Iris Pro
Iris is the most advanced blue light filtering software available, going beyond simple color shifting to address Pulse Width Modulation (PWM) flicker. It allows for granular control over color temperature and brightness without increasing screen flicker.
Ingredients & Purity
Software-based solution that manipulates the video card's LUT (Look Up Table) to eliminate blue light and control brightness via software rather than hardware PWM.
Scientific Evidence
Built on established circadian biology research regarding the impact of 450-480nm light on melanopsin suppression.
Brand Transparency
The developer is highly active in the biohacking and health community, providing extensive documentation on the physics of light and screen technology.
Value Assessment
A one-time purchase of $15 is exceptional value considering it can be used across multiple devices to protect circadian health indefinitely.
Why Not Alternatives?
While f.lux is excellent for basic shifting, Iris is the only solution that addresses PWM flicker, which is a major cause of eye strain and headaches for many users. It offers far more customization than built-in OS filters like Night Shift.
