Outcomes first
What you get from the screen on your desk.
Red while you keep working
Use OptionCommandR to toggle a live red filter while keeping your desktop usable.
Clear about the difference
A Mac display is not a dedicated panel. Its calculated output is not a measured panel dose. Explore the science.
Two ways
A timed session, or a live filter.
15-minute session
Start a 15-minute full-screen red session, or choose Morning Red or the 30-minute Low Light session. The soft-grid appearance is for wellness and ambiance, not treatment. Press Escape to exit. See how sessions work.
Live red filter · OptionCommandR
Keep your desktop usable while its colors are remapped to red. Toggle the filter with Option-Command-R. Option-Command-Period restores colors and ends a running session.
Straight answers
Straight answers before you start.
Is this 660 nm?
Display P3 red’s published dominant wavelength is about 614.9 nm, a color description rather than a measured emission peak. The app does not provide 660 nm LED or 850 nm near-infrared output.
Is this medical?
No. This is a timed red field and a desktop tint. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any condition. Clinical benefits have not been established for this app.
Is a laptop enough?
A laptop is not a dedicated panel. Calculated output is about 0.2–0.3 mW/cm² at the glass. Choose it for timed sessions and a desktop red filter on hardware you already own — not as a substitute for a measured panel dose.
