Key Benefits
Roebling Sazerac Crystal Anti-Fatigue features a proprietary blue light filtering solution designed to effectively improve the quality of sleep, reduce digital eye strain, and support clearer cognitive performance. Felix Gray reinvented blue light glasses grounded in science to reduce the impact of overexposure to high-energy visible light from digital devices and artificial lighting, which may affect sleep quality and cause visual discomfort. Its double-sided anti-glare coating reduces reflections to enhance visual comfort in various lighting conditions.
Felix Gray’s anti-fatigue lenses function as low-power readers, featuring a gentle +0.25 boost designed to ease eye strain and support near-focus tasks. This subtle enhancement helps keep your eyes feeling comfortable throughout long workdays, reading sessions, and screen use—without distorting your vision.
The lenses also offer up to 15x more effective protection against harmful blue light, along with 100% UVA and UVB protection, shielding the eyes from harsh rays without altering colour perception. Made with Grade A ophthalmic-quality materials, Roebling Sazerac Crystal Anti-Fatigue delivers sharp, distortion-free clarity. The hand-finished organic acetate frame adds refined craftsmanship to this high-performance design.
