🌙 Adaptive Night Guard – Seamlessly adjusts screen temperature based on your local sunset/sunrise times.
🌟 True Color Preservation – Reduces blue hues without distorting critical visuals like photos or design work.

No intrusive ads or pop-ups during use

Behind the Bluelight Filter:
Developed by a Barcelona-based health tech collective, BlueLight Filter’s algorithm draws from 2021 ophthalmology studies on digital eye fatigue. The team prioritizes open-source adjustments, regularly incorporating user feedback into updates.
