Q: How do I calculate my pd for my order

A: It is always highly recommended that you get your PD measured by a professional. But it is also practical to measure by yourselves. Here is an article on it. https://leoptique.com/faq-prescription

Q: I have my rx for glasses but under the pd I have two sets of numbers. They are 32/35 and then 31/33. Which is the correct pd

A: You have a dual PD. Normally in a prescription, there could be two (sets of) PD values, one is for distance use glasses, the other is for reading or for seeing things up to close. The former is bigger than the later. But it is always highly recommended that you check with your optometrist for how to use those PDs.
