How to take a PD photograph

Why do we need a PD photograph from you?

Your pupillary distance (PD) is the measurement between the centers of

your pupils. It's essential to ensure the lenses in your glasses are

properly aligned with your eyes. By providing a PD photograph, we can

accurately measure this distance, guaranteeing your glasses offer clear,

comfortable vision.

How to Take the Perfect PD Photograph

To obtain an accurate PD and height measurement for glazing your glasses, follow these steps when taking the photograph:

• Ask someone to assist you by taking a picture of you. You don't have to be wearing glasses for this.
• Place a millimetre ruler, tape measure, or debit card horizontally over the top of your eyebrows. This reference object will serve as a scale for measurement.
• Look directly into the back camera lens.
• For optimal results, the photographer should position themselves at least 6 feet away from you and then zoom in to capture a clear and focused image of your eyes, particularly your pupils.
• Adequate lighting is crucial, so if possible, take the picture in a well-lit area or outdoors. Avoid using the flash as it may cause glare on the lenses, obstructing a clear view of your pupils.

Alternatively, you can use the GlassesOn app to easily measure your PD. This app uses advanced technology to accurately measure your pupillary distance from the comfort of your home. The app is available on Google Play and the Apple Store.

Why can’t I take the picture myself?

Taking a selfie or even setting up a timer and taking it yourself will not

work. The front camera of most devices can introduce distortions in the

image, making it challenging to obtain precise measurements. The same

issue applies when using webcams for this purpose.

I’ve taken the picture, what do i do now?

Now you have had your PD picture taken and you are happy with it,

you can send it over to us to obtain your PD measurement. To do

this you can email it over to us at info@spex4less.com along with a

picture of your prescription.
