The Science of Blue Light

Understanding why blue light matters:

1. Circadian Rhythm Disruption: Blue light (450-495nm wavelength) signals "daytime" to your brain's suprachiasmatic nucleus, suppressing melatonin and keeping you alert.
2. Digital Eye Strain: High-energy blue light causes more scattering in the eye, contributing to eye fatigue and discomfort during prolonged screen use.
3. Sleep Quality Impact: Studies show that 2+ hours of evening screen use without filtering can delay sleep onset and reduce sleep quality.
