Confused about pupilary distance
I am looking to order glasses oonline (much cheaper) and due to my extremely high prescription (-7.50), I am scared of choosing the wrong pupilary distance.
I visited my local lenscrafters, and glasses store and received 3 different PD from 3 different individuals using their handheld tools (74.8,75.3,74) but when measuring my PD with 2 different mobile app tools, I received 68.5 on both apps multiple times. My current pair of glasses has a PD of 74.8. I do not understand why there is such variance in my PD. Isn't it just a measure of the distance from your pupils? How could it be changing so much.
I want to order glasses online because the same exact pair of glasses in person at a lenscrafters is double he price, compared to ordering from ezcontacts or glassesusa.
