The best news for my Vision Test Battery FrACT₁₀
- Basic operation unchanged!
More good news – Important new features
- PDF output is now possible. With operator intervention the results and the full testing history can be saved in a PDF file – this advances FrACT₁₀ towards 21 CRF Part 11 compliance
- Find it at
Settings>General>Export results to, set toFull history→PDF. - Works best with Chrome or Edge, there a file-save dialog will appear, allowing you to change the suggested filename and choose destination. FireFox and Safari have not (yet?) implemented the
File System Access API(specifially,showSaveFilePicker), so there FrACT₁₀ falls back to normal download: PDF appears in the download folder and the filename is automatic (but sensible 😎). - Automatic filename is »FrACT_YEAR-MONTH-DAY_HOUR_MINUTE.pdf«. If interest is there, I could add the ID and/or eye (below) to this.
- I gratefully acknowledge the nudge and insightful advice by Ursula Garczarek on 21 CRF Part 11 compliance.
- Find it at
- A bug fix for incorrect reaction times (since mid-March, 1000ms too short {thus often negative} if you need to correct).
- Optionally, an ID identifying the test situation, and eye tested can be entered beforehand. This is then saved along with the testing results for permanent storage.

Settings>Misc>ID / eye
- Find it at
- The library “simplestatistics” I’m using for some data crunching had vanished at its old URL. Now I found it again and can give credit.
- Alphabetically sorted Presets – They had grown “organically”, now better organised.
- Improved tooltips, added where missing
- Internal refactoring to simplify
- Fixed bug: Reaction time included the ISI delay
- Even more details in the commit history.
A change, possibly breaking
- The format of the exported data record has changed to embody ID and eye condition. First time in 5 years!
vsExportFormatis now at 6. Position of the decimal marker field unchanged, so parsers need not be adjusted for international number formats. - This reminds us: for ongoing studies, use a frozen version!
