Spectral control works like a visual equalizer by selectively managing the light wavelengths and blocking out the harshest ones. Haze and glare are dramatically diminished, contrasts is enhanced, and your vision is sharper all while blocking out distracting blue light which causes eyestrain and fatigue.
By managing colors within the visible light spectrum, Spectral Control technology gives you stunning, high-definition contrast and color enhancement. This essentially gives your eyes control over the light, resulting in crisper vision and amazingly clear images.
