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 starts at $249 a year for the first seat (lower graduated rates above) 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 — AcuityMaster Cloud is subscription-only, so if owning the software outright is a firm requirement, that is a fair reason to choose differently. 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 the ANSI Z80.21 / ISO 8596 designs, alongside reduced-contrast acuity 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 and iPad 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 rates are graduated, so each further band of seats costs less — a ten-seat group pays $1,280 a year, an effective $128 per seat — 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 free trial is fully functional — every chart and optotype, no credit card — so a week of real patients will tell you more than any table. If it fits, plans start at $249 for the first seat.

Common questions

Does AcuityMaster support randomized letters?
Yes. AcuityMaster randomizes letter presentation to prevent patients from memorizing the chart between visits.
