The question always arrives at the same moment. The exam went well, the prescription is fresh, and the patient is standing at the dispensing table with their coat already on. "Can I get a copy of my PD?"
Most practices treat that question as a customer-service problem. Answer it politely and move on to the next patient. Our founder has a harder read on it, and she said it out loud on a Techifeye webinar episode about optical technology.1
"If somebody asks you for their PD, you have already lost the sale. So don't sit in there and get another one-star review. Figure it out so it doesn't keep happening."
That reframe deserves a closer look, because it changes what the front of your practice should do about the most uncomfortable question in optical. Your optical capture rate is not decided at the moment of the ask. It was decided in the twenty minutes before it.
When a patient asks for their PD, they are telling you their decision is already made. They committed to buying somewhere else before they reached the dispensing table, and now they are collecting the parts they need to do it. Arguing at that moment, or charging a fee out of frustration, punishes the patient for a decision your process let happen.
Dr. Rhue's point is that the question is a signal worth logging, the same way you would log a remake or a no-show. One ask is a patient with a coupon. The same ask every day is a pattern.
Her diagnostic from the same episode applies to every corner of a practice. "If you hear the same thing over and over and over again, it means something is broken in the process. So you have to practice this language."
So the useful question is not "what do we say when they ask?" It is "what happened upstream that made them ask?"
Walk the patient's path backward from the dispensing table and the candidates show up quickly.
Sometimes the sale died on perceived value. The patient moved through a pre-test room full of instruments and an exam lane full of screens, then watched an optician reach for a marker and a plastic ruler. The licensed opticians Dr. Rhue interviewed on that episode were blunt about this: the measurement tools many practices still use were designed for the lenses of 80 years ago, and warehouse clubs now run measurement technology that used to be a private-practice differentiator. What once read as high-tech now reads as the floor.
Confusion kills it just as often. Vision plan math gets stacked on top of discount rules and lens jargon at exactly the moment the patient is trying to decide whether to trust you with a four-figure year of eye care. Dr. Rhue's example from the episode: patients routinely call progressives "transitions" and transitions "progressives," and nobody has explained high index or anti-glare in words that justify their price. The terminology that makes a practice sound expert is often the thing talking the patient out of the purchase. A patient who cannot follow the pricing logic defaults to the channel that feels simpler, even when it serves them worse.
The third culprit is attention. Dr. Rhue calls it "onto the next syndrome": the practice is so focused on moving to the next exam that nobody owns the handoff between the chair and the optical. She tracks the opposite behavior in her own South Florida practice, where a daily text reports how many patients were seen and how many complete pairs sold, alongside the day's collections. Twenty patients and five pairs sold is not a patient problem. It is a process number, and you cannot fix a number you never see.
If this pattern sounds familiar, it should. The optical version of "can I get my PD?" has a contact lens twin: "can I just get my prescription?"
We wrote about that moment in the 30-second script that keeps patients ordering with you, and the anatomy is identical. The patient has already decided to buy elsewhere, the staff treats the request as paperwork, and the practice loses a year of supply revenue in the time it takes to print a script. A large and rising share of contact lenses are already bought online, so the default outcome of an unmanaged handoff is not neutral.
The dropout math works the same way. When we dug into the dropout story most practices have wrong, the lesson was that patients rarely announce they are leaving. They send small signals, the signals repeat, and the practices that grow are the ones that treat repetition as a diagnosis.
Capture rate is the scoreboard for all of it. Dr. Rhue has been hearing the same thing from practice owners that we have: capture rates have been sliding noticeably as patients tighten up and shop around. The practices holding their numbers are not the ones with the best retail instincts. They are the ones that noticed which question kept repeating and fixed the step that produced it.
Here is the practical version, and it costs nothing to start.
For the next two weeks, count the asks. Every time a patient requests their PD, or their contact lens prescription with that "I'm leaving" energy, it goes on a tally with one note about where in the visit it happened. No scripts yet, no policy changes. Just the count.
Then bring the tally to a team meeting and ask the upstream question. Did these patients hear the value of our measurements before they asked? Was their vision plan ever translated into plain language? And did the doctor's recommendation survive the trip from the exam lane to the dispensing table?
The tally usually points at one step, and it is almost never the step the team expected. That is the step worth rebuilding, with language your staff has actually practiced out loud. Dr. Rhue's practice rebuilt theirs around a specific script for the PD conversation, including a calibrated handoff question that gets patients to sit back down. The thinking behind that kind of question is the same pattern we covered in "if I may ask, in the past...", and it works because it lowers defenses instead of raising them.
The instinct when a patient asks to walk is to win that moment. Better language helps, and we will keep sharing the scripts that work. But the practices that actually move their capture rate treat the ask as a free audit. Somewhere between the pre-test room and the dispensing table, the patient decided you were a place to get measured rather than a place to buy. The tally tells you where.
That is the same discipline we bring to the contact lens side of the practice every day: watch the repeated signal, then find and rebuild the broken step so the next patient never has a reason to ask. If you want to compare notes on what your patients keep asking and what it is telling you, we have that conversation with practices every week.
