It's a small effect, but it is noticable.

Your PD isn’t part of the prescription. But the prescription itself must be provided to you by law in the US.
For anyone near a Warby Parker, they'll happily measure your PD in about 30 seconds. Measurements can vary slightly so you might want to do it a few times and average them.
Maybe the failure rate is low enough that it is not worth it to improve the process...
The best eye "hack" I've done is getting Lasik. I wore glasses and then contacts for about 20 years and got Lasik done 3 years ago. It's worth whatever it costs you.

> she’s not happy to share the measurements with me as she fears I’ll run off and get my glasses made online (I’d never do that!). This is ridiculous. Why should I not be given the value measurements that have just been made? That's why I bought my own optician test lens set and now do the measurements myself.

That's cause PD is measured by the optician separately when you're ordering your glasses, not by the optometrist or opthalmologist who writes the prescription. In other words, it's not part of the prescription, it's instead part of the glasses fitting process. A non-eye related example would be if your doctor prescribed you a brace and the person at the medical supply store measured you to find out which size you nee…
