>It's easy enough to measure myself
Do you have any recommendations about this? It's the kind of thing I'm a bit nervous about searching as I can see many, many ways I might accidentally read the optician equivalent of an anti-vaccination blog.
- Johnny555 10y agoHere's a guide from one of the online glasses sellers: http://www.zennioptical.com/measuring-pd-infographic http://www.zennioptical.com/measuring-pd-infographic They sent me a free PD ruler (it has a slit in the middle so you can see your pupils and a notch in the middle to center it on your nose) with my glasses, but I just used a standard ruler the first time I measured, and got the same measurement when my glasses arrived and I used their ruler. I was off by 1 mm in one eye when I compared to my eye doctor's measurements. For my prescription, that's not very significant, but it might be for a stronger prescription. You can buy a PD ruler for a dollar or two from eBay if you don't want to use a standard ruler.
