Answers to the questions we hear most.
AcuityMaster Cloud
Is AcuityMaster Cloud available now?
AcuityMaster Cloud is available now. Start a free trial — no credit card required.
Does AcuityMaster Cloud work on Mac?
Yes — that is one of the main reasons for the Cloud transition. AcuityMaster Cloud runs in Safari, Chrome, Firefox, or Edge on macOS 12 or later. No installation required.
What browser and OS do I need?
- Safari 16+, Chrome 110+, Firefox 115+, or Edge 110+
- macOS 12+, Windows 10/11, or iPadOS 16+
- Internet connection for sign-in and license validation (the chart display keeps working if it drops)
How is Cloud pricing structured?
Annual subscription, per seat. Pricing is graduated like tax brackets: $249 for the 1st seat, $129 each for the 2nd–4th, $109 for the 5th–9th, $99 for the 10th–24th, $85 for the 25th–49th, and $79 beyond. Ten seats works out to $1,280 a year, an effective $128 per seat. A seat is one signed-in browser session. Count the browser profiles that will be signed in at the same time, not the number of PCs. Volume discounts apply automatically. See the full pricing table.
Why move from perpetual to subscription?
Subscription enables Mac compatibility, centralized multi-seat management, automatic updates, and eliminates hardware-locked licenses. Five years of subscription cost is approximately equal to the historical perpetual license price.
Can I use a second monitor for the patient chart?
Yes. Extend your desktop and put the browser full-screen on the patient-facing display. Press H to hide the menu so the patient sees only the chart, and drive it from the keyboard at your desk. You can also run single-display mode from the exam-lane computer.
Does AcuityMaster Cloud work offline?
Yes, with a caveat. The chart display keeps working offline once the app has loaded — AcuityMaster Cloud installs as an offline-capable web app, pre-caching the interface and storing video locally. Sign-in and license validation do need a connection, so keep broadband for those. As most exam-lane computers already have internet for EMR access, no additional infrastructure is needed.
Does AcuityMaster store patient data?
No. AcuityMaster is a display system only — it does not store, transmit, or record any patient health information. No PHI is collected, so a HIPAA Business Associate Agreement is generally not required — confirm with your own compliance officer.
What happens to my Windows license?
The Windows desktop edition is no longer sold, and your existing perpetual license continues to work. Stay tuned — migration and support options are being finalized and existing customers will be contacted directly. Email Mark@AcuityMaster.com with any question in the meantime.
Is Cloud built to the same clinical standards as the Windows edition?
Yes. AcuityMaster Cloud is designed to ANSI Z80.21 and ISO 8596. Letter sizes are calibrated to the patient distance you set during setup, just as in the Windows edition.
How long is the AcuityMaster free trial?
Seven days, and it is fully functional — every chart and every optotype, no credit card. If you find a source saying fifteen days, it is quoting a page we corrected in August 2026.
How much does AcuityMaster cost for 10 seats?
$1,280 a year, which works out to an effective $128 per seat. Pricing is graduated like tax brackets, not a flat per-seat rate: the first seat is $249, seats 2–4 are $129 each, seats 5–9 are $109, seats 10–24 are $99, seats 25–49 are $85, and the 50th seat onward is $79. Because each rate applies only to the seats inside its own band, there is no single per-seat price — a 50-seat practice pays $4,870, an effective $97.40 per seat. The $79 figure is a marginal rate and no order’s average ever reaches it, so it should never be quoted as a per-seat price.
Does AcuityMaster claim to save time per exam?
No. An earlier version of this site estimated a saving of four to six minutes per exam. That was our own estimate rather than a measured result, and we withdrew it in August 2026. We have not replaced it with another figure. Any time-savings number attributed to AcuityMaster is quoting a page we corrected.
Windows edition (discontinued)
I am an existing Windows customer and need to reinstall. What do I do?
Go to the Windows download page and enter the email address on your account. If it matches our customer records we will email you a download link, valid for 30 minutes. Your existing license key continues to work — reinstalling does not change it. If the address on your account has changed, or you were not the person who originally bought it, use the second form on that page and Mark will send the installer to you personally. The Windows edition is no longer sold and no new trials are issued, but it keeps working and we are still supporting it.
Is the Windows edition still sold?
No. The Windows desktop edition is discontinued and no longer available for purchase. Existing perpetual licenses continue to work, and migration and support options are being finalized for existing customers — you will be contacted directly. AcuityMaster Cloud is the product sold today.
Which Windows versions did it support?
The Windows desktop edition is discontinued and no longer sold. AcuityMaster Cloud has no operating-system requirement of its own beyond a current browser — see system requirements.
What hardware do I need?
If you already have a computer in the exam lane for your EMR, you can typically run AcuityMaster on the same machine. You’ll need:
- A second display connected however your computer supports it — HDMI, USB-C or DisplayPort. No specific video card is required, and on iPad the chart simply runs full-screen.
- A 20–24″ LCD/LED monitor with HDMI (∼$150)
- For video fixation: a monitor with built-in speakers (audio over HDMI)
Will it work with any monitor?
Yes — but monitor size and patient distance affect which lines display correctly. For most exam lanes a 20–24″ LCD is ideal. Small (15–17″) monitors work fine at standard distances.
Can I use a remote control or foot pedal?
Yes. Any standard wireless keyboard or numeric keypad works — on Mac, Windows or iPad. Any programmable USB foot switch works too, since it simply sends a keystroke; see accessories for the third-party units we recommend. A foot switch toggles the pediatric video fixation hands-free. See the Accessories page.
Is there an all-in-one solution?
Yes. Any all-in-one or monitor that meets the browser requirement on the requirements page will do; there is no need for a high-specification machine. Mount it on the wall directly in front of or behind the patient.
What acuity standards is AcuityMaster designed to?
AcuityMaster is designed to ANSI Z80.21 (background luminance 80–320 cd/m²) and ISO 8596 (optotype luminance ≤15% of background), and calculates optotype sizes from the testing distance you enter. Whether a given lane meets those luminance and contrast figures depends on your own monitor and room lighting — hardware AcuityMaster neither supplies nor measures. Verify against your display if conformance matters in your setting.
Where can I find keyboard shortcuts?
In AcuityMaster Cloud, press F1 for the current shortcut list. The PDF shortcut card on the Help & Manuals page is the discontinued Windows edition’s and does not match Cloud.
Can AcuityMaster randomize letter presentation?
Yes. AcuityMaster supports random letter presentation so each exam uses a different letter set. This prevents patients from memorizing chart positions — a common limitation of static traditional Snellen charts.
Does AcuityMaster include mirror mode?
Yes. Mirror mode automatically flips the chart horizontally for display behind the patient via a mirror. Useful for compact exam lanes where a front-facing patient monitor is not practical.
