The complexities of contact lens management—trial fittings, inventory, ordering, and shipping—coupled with competition with online retailers and "big box" stores for patient loyalty can make the category feel like more effort than it's worth.
The data says otherwise: contact lens revenue should average 16 to 18% of an optometry practice's gross revenue,1,2 making it one of the more consequential lines on a practice's balance sheet.
That premium holds up at the individual patient level, too. Led by investigators from the University of Manchester, the University of Waterloo's Centre for Ocular Research & Education, and Appalachian State University's economics department, a commissioned analysis of 4 years of operational data from 20 US eyecare practices found soft contact lens wearers generated meaningfully higher average annual profit than glasses-only patients.3
The breakdown:3
- $436 for spherical wearers
- $453 for toric
- $485 for multifocal
- $244 for single-vision glasses patients
- $376 for progressive glasses patients
The advantage held even after accounting for the higher service and product costs contact lens patients require, which the investigators attributed to more frequent exams, recurring purchases, and ancillary spending.3
Why data-driven management matters
A practice can look busy and still be underperforming in contact lenses. Staff can report commitment to the category and still be missing achievable revenue. Data removes that ambiguity.4,5 Tracking a defined set of key performance indicators (KPIs)—quantifiable, trackable metrics reassessed at regular intervals—allows a practice to compare itself against industry benchmarks and catch problems before they compound.4
Patient capture: from prescription to purchase
Roughly 30% of a practice's patients wear contact lenses full- or part-time, and about 16% of all contact lens fits should be new wearers.2 These patients are worth cultivating: they pay fitting and evaluation fees beyond the standard exam, return more reliably for annual exams, and frequently purchase both spectacles and contact lenses.2
Practices below these benchmarks should offer contact lenses proactively to candidates rather than waiting for patients to ask. Contact lens capture rate measures how many patients given a contact lens prescription actually purchase lenses from the practice—the KPI that reflects a practice's ability to close the sale.
Combining full- and part-time wearers, industry averages range from 60 to 80%.2,6 A related metric, the percentage of contact lens wearers who also purchase spectacles the same day as their exam, benchmarks at 25% across independent practices.2
Revenue per contact lens exam
Revenue per contact lens exam quantifies what each encounter generates: divide contact lens product sales (or product sales plus fitting fees) by the number of exams over a given period. Product sales alone average $152 per exam;2,7 sales plus fitting fees average $428.8
Fitting fees that reflect the actual clinical time and expertise involved, when paired with higher annual-supply conversion and adoption of newer, more frequently replaced modalities, move this number up.
Retention and the case for annual supply purchases
A high capture rate does not guarantee full category success unless the patient purchases an annual supply. Annual purchases keep revenue inside the practice rather than at outside retailers, support compliance with replacement schedules, and reduce the staff time spent processing repeated small orders throughout the year.9
Retention benchmarks are hard to pin to a single number because they depend on lens modality. Monthly-replacement lenses run around 60% annual-supply conversion and biweekly lenses around 25%.2 Meanwhile, despite growing in popularity, daily disposables convert to annual supply less often.2,9 A practice that fits mostly monthly lenses may therefore show a higher annual-supply rate than a daily-disposable-forward practice, even when the latter is more profitable overall.
The clinical side of retention is worth tracking alongside the financial side. A 2022 cohort study following 524 first-time contact lens wearers across 29 UK practices found a 74% wear retention rate at 12 months, with nearly half of all dropouts occurring within the first 60 days of wear.10
The leading causes were correctable at the chair: vision-related complaints accounted for 42% of dropouts, followed by discomfort (14%) and handling difficulty (15%).10 That timeline supports building a structured check-in during the first 2 months of wear—not waiting until the annual visit—to catch and correct these issues before the patient lapses.
Tracking sales by modality and brand
Tracking modality (monthly, biweekly, weekly, daily) and brand distribution surfaces prescribing patterns and growth opportunities. Patients left in older, heavily discounted lenses simply because they haven't complained represent a refitting opportunity.
Introducing them to materials or designs that may improve comfort, ocular health, and overall wear experience, not only leads to improved satisfaction, but also helps the practice compete with online retailers based on something other than price.
Global data on materials and designs fit in 2025 appear in Tables 1 and 2.6 Many practices exceed these averages when they prioritize upgraded materials and designs. Specialty lenses are a further source of both differentiated revenue and patient loyalty.11
Table 1: Lens material, percent of 2025 global fits.6
| Lens Material | Percentage of Fits |
|---|---|
| Silicone hydrogel | 66% |
| Hydrogel | 21% |
| GP | 10% |
| Hybrid | 2% |
Table 2: Lens design, percent of 2025 global fits.6
| Lens Material | Percentage of Fits |
|---|---|
| Soft spherical | 41% |
| Soft toric | 31% |
| Soft multifocal | 14% |
Worldwide, the contact lens market grew 4% year-over-year as of 2025.6 That figure also works as a practice-level benchmark: compare the percent change in a practice's own contact lens sales from one year to the next to assess growth against the market.
Controlling costs without compromising care
Profitability in contact lenses depends as much on cost control as on sales volume: cost of goods, write-offs, shipping fees, and staff efficiency all factor in. The median gross profit margin on soft lenses is 46%.2
Bulk ordering, maintained inventory, and buying-group membership can improve that margin on the practice's side of the transaction—none of which requires changing what's clinically appropriate for an individual patient.
Lens selection should stay driven by what fits and serves the patient; margin is a purchasing and fee-structure question, not a fitting-chair question. Fitting and evaluation fees should reflect the actual time, expertise, and follow-up care involved, so the practice isn't relying on product substitution to protect profitability.
Practice management software, exportable EHR reports, and distributor- or manufacturer-supplied ordering data all support this kind of tracking without adding administrative burden.11
Conclusion
Tracking practice data, defining specific KPIs, and comparing them against industry benchmarks leads to measurable improvements in contact lens profitability. Share the data with staff, set attainable and specific goals, and reassess frequently.
5 key takeaways
- Contact lens patients carry a measurable profitability advantage over glasses-only patients—the category earns proactive attention, not just passive fulfillment.
- Data-driven practice analysis identifies where that advantage is being left on the table.
- Contact lens capture rate and revenue per exam measure how effectively a practice converts prescriptions into sales.
- Annual supply conversion has both a financial and a clinical dimension—tracking retention alongside sales catches correctable dropout causes early.
- Cost control belongs on the purchasing and fee side of the practice, not in the fitting decision itself.
