Built into ZenOptix
A test chart built into
your practice software
Controlled from the keyboard you are already using. The ZenOptix digital Snellen chart opens full screen on the patient's monitor from any page, and the numpad drives it without your focus ever leaving the eye examination.

What is the ZenOptix test chart?
The ZenOptix test chart is a digital Snellen chart built into ZenOptix optical practice management software. A clinician opens it from the test chart icon in the top bar, from any page, including part way through an eye examination. The chart appears full screen in its own window on the patient's monitor, and the clinician controls it from the number pad on their normal keyboard while carrying on typing in the exam record. Each consulting room is calibrated once so letters are drawn at their intended physical size for that room's test distance.
Numpad control
Control the chart without leaving the exam
- The number keys along the top of the keyboard keep typing normally
- Works whether you are in the main ZenOptix window or the chart window
- Press / and * together to hand the numpad back for typing, such as entering a prescription
- Press them again to take control of the chart back
- On-screen buttons in the control panel mirror every key, as a backup
The test chart icon in the top bar glows blue while the numpad is controlling the chart, so it is always clear which mode you are in.

Calibration
True size in every room
Your test distance
Set each room to 3, 4, 5 or 6 metres, and to direct viewing or a single mirror.
Mirror rooms handled
In a mirror room the chart is shown reversed automatically, so it reads correctly in the mirror. Your preview never is.
Calibrated with a ruler
A guided on-screen calibration with a ruler sets the monitor's real scale.
Never shrunk to fit
Letters are never shrunk to squeeze onto a small screen. You are told if a chart does not fit.
Change is noticed
If the monitor or screen settings change after calibration, ZenOptix prompts a recalibration.
Your choice of font
Choose a chart font per room: Optician Sans by default, Geometric, or a Rockwell-style slab serif.
On the patient's monitor in a mirror room
As the patient reads it in the mirror
Rows are spaced evenly, like a printed Snellen chart, with 6/x acuity labels. Illustrations are not to scale.
Isolate
Isolate a line or a single letter
Full chart
Every row, with its acuity label.
One line
The other rows are hidden in place.
One letter
A single letter, exactly where it was.
All day
Ready for a full clinic
Stays up all day
The chart does not blank or sleep while ZenOptix is behind other windows.
Ends cleanly
Closing the chart, signing out or switching branch ends the chart session cleanly.
Chart content only
The patient's screen shows chart content only, never patient information.
The right people
Only clinicians who can carry out eye examinations can open it, and locums only on a published shift. Managers set up and calibrate the rooms.
What you need
No extra hardware
Any standard monitor
The chart runs full screen in its own window on the patient's monitor, in a normal browser. A portrait monitor suits a full chart best.
The keyboard you have
Control comes from the number pad on the keyboard you already type on.
No separate software
No separate chart software, remote control or dongle.
From any page
Open it from the test chart icon in the top bar, including part way through an eye examination.
FAQ
Test chart questions, answered
No. The chart opens in its own window on the patient's monitor, full screen, on any standard monitor and browser, and you control it from the number pad on the keyboard you already use. There is no separate chart software, remote control or dongle. A portrait monitor suits a full chart best.
Yes. While the chart is open the numpad drives the chart, even while you are typing in the exam record on the main screen, and the number keys along the top of the keyboard keep typing normally. To type on the numpad itself, for example to enter a prescription, press / and * together to hand it back, then press them again to control the chart.
The test chart icon in the ZenOptix top bar glows blue while the numpad is controlling the chart. The control panel also shows whether focus is on, and its on-screen buttons mirror every key as a backup.
Each consulting room is set up once with its test distance of 3, 4, 5 or 6 metres, and a guided on-screen calibration with a ruler sets the monitor's real scale, so letters are drawn at their intended physical size for that distance. Letters are never shrunk to squeeze onto a small screen; you are told if a chart does not fit. ZenOptix prompts a recalibration if the monitor or screen settings change.
Yes. A room can be set up for direct viewing or a single mirror. In a mirror room the chart is shown reversed automatically so it reads correctly in the mirror, while the clinician's preview is never reversed.
Pressing + on the numpad moves to the next chart, cycling through several letter and number charts, so you are not relying on a single layout.
No. The patient's screen shows chart content only, never patient information.
Clinicians who can carry out eye examinations can open it, and locums only when they are on a published shift. Managers set up and calibrate the consulting rooms.
Practices remain responsible for checking that their chart setup meets their clinical requirements.
