
