    I was told that we should keep using an existing PD even it it is slightly off because a person's brain gets use to it and it would be more of an issue for them to have to readjust if it is not that...

    PD on RX?

    Along those lines I'm wondering something and I've seen two large shops with opposite takes on this--If the Rx has the PD on it is it ok for the Optician to retake the PD anyway? Occasionally I've...
