Love the concept and quality of these glasses, but sadly found it quite tricky to find the perfect-fitting frame online.

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.

Suggested use
Wear two to three hours prior to bedtime to help unwind and prepare your body for sleep. Studies measured Felix Gray wearers fall asleep faster, wake up less during the night and hit REM sleep stage 35% faster.
Wear daily during screen exposure or prolonged use of digital devices to help reduce visual discomfort and maintain sharper focus. A large-scale office study demonstrated that wearers’ cognitive performance increases by 47% when wearing Felix Gray glasses during the day.
Clean lenses regularly using a microfibre cloth and lens-safe cleaning solution. Avoid abrasive cleaners and rough materials that may damage the coatings. Store in a protective case when not in use to prevent scratches or warping. Keep away from direct heat or prolonged sunlight to maintain frame integrity.

Great anti-fatigue blue light glasses
These glasses have really helped reduce eye-strain when working on my laptop during the day, and likewise during the evening when watching TV or reading before bed. A great, well-worth investment.
