Cloudstory NightOwl XVIII — Blue-Light Blocking Clear Lens Glasses

The Cloudstory NightOwl XVIII addresses the modern epidemic of digital eye strain through clear lenses with an embedded blue-light blocking chromophore that absorbs 95% of high-energy visible light between 380 and 450 nanometers — the spectrum most intensely emitted by LED screens, fluorescent office lighting, and smartphone displays — without adding any perceptible yellow tint to vision. The proprietary ClearGuard lens treatment achieves blue-light filtering through a molecular absorption mechanism built into the lens substrate rather than a surface coating, ensuring the filtering performance cannot degrade with cleaning or surface wear. The frame is designed for 10–14 hour daily indoor wear comfort, with an ultra-low 17-gram total weight achieved through hollow-wall titanium temples over an acetate front. The temple profile tapers from 4 mm at the hinge to 2 mm at the tip for a natural behind-ear pressure profile that eliminates the headache-causing constriction of heavier frames. Anti-reflective coating on the outer surface eliminates reflected screen images visible to colleagues in video calls, a professional-grade feature not found in fashion blue-light glasses. The optical power is precisely zero, with lens deviation below 0.06 diopters, for non-prescription wearers. Suitable for open-plan offices, gaming environments, and evening device use. Lens width: 53 mm. Bridge: 18 mm. Temple: 142 mm. Weight: 17 g.
