I am opposed to the proposal to require the release of the pupillary distance measurement as part of an  eyeglass prescription.  Although this is thought to be part of an eyeglass prescription, which is obtained as part of a comprehensive eye examination, it is in fact not the case.  This measurement is obtained by the optician while measuring the patient for the proper fitment of eyeglasses.  It has never been a part of the clinical aspect of an eye examination.  It is not required for any other reason but to fit eyeglasses, which is a separate service and requires time and attention to provide accuracy.  We never collect this data in the exam room or during ancillary testing.  If the patient is seen in a venue that does not provide eyeglass services, does not employ an optician, etc such as a hospital based environment, many ophthalmologist's offices and many specialty optometric practices, these providers will immediately be in non-compliance with the rule.  The need to obtain this measurement on every patient will cost time and therefore legitimately add to the cost of an examination.  It should remain where it belongs: in the purview of the optical for the specific purpose of selling eyeglasses.  There is no need to add to the economic burden of the general population seeking eyecare for the benefit of a select and small group of people who choose to purchase their eyewear online.
