Which is right for your practice?

Free software and paid software both have a rightful place in eye care — which one belongs in your lane depends on who you test and what you need to rely on. Four common profiles:

Cost-conscious practice trying digital charts for the first time. If you are moving off a projector and simply want to see whether a screen-based chart fits your workflow, ForeSight's free editions — it publishes several tiers — are a low-risk way to find out, and for basic daily acuity checks they may serve you fine. The questions to ask before settling in long-term are the ones our digital eye chart software guide covers: calibration, platform, updates, and support.

Pediatric-heavy clinic. This is where AcuityMaster makes its strongest case. It includes HOTV, Tumbling E, Landolt C, and picture optotypes, plus crowding bars for amblyopia assessment and video fixation targets for patients too young to play along — all listed on the features page. If a meaningful share of your schedule is under age seven, test any candidate software against that population during a trial before you commit.

Mac-based practice. AcuityMaster Cloud runs in any modern browser on Mac, Windows, and iPad, with nothing to install — see our Mac eye chart software and iPad eye chart software page. Whichever product you evaluate, confirm its supported platforms against the computers actually in your lanes.

Group standardizing across rooms or locations. When several technicians test in several rooms, consistency is the clinical asset: AcuityMaster calibrates every lane to ANSI Z80.21 / ISO 8596 from the entered distance, and volume pricing is graduated, so each further band of seats is charged at a lower rate. Free software can be harder to standardize and support at that scale, though your IT resources may change that calculus.

Switching or getting started

The fairest comparison is a live one. AcuityMaster's free trial is fully functional — every chart and optotype, no credit card — so you can run it head-to-head with ForeSight on your own patients over the seven-day trial. ForeSight is free and does not expire, so there is no rush on that side of the comparison. If the paid tool earns the difference, plans start at $249 for the first seat/year (graduated); if not, you have lost nothing.

Common questions

Does AcuityMaster run on Mac?
Yes — AcuityMaster Cloud runs on macOS and Windows in any modern browser.

What standards is AcuityMaster designed to?
AcuityMaster is designed to ANSI Z80.21 luminance and ISO 8596 optotype requirements, with optotypes calculated from the testing distance you enter. Both standards also constrain luminance and contrast, which are properties of your own monitor — verify against your display if conformance matters in your setting.

Does AcuityMaster include pediatric optotypes?
Yes — HOTV, Tumbling E, Landolt C, and picture optotypes, plus crowding bars for amblyopia assessment and video fixation targets.
