Here at Bailey Nelson we care about your peepers, after all you need them to see all the awesome things you do everyday. To ensure we get your prescription sitting perfectly in your lenses we need something called a Pupillary Distance Measurement (or PD for short). We know it’s a mouthful but keep reading and you will get your head around it in no time. Pop in to a Bailey Nelson store to have your PD measured, or if you're ordering online you can use our nifty online tool to measure your PD during checkout.
Whilst the distance between your pupils is one length, you'll have to halve it to work out the PD for each eye, e.g. if your PD is 60mm, your left and right eyes will be 30mm each.
If you can't halve your PD to a round number, no problem - split them to the closest 0.5mm, e.g. if your PD is 60.5mm, fill in: right = 30mm, left = 30.5mm. We see this quite a bit so, don't worry, we know how to deal with it.
The average PD is somewhere between 59-68mm. If yours falls outside this, or you have a prescription over +/-6SPH, get in touch with us and we'll give you a helping hand.
