Hi Smith, Those are your individual PD's for each eye. Most people's faces aren't exactly symmetrical - so this means that your left pupil is one millimeter further from the bridge of your nose than your right pupil.
When ordering online, let them know that you have separate PD's and they'll be able to manufacture them properly. EyeBuyDirect lets you enter the two separate PD numbers right on their order form. I'm not sure about other sites, but many have an area for comments where you can let them know. Just say "I have separate PD's. R: 31.5, L: 32.5". For the ADD, you don't need that number unless you're ordering bifocals / progressives. It refers to the magnification of the reading area. Hope this helps!
