Prescription glasses online, made easier
Pupillary distance is one of the measurements we use to correctly centre your prescription lenses. If it's not on your prescription, you can easily measure it during the lens selection process.
What PD is
PD, or pupillary distance, is the distance between the centres of your pupils. It helps us position the optical centre of each lens correctly in front of your eyes.
Because correct centring helps ensure your prescription lines up with your gaze and delivers comfortable, precise vision. For Oakley lenses, the brand's own technical documentation also states that centring must follow interpupillary distance and fitting height.
Built-in digital measurement
Inside the lens configuration process you'll find a pupillary distance measuring tool. The app uses your camera to guide you step by step and get the measurement we need to prepare your lenses.
Follow the on-screen instructions.
Before you measure
The reference we follow favours visual, simple, step-by-step instructions. We've taken the same approach here to reduce any doubts before you open the tool.
Stand in a well-lit area and, if possible, in front of a plain background. This helps the camera see your face more clearly.
Hold the device facing you and centre your face. Avoid tilting your head or looking to one side during the capture.
The tool may ask for a card similar in size to a bank card as a scale reference. Follow the on-screen instructions exactly and don't show any sensitive information.

No problem. During the lens process you'll have an app available to measure it by following the camera's instructions.
We don't treat measuring as a separate step: the tool is built directly into the lens selection process. When you reach the relevant step, you can use it if you need to get your PD.
Yes. If your optician has already given you your pupillary distance, use the value shown on your prescription or professional measurement.
Yes. Centring is especially important when a lens needs to position different vision zones relative to your eyes. Always follow the measurement fields requested during configuration.
