The idea
Concept
A screen can pre-adjust its image so that by the time light reaches your eye, it appears corrected — no glasses, no hardware.
Android app — built & tested
Platform
Correction worked inside the app. Proved the concept was real and technically feasible.
Android — system-wide correction blocked
Discontinued
Android's security model prevents apps from applying overlays to other apps or the home screen. Correction was restricted to inside DOA — not useful enough.
Browser extension — pixel access blocked
Discontinued
Browser security prevents extensions from accessing screen content at the level needed for real-time correction. Another architectural dead end.
Windows desktop app — shipped
Platform
OS-level screen access solves the platform problem. Real-time correction across every app and window, at 60fps.
Beta — live correction + feedback
Feature
Static correction based on your prescription. Collecting real-world feedback across different screen setups and prescription profiles to improve the next stage.
Colour blindness modes
Feature
Protanopia, Deuteranopia, and Tritanopia corrections — active alongside any prescription. Improving the matrices based on user feedback.
Prism Correction
Correction
Allowing users with eye misalignment issues to be able to use their screens easily.
Extending correction to higher prescriptions
Correction
Current correction is strongest for mild to moderate prescriptions. Work is underway to push reliable quality further — toward −8D and beyond.
Smarter starting correction
Correction
Your correction will be informed by real feedback from users with similar prescriptions and setups — not just your numbers on paper. Better from the first session.
macOS support
Platform
The same product, rebuilt for macOS. After the Windows version is stable and the calibration system is mature.
Content-aware correction
Feature
Reading text and watching video need different things. DOA will detect what is on screen and adjust automatically — sharper for text, smoother for video.
Vision change alerts
Feature
If your correction preferences shift noticeably over time, DOA will suggest you check in with your optometrist. Your vision can change — DOA is well placed to notice.
Sharper text on all display types
Correction
Correction at a finer level, accounting for how different monitors display individual pixels. Noticeably sharper text, especially on high-resolution screens.
Dynamic correction — screen adapts to you
Correction
Your webcam estimates your distance from the screen in real time. The correction adjusts automatically as you naturally move — no manual setup.
Correction without a prescription
Feature
Not everyone has access to an optometrist. A guided in-app test will let DOA estimate and apply the right correction without requiring a formal prescription as input.
Prism Realignment
Correction
Using prism adaptation therapy to try to realign user eye (Study).
Correction built into monitors
Hardware
Working with display manufacturers to build correction directly into monitor firmware. Sit down, it recognises your profile, your screen adjusts. No install needed.
Android: correction at OS level
Platform
Not as an app, as part of the OS itself, built with device manufacturers. The version of the original Android idea that works properly. Requires a different kind of partnership.
