The Science
Why blue light affects your eyes
High-energy blue light emitted by digital screens has been shown to contribute to eye strain and interfere with natural sleep rhythms - Prolonged exposure, especially at close range, forces the eyes to work harder and can disrupt visual comfort over time.
Filtr uses a selective optical filter designed to reduce targeted blue light wavelengths while preserving Clarity, Color Accuracy, and Touch Sensitivity.
