I once tried to measure my own pupillary distance using the ruler-mirror method.
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 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.
- wenc 9y agoI 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.

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.
