Not happy that I lost my sunglasses!

Sometime between dinner at Les Zygomytes and the walk back to the parking garage after “Wicked,” your friendly blogger lost his sunglasses. Yes, I wear sunglasses at night. Anyway, the research and replacement process took place today. This post may help you, and it will be my reference for next time…

If you’ve ever purchased prescription glasses, you know there’s quite a bit of measuring that goes on just above your nose. What’s being measured there is “Pupillary Distance” (PD), the distance in millimeters between your pupils. If you are buying progressive lenses to compensate for near and far-sightedness, you’ll also need the “Near” PD because the pupillary distance shortens (like going crosseyed) when you’re looking at something close to you like a book.

Anyway, my PD measurements were not on my prescription, but I measured it using a nifty online tool.  Once I had the PD (63), I used an optometrist community to learn that 94-95% of your PD will be your “Near PD,” depending on the size of your head. I went with “bulbous” and used the 94% calculation (59). With my prescription and fresh PD numbers I was able to easily order new peeps from (there are others) with a 25% off coupon I found here.
