Which is right for your practice?

These two products overlap more than most pairings on this site — both are software-only, both randomize letters, both cover the core clinical charts. The decision usually comes down to your practice's shape:

Solo practice weighing annual cost. On subscription terms the arithmetic is on record above: AcuityMaster Cloud is $249/seat/year against 20/20's published $49/month (about $588/year). If you strongly prefer a one-time purchase, 20/20's $1,749 full license may pencil out over enough years — and AcuityMaster has a perpetual answer too: the Legacy Windows edition at $1,300 per initial workstation (supported through December 31, 2026, as the platform transitions to Cloud). Run the math over your own planning horizon rather than taking either vendor's framing; our why-us page lays out the cost comparison in more depth.

Research-oriented or subspecialty clinic. Based on its published information, 20/20 positions its range as extending to more complex diagnostic tests for clinical research, which may serve that need well. AcuityMaster's research-relevant core is ETDRS/LogMAR — the clinical-trial standard, five letters per row with LogMAR scoring — rendered to ANSI Z80.21 / ISO 8596 calibration, alongside contrast sensitivity and Worth 4-Dot. Match the specific protocols you run against each feature list before deciding.

Mac or iPad practice. AcuityMaster Cloud runs in any modern browser on Mac, Windows, and iPad with nothing to install — see Mac eye chart software. As with any comparison, verify a vendor's current platform support against the computers already in your lanes; the requirements page covers ours.

Multi-lane or multi-location group. Per-seat pricing changes character at scale: AcuityMaster's volume tiers step down automatically to $99/seat/year at 50+ seats, with centralized administration across locations. A ten-lane group is not paying ten single-seat prices — worth modeling before comparing against any per-license alternative.

Switching or getting started

The cheapest way to settle a close comparison is to run one side live. AcuityMaster's 15-day free trial is fully functional — every chart and optotype, no credit card — so two weeks of real patients will tell you more than any table. If it fits, plans start at $249/seat/year.
