Do you need pupillary distance for my prescription Swannies?

Yes, we will need your pupillary distance but if you do not have it, you can follow the below instructions, or you can send us a photo like this the one attached, with standard sized card, and will work it out for you.

1. Wear your glasses. (Or any glasses if you don't have your own. Even just try on demo glasses at the mall if you are that bold.)
2. Have a felt-tip non-permanent marker handy.
3. Focus on a single object in the far distance (anything farther than 20 feet works, but farther is better).
4. Raise the marker to your right lens and precisely put a dot on it directly over the distant object.
5. Repeat for your left eye. If done correctly, with both eyes open the two dots should overlap into a single dot over the distant object. If not repeat making the markings until they do form a single dot.
6.  Measure the distance between the two dots on your lenses with a millimeter ruler.
7. That's your distance PD.
8. If you need a near PD for reading or computer glasses, just do the same procedure but focus instead on the object you will be looking at, either reading material or computer monitor.
