How to take a pupil distance (PD) measurement

Knowing your pupil distance measurement will help us ensure that your lenses are fitted into the frame in the correct position. In order for you to experience maximum visual acuity we need to be able to position the centre of each prescription lens directly in front of your pupils. Some Opticians will gladly give you this measurement if you request it but many will refuse as they don't want their customers saving money and buying glasses on the internet. If, however the Opticians you visit has it's own website then you can always be a little cheeky and tell them that you want the measurement so you can buy from their website.

If you are unfortunate to be confronted by a stubborn Optician who refuses to hand over this information then you can easily obtain it yourself with the use of a mirror and a measuring rule. Here's how to take you own PD measurement:

1. Stand directly in front of a non magnified mirror at a distance of around 7 inches

 2. Take your measuring rule and place it just above your lower eye lids. Or, if you prefer, you can place it on your forehead just above your upper lids.

 3. Close your right eye.

 4. Align the Zero mark on the ruler directly in the middle of your left eye pupil.

 5. Now close your left eye and open your right one.

 6. Look directly into the mirror and check which number on the ruler is in line with the centre of your pupil. This is your PD measurement!

You can repeat this process a couple of times just to ensure that you get a consistant result. Most mens pupil distance measurements are between 60mm to 65mm, for most women it is usually between 58mm to 63mm.
