What Is Pupillary Distance (PD)?Updated 8 months ago

Pupillary Distance is the distance in millimeters between your pupils. This measurement helps us to find the correct optic center of your lens and is specific to your proportions. We will need one to accurately input your prescription, as an inaccurate measurement can result in blurry vision or double images.

You can find your PD by using our PD Measuring Tool. This tool is also available at checkout when you click "Need to Measure Your PD?".

You may also be able to contact your eye doctor to get your measurements from them.
