AcuityMaster - 2026 Pricing, Features, Reviews & Alternatives

AcuityMaster Cloud is a browser-native visual acuity platform for ophthalmology and optometry. There is no client to install and no proprietary display hardware.

Platforms — Safari, Chrome, Firefox or Edge on macOS 12+, Windows 10/11 or iPadOS 16+. An iPad can act as the patient-facing chart itself or as the controller. A second monitor is supported by extending the desktop: the chart runs full-screen on the lane display while the control panel stays on the clinician's screen.

Chart set — Snellen (US, metric and decimal notation), etdrs/Logmar, color vision screening plates, reduced-contrast acuity at four contrast levels, Worth 4-Dot, fixation disparity, astigmatic dial, red-green duochrome, and pediatric optotypes: HOTV, Tumbling E, Landolt C and picture targets. Single-letter, single-line and multiline presentation, randomized between showings, plus crowding bars for amblyopia work and mirror mode for compact lanes.

Calibration — optotype sizes are computed from the patient-to-screen distance the clinician enters. Designed to ANSI Z80.21, which specifies a background luminance of 80–320 cd/m², and to ISO 8596. Not certified to either: luminance is a property of the practice's own display, which AcuityMaster does not supply or measure.

Security and data handling — AcuityMaster stores no patient data of any kind. No names, no dates of birth, no results. It is a display and testing system, not an EMR or EHR, and it contains no patient database. There is no protected health information to secure, transmit or breach, which is a materially different security posture from clinical record software.

Connectivity — sign-in and license validation require a connection. Once loaded, the chart display continues to work offline.

Licensing — annual subscription with graduated per-seat rates. A seat is one signed-in browser session rather than a registered machine, so hardware can be replaced without a license transfer. The first seat is $249 per year and each band above it costs less; ten seats total $1,280 a year. Automatic updates are included. A fully functional 7-day trial requires no credit card.
