The Power and Politics Of The PD, Part Four of Four

By Barry Santini, ABOM
Monday, January 2, 2017 11:10 AM If we look at the dynamics of oversight for prescription eyewear worldwide, we note how the regulatory atmosphere is changing with the arrival of online prescription eyewear. For example, in 2010, the Canadian Health Minister in British Colombia, responding to a court case involving a prominent online optical retailer, was prompted to review the current regulations concerning eyeglasses contained in the applicable Canada's Health Professionals Act.

Monday, December 12, 2016 12:15 PM The sale of eyeglasses has been the single greatest revenue generator for optical stores. But you can't begin the sale of glasses without first having an Rx, and eye exams are financed in large part through participation in vision care plans (VCPs). For most consumers, the scheduling of exams and availability of eyewear allowances is set through the VCP’s logistics.

Probably no question elicits more surprise and emotion from eye care professionals than when they're asked: “Can I have a copy of my Rx and PD?” Why? Because this innocent request is really an arrow aimed straight at the heart of historical "control" ECPs have had over the sale of prescription eyewear. If we step back and take a longer perspective, we can see that this is just the latest manifestation of a consumer empowerment process that began more than three decades ago.

In traditional progressive lenses, the designer defines a series of performance goals, including a target corridor length and reading add, fixed lens areas, along with a merit weighting of various optical errors, and then enters into an iterative process to figure out which elements of progressive surface should be manipulated to achieve these goals.

Monday, October 31, 2016 10:10 AM To begin the choice of a corridor length, start with your fitting height, and subtract 4mm to 5 mm, which allocates enough height for a minimum useful reading area. The difference left is a good approximate number to begin determining your target corridor length.

It's Jetsons!

Technology-driven change has been impacting the optical field for years. From smartphone auto refractors to Optos imaging, it's "out with the old and in with the new!" But despite the onward march of new tech, the ins and outs of choosing and fitting frames has hardly been impacted at all. Sure, virtual try on (VTO) frame technology popped up...but it also popped back. It seemed safe to say that the gold standard of in-person try on, consultation and frame fitting would never be surpassed.

Monday, November 9, 2015 10:05 AM With many variables to sort through in investigating a vision complaint, anything that could help to reduce the pool of possible suspects should be welcomed with open arms.

Ask just about any eye care professional when knowing the fitting vertex distance of a pair of glasses is important, and they'll no doubt respond: "For powers over 6 diopters, you'll have to compensate the power for the difference between the exam vertex distance and the wearing vertex distance."​

Monday, October 26, 2015 10:00 AM For most of the last century, eyeglasses were fabricated using a binocular measurement for pupillary distance, and simply dividing it in half to center the lenses for each eye. This method delivered apparently great patient satisfaction, as visual complaints were not clearly traceable to the lack of using a "proper" monocular PD....even for segmented multifocals.

What’s Causing The Increase In Myopia? Here the experts rarely all agree, Most feel that parental genetics are important in determining whether any individual becomes myopic, but in view of the worldwide increase in myopia, researchers often place genetics behind these common suspects...

Wednesday, August 19, 2015 2:00 PM Within the last 20 years, both the prevalence of myopia and its rate of increase within the world’s population are rising. It is estimated that 33 percent of the U.S. population is myopic (defined as greater than -0.50D) and can range up to 80 percent in some Asian countries like Singapore and Taiwan.

Service Fees or Service Free? Part 2

Monday, December 16, 2013 2:00 PM There's a message here: If you want add a new revenue stream to your practice while gaining access to a much larger client pool than you might ever sell to directly, you need to start implementing service fees that are logical and elicit positive emotional responses, and are perceived as being reasonable.
