I tried the method in the article and got a pair of sunglasses online from FramesDirect that were incorrectly made. I'm not convinced that it works.
My optician has a tool that measures my PD correctly every time. Unfortunately they are reluctant to give me the PD measurements for fear of losing my business.
So we meet half-way. I find frames online and I get the optician to put lenses in them.

It's your prescription. It's your health data. Don't take no for an answer. I'm almost positive that they are legally required to give you that data. Asserting your rights is not a bad thing.
To add to this, I get my prescription from the doctor, but I still buy glasses from them. They will open up on a Saturday for me. I've ordered what I consider to be disposable glasses online.

The $10 method to measure PD:

I failed and the glasses I ordered were unusable. In the end I brought them in to my optician's office where they precisely measured not only my PD but a couple of other metrics that I think described the frame/lens position on my face.
I sent all those measurements to the vendor (https://www.warbyparker.com) and the second glasses were perfect.
These other self-measure methods look better than the ruler-mirror method that I did, but if I ever buy glasses online again, I'm going to take the trial frames straight to the optician's for proper measurements.
