apples and oranges (seems to be your modus operandi). If its not crappy burgers at arbys, its tuxedo measurements
. I see the fitting of eyeglasses with their corresponding biometrics to be part of the service of the optical. PD alone is hardly sufficient to fit many spectacles, and I find it misleading to suggest otherwise. You know as well as I do that without a seg height the specs are destined to be a problem and your only defense is a meager attempt to preserve goodwill. I think when the specs arrive and they are a problem, that you are at more risk of flushing that goodwill down the toilet. Having experienced this firsthand I can attest to this risk. Few years ago, pt wanted a pair of sunglass specs from Orvis, and I provided the PD measurement and of course he ended up having problems. Orvis suggested that the PD I provided was wrong. Total crock of course and after measuring their specs I found the power was off in one eye by almost a diopter.
