IIRC, my dad bought progressives from Zenni and said they were as good as the ones he got from an optician.
I mean, they need to measure where your eyeball lands on the glass when looking straight ahead. This isn't part of the prescription, from what I understand. Usually, a salesperson will do the measuring. In light of this, do you have any further information as to how your father obtained that information and how he provided it to the online store?
Do you mean pupillary distance? It isn’t part of the written prescription when I get my exam, but if you ask they usually don’t have a problem giving it to you. When you’re ordering Zenni just has a field where you enter the number they give you for PD. They also have instructions for DIY PD measuring, but that seemed too error-prone to me.
No, it isn't PD.
