Handcrafted in deep black Mazzucchelli 1849 acetate, biodegradable and plant-based. The blue light–filtering lenses are designed for daily screen use — protecting your eyes from prolonged exposure to digital glare while maintaining natural color balance and visual clarity. The lenses allow natural light to pass through while filtering out the harsh blue tones emitted by screens, computers, phones and artificial lighting, helping to reduce eye strain, dryness, and fatigue from those long working hours. A modern essential for focused work, calm evenings, and eyes that deserve rest.
