Deciphering eye glass prescription

May 14, 2013 7:03 PM

I need new frames. I'll be getting them online. I'm pretty sure I have the pupillary distance on my prescription, but I'm not sure which number it is. On the add section, there are two numbers: 61.5 under distance and 58.5 under near. From my googgling, I assume there are two numbers because I have a monocular PD. Is that correct? Also that i should use the distance number as my PD. Am I correct in that assumption? One more thing, all the examples of PD I've seen are whole numbers, so do I round up? Or just leave the number as is? Hope this wasn't to confusing.I can post a picture of the prescription if necessary. Thanks in advance!

Best answer: There are different numbers because your eyes cross a little bit when focusing on near objects. Use the distance number for everything except reading glasses. Bifocals will require both numbers.

A picture of the prescription would be helpful.

Best answer: You can round up or down your pd, that is not going to make a difference. Pjern has it right for which number to use when.

Response by poster: So here is the prescription if it helps influence the answers, and anyone is still checking this question out. I would have posted this last night, but life got in the way.
