There you go again, this is simply not true. There is little point in sending you a pm if you are so arrogant as to believe that you know more about eye exams than an optician with 40 years experience.
incorrect pd's certainly do not have little or no effect in the vast majority of cases. I'll give you another example. a few years ago i got my dispensing optician to make me up a new pair of glasses. I wrote down my prescription for her but she misread by pd and they were made up with a pd that was out by 3mm. I do not have a big prescription. Within a day or two of wearing the glasses I knew something was not right because althought my vision was clear my eyes were strained and on checking the pd I discovered the problem.
Over my career I have preformed over 100,000 eye exams, how many have you preformed?
I could give you many many more examples but I would hope you would have the humility to accept that I might know more about this than you do!
