Your PD isn’t part of the prescription. But the prescription itself must be provided to you by law in the US.

#133Maybe the failure rate is low enough that it is not worth it to improve the process...

#134The 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.

#136> 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. I can also test these measurements over a long period of time looking at a screen for example. I've had peop…

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…
...and can be measured at home using a ruler and a mirror, pretty simply. Close one eye, align the ruler at 0 under that pupil. Open the other eye, close the first, read off the distance to the 2nd pupil.
