Optical capture rate — the share of patients with a new prescription who buy their eyewear from you — is the most consequential number most optometry practices don't track. The gap between a mediocre capture rate and a strong one, across a year of exams, often exceeds the profit of the entire exam schedule. And the levers that move it are surprisingly unglamorous: a handoff, a presentation, and a follow-up call almost nobody makes.
First, measure it honestly
Count prescriptions written, count jobs sold, divide. Include the walkouts, the "I'll think about it"s, and the patients who took the Rx to a chain or website — that's the point of the number. Most practices guessing "seventy percent" measure and find something meaningfully lower. The gap is the project.
The handoff: where capture is won or lost
The single highest-leverage moment is the transition from exam lane to optical. The failing version: doctor finishes, patient collects their Rx at checkout, drifts past the frame board, leaves. The working version: the doctor personally walks the patient to a named optician — "Maria's going to take care of you; I've told her what I recommend for these new progressives" — converting a retail browse into a clinical continuation. The prescription becomes a treatment plan with a person attached. Practices that install the doctor-handoff as an unskippable ritual watch capture move within a month, at zero cost.
The presentation: sell the seeing, not the SKU
Eyewear presentations fail when they start with price tiers and lens-option matrices. They work when they start with the patient's day: what they do, where they struggle, what the doctor found. The optician who says "with your screen hours, here's what the doctor recommended and why" is practicing translated medicine — our optician guide calls this the craft's core — and premium-lens acceptance follows clinical framing far more readily than discount framing. Second-pair conversations belong here too, anchored to real use cases (sun, sport, screen) rather than a percentage-off coupon.
The follow-up: the rescue system nobody runs
Here's the leak almost every practice ignores: the patient who left with an unfilled prescription. They weren't a no; they were a not-yet — and within thirty days they become someone else's customer. The fix is a simple outreach rhythm: pull the unfilled-Rx list weekly, and make the calls — friendly, service-framed ("Dr. Lee wanted to make sure you'd taken care of those new lenses — want me to have your numbers ready?"). Add benefit-expiration timing ("your frame allowance resets in December") and the call gets even easier to receive.
Notice the operational shape of this system: a weekly list, daily calls, consistent scripts — exactly the portable desk work that dies at a busy dispensary and thrives with a dedicated owner. It's why capture-rate follow-up sits naturally in a remote assistant's portfolio alongside recall and reorder outreach (both covered in their own guides): the optician stays at the board doing the irreplaceable in-person craft; the remote teammate runs the rescue list that keeps the board's pipeline full.
The scoreboard
Track four numbers monthly: capture rate overall, capture by doctor (handoff discipline varies — the number will say so diplomatically), premium-lens mix, and unfilled-Rx recovery rate. Set a quarterly target of five points of capture improvement; between the handoff ritual, the clinical presentation, and a follow-up list that finally has an owner, most practices find five points embarrassingly reachable — and worth more than any marketing campaign they ran last year.
