Big Update and Rename

written by Levi Zurcher on 2026-01-01

I just released a big update I've been working on for quite some time now. Here are some of the changes:

• I'm changing the name from Tritheia to Eyeona. I felt the old name was just awkward to say. I wanted something that rolls off the tongue better. I also made a cooler looking logo to go along with it.
• I've been working to make it usable for vision screenings and as a "base station" for therapy sessions and testing:
  • Dual screen mode: When the computer has dual monitors, one is used for the therapist/examiner interface and the second is used to display graphics to the patient. Enable in the settings menu. It can still be used in the classic single screen mode that you're used to and will automatically revert to this if only one screen is available.
  • Additional locations can be added and designated as vision screening sites. When logged into a screening location, it's streamlined for smoother screening workflow and many menu options are disabled (since it's going to be used more often by non vision professionals who are not part of your organization.)
  • I've designed specialized hardware to go along with this, which will be available to other clinics in the future.
• Screen calibration can now be performed in either metric or imperial units, so users don't have to stress about finding a metric measuring tape.
• There are lots of bug fixes and enhancements... too many to mention them all here!
