Does anyone have experience with this machine here, or those similiar? I've just received one this past Friday and can not for the life of me get a correct PD out of it. While it is fairly ACCURATE, it is accurately in-correct. I am consistently getting 1-1.5mm wide on the binocular PD with it. I've already been explained by Essilor about this magic box that knows how to convert near to distant PD and that the monocular measurement will not match against a reflex pupilometer, however the binocular measurement should be comparable even according to them. Has anyone else experienced this issue with digital stand-alone measuring devices like these?
