Which is right for your practice?
Feature lists only get you so far — the more useful question is what your practice actually looks like. A few common profiles, and an honest read of each:
Solo optometrist keeping costs predictable. If you run one or two lanes, AcuityMaster Cloud is $249/seat/year and runs in the browser on the computer already in your exam lane, so there is no new hardware line-item and no long-term commitment beyond the annual seat. That said, if you have already licensed Spectrum, it runs reliably on your current setup, and its chart library covers the tests you use every day, there may be no pressing reason to switch.
Mac-based practice. AcuityMaster Cloud was built to be platform-agnostic — it runs in Safari, Chrome, or Edge on Mac, Windows, and iPad. If your lanes run Macs, or you want the option to drive a chart from an iPad, see our Mac eye chart software page. Whatever you choose, confirm any vendor's supported operating systems against your actual hardware before committing.
Multi-lane group standardizing across rooms. Volume pricing steps down automatically to $99/seat/year at 50+ seats, and every lane presents the same distance-calibrated charts, which makes room-to-room standardization straightforward. Based on its published information, Spectrum bundles ocular disease management and patient education tools alongside its charts — if you want those functions in one package, that may appeal; if you handle patient education elsewhere and want the acuity lane itself standardized, a focused tool is simpler to roll out.
Practice that prizes sheer chart variety. Spectrum's advertised 200+ chart library is a genuine strength, and if breadth of chart options is your deciding criterion it may serve you well. AcuityMaster's argument is depth over breadth: the tests clinicians reach for daily — Snellen, ETDRS/LogMAR, color vision, contrast sensitivity, Worth 4-Dot, and pediatric optotypes — rendered to ANSI Z80.21 / ISO 8596 calibration at your exact lane distance. The full list is on our features page.
Switching or getting started
Because AcuityMaster Cloud is browser-based, evaluating it costs nothing but a bookmark. Check the system requirements, start the 15-day fully functional free trial — no credit card — and run it side by side with your current chart software for two weeks of real patients. If it earns its place in the lane, plans start at $249/seat/year; if not, there is nothing to uninstall.

Does AcuityMaster include a free trial?

Can I evaluate AcuityMaster alongside my current chart software?
