  1. Understanding Your Prescription?

    Your prescription must be no older than two years. Your recommended intervals between eye tests vary depending on your age and health – find out more about this in Your Eye Test.

  2. Pupillary Distance

    What Is PD or Pupillary Distance
    PD measures the distance between the pupils of your eyes.  This measurement is important to make sure that your eyes match up to the optical centre of your lenses. The average adult’s PD is around 63 mm. Armed with your prescription and PD, you can shop on to find your perfect pair. Your PD measurement is typically written beneath the prescription.

    How can PD be measured?
    PD can be measured in two ways. The first is binocular, which is a pupil-to-pupil measurement and involves a single measurement, like 63 mm. The other type of measurement is called monocular, which is a per-eye measurement from the pupil to the middle of the face. It is a double value measurement, like 31mm/31mm. Monocular measurements are most often used when the face is not perfectly symmetrical, meaning one eye is closer or farther from the middle of the face than the other.

    I don’t know my PD
    If you’re unsure of your PD and don’t have a spare pair of glasses to send us to get a PD measurement from, you can simply choose the “Use Average /I don’t know my PD” option and we will use an average value of 63mm. If you have a higher prescription, we recommend you seek your correct PD value before placing your order.

    How do I measure my PD at home?
    Measuring your own PD is easy – simply buy a PD ruler from our store then follow the video guide below!
