Glasses - PD - Pupillary Distance - any opticians or the like on here?

[mrsrobin]

I would like to buy some glasses online - I had my eyes tested recently but the PD is not on the prescription as I think they don't like to give it to you unless you buy your glasses there.
I usually have my old glasses reglazed and just post them (thus I think they can get the PD from my old lenses) but this time I want new frames.
So - does anyone know how exact the PD has to be - as I have measured it on all the apps I can find and they are not the same. A couple of mm different. Does it matter if I take an average of all these? For info my prescription is very low.
Thanks in advance!

Whether the optometrist is any good or does not change the procedures that are required in an eye examination by the GOC/Optician’s Act.

I know when I got a new pair of glasses from Boots they put a sticker measuring gauge or something on the store pair. I presume that was to get my PD.

I'm sorry that's utter rubbish. It's a dispensing measurement and would be done in combination with a frame adjustment and heights for many lenses so ensure you're looking through the optical centre of the lens.

I've been an optometrist for many many years, have trainees, a master's and several additional qualifications and neither I, nor any of the my colleagues would take a PD in the test room.

Its definitely easier when someone else measures your PD, that said, a lot of people do measure their own PD successfully at home now especially with lower prescriptions where a small difference won’t usually affect things too much.

The main thing is consistency. If you’re getting wildly different numbers then it’s worth getting it done professionally, but if your measurements are coming out very similar each time, that’s usually a good sign you’re in the right range. Sometimes an independent optician can measure you PD for a small fee (£5-£10) which is worth it if your saving in the long run.

websites like Sapphire Optics, glasses direct, etc usually have a guide on how to measure your PD at home.

Thanks for that - just in case anyone might find this useful - I sent my glasses to an online opticians for reglazing - they took the PD from the previous lenses. This did match what I had averaged from my DIY PD measurements (I requested the reading from them for future info). My glasses are a low prescription.
