At vision expo west, I was manning a both as a live testimonial for a company that sells dispensing
systems with digital centration. I guy comes up and asks can you Use this system to measure glasses online. So, I tell him no, in conversation he tells me he has a couple of stores and an online optical
Site. He tells me when he sells glasses online he gives everyone a standard pd for the frame size and make all the heights for progressive lenses 4 above. Although he only gets a small
percentage back he feels most see well enough using standard default calculation. I strongly disagreed but was not going to try and argue with him and I let him move on. A few minutes later a women
comes by and looks at the system and tells me that she only sells digital lenses and proclaims that
she feels her customers only want the best products available. I then explain to her that if she is
giving digital lenses and not taking the additional measurements ( face form, rear vertex distance, and panto angle ) than they are really not getting true personallized lenses. Your lab is just using default
calculations and only when those default calculation coincidently mirror the patients real values,does
that patient really get there value when ordering Personalized lenses. I then explained the story
above and the similarities in using default values, she then purchased the system.
