Iris
Iris is a macOS app that adjusts screen color, blue light, and brightness settings to help reduce eye strain during computer use.
What is Iris?
Iris is a desktop eye-protection app for macOS that helps users make prolonged screen time more comfortable. It is designed for people who spend many hours on a computer and want more control over blue light, brightness, and display behavior during day and night use. The app includes automatic and manual adjustment modes, plus multiple presets aimed at reading, night work, and other viewing preferences. It also offers controls intended to reduce visible screen flicker and make the display feel easier on the eyes in different lighting conditions. Iris is published by Daniel Georgiev and is also available on other desktop platforms, but the macOS version is focused on native day-to-day use on Mac.
Key features
- Reduce blue light from the display for evening and low-light use
- Adjust screen brightness behavior with automatic or manual control
- Switch between presets for reading, programming, sleep, and general use
- Change color temperature to match day and night conditions
- Use display modes that aim to make long work sessions easier on the eyes

Safety overview
Status: Mostly safe
Iris is legitimate display-adjustment software. To work as intended, it may run in the background and ask for permissions related to controlling display behavior or starting automatically when you sign in. Those requests are normal for this kind of utility. Only grant the permissions you want to use, and if you no longer need the app you can remove it along with its support files.
Recommendation: Keep Iris if you use it to reduce eye strain or manage your screen for night work. If you stopped using its display adjustments, removing it is reasonable and may also stop any login-start or background behavior tied to the app.
