How To Measure Pupillary Distance
Your optician may or may not give you the PD (the optician is also not required to do so as part of your eye test)
Alternatively, you may
- Use an average PD, which is provided for you by our optician on the order form
- measure your own PD, you can do so by taking the following steps:
- Place the millimeter ruler on the bridge of your nose and focus on a fixed point in the distance e.g. widow frame at the end of the room
- Whilst you are looking in the distance, with a ruler your friend measures the distance between the centres of one pupil to the centre of the other in millimetres. (Average adult PD is normally between 60 and 65mm)
- When difficulty is experienced in determining the centre of the pupil, the edge of the iris (coloured part of the eye) may be used as a measuring point. Measurement is read from the left side of one iris to the left side of the the other iris
- Or you can do it yourself simply by looking in the mirror.
