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, which was 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.
Colour blindness modes
Feature
Protanopia, Deuteranopia, and Tritanopia corrections, active alongside any prescription. Matrices refined based on user feedback.
Prism Correction
Correction
Users with eye misalignment can now apply prism correction directly through DOA, making screens more comfortable without physical prism lenses.
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.
Color vision calibration game
Feature
An Ishihara plate-based in-app game that lets users identify their color deficiency type before applying a color filter, so the right correction is applied from the start.
Contact lens prescription support
Feature
Users who only have their contact lens prescription can flag it as such. DOA applies the standard vertex distance correction formula to convert it to the glasses equivalent: no optician visit just to get started. Calibration refines the result from there.
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.
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, and DOA is well placed to notice.
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).
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, with 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.
Smarter prism offsets
Correction
Researching finer display-side prism offsets to make screens even more comfortable for users with binocular imbalance.
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.
