"Opticianry is ultimately defined by how well the eyewear makes
contact with the patient, not by the number of customers served.
Therefore, a conscious, precise, and personalized process of frame
selection, lens design, and in-place, hands-on fitting is required. In too
many cases obsessive and unrealistic sales goals override the optician's
mission of providing good professional health care, whereby the personalized,
custom-fitting of prescription eyewear is given only minor consideration, if any."

"The customized fitting of eyewear involves more than just adjusting a nose
piece or bending a temple. It has to include the reshaping, bending, stretching,
twisting and artful sculpting of the frame components in order to personalize the
eyewear. Anything less will most likely compromise the patient's visual comfort
and long term wear-ability. The difference between adjusting and customizing is
what's different between today's eyewear merchants and yesterday's opticians."

"Just as a dentist cannot practice dentistry without direct patient contact, the
optician cannot effectively dispense without tactile contact with the patient.
An unskilled eyewear merchant routinely hands over prescription glasses
with no hands-on assessment, nor the appropriate ‘touch-and-feel’ required
to custom-fit the eyewear. When skilled opticians dispense however, they de-
termine for themselves how the frame feels in addition to asking the patient." --
