Features

The Acuity Pro digital acuity system was developed by doctors and encompasses over 20 years of crowdsourcing enhancements. Our impressive feature set was developed with our users in mind.

Acuity Pro is a fully customizable software solution that provides a comprehensive digital visual acuity chart system with integrated patient education and practice marketing tools. Our software can be purchased {link to shop page} as a standalone product or as an all-in-one system with our recommended hardware and peripherals.

We proudly offer free technical support to all of our customers, with no add-on tech support fees after the first year (or ever!) A helpful training tutorial video will be included with your purchase, but you can also contact us via phone or email for help – anytime you need it.

Digital acuity testing allows you to complete your patient refractions, not only faster, but with more accurate results. Our system also integrates with Marco, giving you an even more streamlined patient exam experience.

When you replace your bulb projector or current digital system with Acuity Pro, you are buying a disaster-proof system for your practice. Our customer service team is standing by to help you in the event of an emergency, and we can get you up and running again by moving the license key to another Windows computer, reinstalling Acuity Pro, and getting patient flow back to normal in minutes – not days. In the event of a remote malfunction or loss, the keyboard hotkeys can be easily used instead. The eye chart can even be set to work without the Internet!

Acuity Pro Optotypes

Acuity Pro includes Sloan, Snellen, Tumbling E, Tumbling C, Patti Pics ® , Allen Symbols, Numbers, 6 ETDRS Charts and more. This extensive selection of charts enables doctors to accommodate patients of all ages and abilities. 

Our digital acuity system features randomization, 3 pseudo-random letter sets for each Snellen line, and precise optotypes (not fonts) in all chart types.

Learn more about available optotypes below.

The Acuity Pro Smart Randomization feature provides a mechanism for randomizing any chart using algorithms that nearly eliminate embarrassing letter combinations. We have also developed a work-around for the Snellen chart that provides three unique pseudo-random single line sequences. Although Snellen is the most familiar optotype, Sloan is more accurate and only has one vowel, reducing the number of words that can be formed. Select ‘S’ for the Snellen Chart.

Standard Sloan letters, which have the same width and height (5×5 aspect ratio), are included with Acuity Pro.  There are 10 letters in this optotype set. Some Snellen letters are 4×5 and some are harder than others. Sloan letters, also known as Bailey-Lovie optotypes, all have the same level of difficulty. The Sloan optotype is used in the ETDRS chart, which is the standard for vision research. Select ‘R’ for the Sloan Chart.

The Tumbling E and C charts are great for young children, non-speaking, or non-English speaking patients where single-letter mode is preferred. Standard instructions would be to tell the patient to point (up, down, left, or right) to the direction the “table legs” are pointing or in the direction the wheel is broken. Select ‘E’ or ‘C’ for the Tumbling E or C chart, respectively.

The number chart, just like the Tumbling C and E charts, helps with patients who may have trouble with letters. Select ‘N’ for the number chart.

The chart consists of only the letters H, O, T and V. The patient is given the HOTV card, included with Acuity Pro, and asked to point to the letter on the card that corresponds with the letter on the screen.  The simplicity of this chart allows it to be used with non-verbal patients, patients with developmental disabilities, and patients who do not know (or are too young to know) the English alphabet. The HOTV and Patti Pics ® response cards  are included to increase accuracy when testing young children and others who have difficulty with standard charts. We believe these charts are more accurate than the Allen picture chart and suggest the HOTV or Patti Pics ® chart as the chart of preference for this patient population. Select ‘T’ for the HOTV chart.

The picture chart is another way to test children. High-resolution monitors provide the ability to display this chart down to 20/10.  Press the F4 key to change to this optotype.

Our newest pediatric chart, used under license from Precision Vision, Inc. ® Response card are included. Therefore, the patient does not have to know what the figures are called, but just points to the matching one on the response card. Select ‘P’ for the Patti Pics ® chart.

Acuity Pro includes the standard 12-point, 3-line astigmatic wheel (or clock dial) and the ‘shower drain’ astigmatic chart. The astigmatic ‘A’ button toggles between the charts each time it is pressed.

Acuity Pro includes the six standard ETDRS charts to meet the protocol requirements for research. Select ‘I’ to toggle through the ETDRS charts. The variable contrast feature is available for these charts as well as randomization.  Press ‘J’ for the variable contrast feature.

Acuity Pro Chart Features and Customizations

We believe that one of the most important features of Acuity Pro is our software’s ability for smart randomization in all chart types. Doctors need to know that patients aren’t memorizing the chart combinations, especially for patients who need weekly or monthly eye testing.

Our total randomization functionality ensures that you will possibly never have the same sequence twice, but we have also built in a limited randomization function for the Snellen chart that lets doctors use a few selected sets that only they have memorized.

Learn more about our chart features and customizations below.

This feature allows relative contrast from 0 to 30 percent and is a great way to test pre- and post-LASIK patients for contrast sensitivity, as well as cataract patients pre and post op, MS patients, and anyone needing another form of vision assessment. . Press ‘J’ to invoke this feature.  Routinely done by selecting a single row of 20/40 letters, the contrast is gradually reduced by using the – key on the remote until they can no longer see letters, then gradually step back up using the + key until just visible. 

Use red/blue glasses to check fixation disparity.  The fixation disparity ‘F2’ button is another dual-function button that toggles between a fixation disparity chart with a fusion lock and one without.

Some doctors prefer to use a vertical line of letters for phoria testing. Press ‘V’ to invoke this feature. Please note this feature is only available as 20/40.

Use the red/blue glasses or red/green (check preference in setup) to check binocularity with your patients.  It is a great way to check for malingering.  Acuity Pro provides the option to adjust the red/blue screen to get the perfect color block. 

This is a standard red/green overlay, which is available for all optotypes.  It can be used with single-letter, single-line, or multi-line displays, all letter sizes, and mirrored setups.

A single line of letters is displayed by pressing ‘L’. This feature works for all optotypes. The line can be shortened – or lengthened – one letter at a time by repeatedly pushing the ‘L’.

Depending on optotype size, up to 4 lines of letters can be displayed at one time. Multi-line is accessed by pressing ‘U’. Based on user request, choose 4, 3, or 2 lines of letters on the multi-line screen by pressing ‘U’ repeatedly to change the number of lines.

Press ‘O’ for ‘One Letter’ display. This feature works for all sizes and optotypes and is often used for ductions.

A standard white on black Fixation Dot is available by pressing ‘D’. It can be resized using the ‘+’ or ‘-‘ keys.

The Smart Randomization feature (Snellen chart only) creates a random line of letters that have a recognition difficulty equal to any other random line of letters.  Some Snellen letters are more difficult to recognize than others.  Examples of difficult letters to recognize are B and S.  Easy letters are T and L.  With Smart Randomization, each line is equally as difficult as any other random line. It makes acuity testing more accurate.  Also when randomizing, the default Snellen letter sequence is the first sequence presented for each Snellen size so you don’t have to worry about looking at the chart each time you change size.  Even if you have ‘Randomized’ the current display, when you change the letter size up or down, the standard sequence will be the first displayed for the next set of letters.  If you would rather have random letters ‘Always On’, just go into the control panel and check the ‘Always Random’ box.  This will always display a random letter sequence.

This feature puts a mini (sizeable) version of the Acuity Pro screen on the desktop monitor.  In a direct room, this allows the doctor to simply look at the desktop screen to see what is on the Acuity Pro screen.

Press ‘K’ to display the crowding bars around a single optotype.  This is the most accurate way to test acuity on an amblyopic eye. It adds “visual noise” to the single letter, simulating more than one letter being presented

Speedy Acuity was introduced by Acuity Pro per user request.  It provides a single or double column of descending size optotypes for that really quick acuity check. Press ‘Y’ to toggle between single and double column display. Randomization works well on this chart mode

For mirrored rooms, enable the Mirror Display feature in Preferences by pressing ‘H’ and clicking on the Mirror Display option. The chart is displayed in a reversed presentation. As opposed to mirrored rooms with a bulb projector, this feature requires only one mirror and it does not have to be a front surface mirror.

All optotypes can be displayed in LogMAR size and notation.  This feature can be set in Preferences by pressing ‘H’ and selecting LogMAR.

Introduced in Version 8, this user-requested feature provides three known letter sets for each line of letters.  For example, from the Snellen chart, press the ‘2’ on the remote or keyboard to display the default Snellen 20/20 line: T Z V E C L.  Press ‘2’ again, and L O Z B D E is displayed.  Press ‘2’ again, and 

V F N S P Z is displayed.  Press ‘2’ again, and you are returned to T Z V E C L.  This is great for straight room, single monitor, or All-In-One computer setups where the doctor is facing the patient and cannot see the screen without turning around.  Instead of pushing the random button, press the remote or keyboard key corresponding to the current acuity row to display a different line of letters that you know – but the patient doesn’t.

This user requested feature completely blacks the screen.  Instead of having to turn the  monitor off press ‘B’. We have also added a second screen, the ‘white out’ screen.  Press ‘B’ again to switch back and forth between black and white screens. This feature is also handy when patients are left in the room alone and want to play with the remote or the computer, since it appears it isn’t on.

The optotype size can be displayed using any of the four display options. Press ‘H’ to select.

You have the option of ANSI standard spacing for the displayed optotypes. Open Preferences by pressing ‘H’ and check the ANSI box.  All multi-line and single-line displays will be spaced according to the international ANSI standard, which means there is an equal amount of space between letters that is the width of letters on that line.

This feature displays a split-screen red/green field that contains two sets of concentric black circles.  This is for doing a red/green balance.

This customization helps make exams much more accurate for patients with low vision.

Mask a single line or single letter of the chart by pushing ‘M’. This feature reduces the brightness of the screen for patients with light sensitivity.

Acuity Pro Remote and Hotkey Features

Our remote is unique to Acuity Pro and enables you to manage your entire digital acuity system. All functions managed by the remote are also programmed as keyboard hotkeys. This allows Acuity Pro to be controlled by the keyboard in the event your remote is misplaced or temporarily unavailable. The custom Acuity Pro mousepad (and the reverse side of the HOTV handheld card) contains the keyboard map of the Acuity Pro features. For example, push S for Snellen, push 4 for 20/40, push U for multi-line, space bar for randomization, etc.

The remote can be customized to perform macros, which can help you increase the speed of exams by programming a sequence of keystrokes into one button. This increases the  speed of the exam by reducing repetitive keystrokes or button pushes.

For example, to start each patient with the Sloan chart with 4 rows starting at 20/40, push one pre-programmed macro key to immediately display that configuration, regardless of what is currently displayed on the screen.  Or if there is a frequently used pathology image, create a macro to go immediately to that image with one button push. 

Learn more about our remote and hotkey functions below.

The remote buttons are labeled consistently with the Acuity Pro keyboard hotkeys. An overlay on the remote details the function of each button. For example, the button with the label ‘S’ has the word ‘Snellen’ written below it.  Pressing this button brings up the Snellen chart exactly like pressing the ‘S’ key on the keyboard. Programmable buttons (F5– F11) are available for customization.

User-defined keys (F5 to F11) are available that allow the assignment of a sequence of hotkey keystrokes to a single Function key. This allows a single key to display a 20/25 line or a single key to jump to a single line display of 20/60 letters or whatever you want. An entire exam sequence of charts can be assigned to a single button on the remote. Access each step of the sequence by repeatedly pressing the assigned Function key.

As mentioned, Acuity Pro can be controlled with the standard keyboard.  Every function and display option can be accessed by a single keystroke called a ‘hotkey.’  We have tried to make the keys as intuitive as possible so they will be easy to learn. Most of our users are able to become familiar with the keys after using the program a few times. The Acuity Pro mouse pad or the back of the HOTV card can also be used for reference.

Branding and Marketing

Acuity Pro also features a library of over 200 slides with informational patient and product information, famous quotes, unusual trivia, general health tips, etc. This is a fully customizable feature, and doctors can modify existing and/or add new images.

New image slides can easily be added by saving PowerPoint presentation slides as JPGs (or other editing and presentation apps that can convert content to JPGs) and importing them into Acuity Pro. 

Patient Education

Acuity Pro was the first digital acuity software system to incorporate pathology slides and animation videos for fixation and patient education. It is one of our most popular features.

Our software includes an image library of common conditions that can be used for patient education. There are also videos available, and your custom photos and videos can easily be added. These can be easily accessed via the remote or keyboard hotkey. You can also create slideshows that incorporate a variety of images and videos to play automatically as a slideshow/screensaver when not testing acuity.

Acuity Pro includes approximately 50 high-resolution images of common ocular pathologies. These images are invaluable in explaining ocular conditions to patients in a professional and expeditious manner. This feature alone can shave minutes off patient education time. 

An intuitive import feature provides the capability to create a custom image library to support the practice’s areas of specialty or for use in creating custom slide shows.  Think of how much easier and faster it would be to show the patient a picture of a posterior subcapsular cataract!

During your patient exam, you can easily access the images by pressing ‘Z’ to access the Photo Gallery. Press the ‘Up’ or ‘Down’ arrow on the remote (‘Page Up’ or ‘Page Down’ key on the keyboard) to quickly scroll through the list of all available images.  When you find the desired title, press ‘Select’ on the remote (or ‘Enter’ on the keyboard) to display the image. The titles are large enough to be seen from across the room so you can browse from the exam chair. The video library selections are accessed in the same manner.

Acuity Pro supports unique slideshows and provides easy customization of pathology slide decks, promotional material, or other topics of interest. Only imported photos can be selected for the slide show. There is also an option to set the delay for each slide change. After pre-testing, have the technician start a slideshow with internal marketing messages, scenic slides, or anything else you want to display. What a great way to educate patients about eye health, unique aspects of your practice, or your life!

Videos are an excellent way to maintain a child’s attention while performing retinoscopy or to show practice promotion videos. Video can also be helpful to educate a patient about an upcoming procedure before asking them to sign the consent form.

We provide some educational videos within Acuity Pro, but you can also import your own. Included are several cartoons and a punctal plug insertion video. Video playlists can also be created.
