The Dangers of Blue Light at Night
The modern era is defined by unparalleled access to visual technology: our digital devices and high efficiency indoor lighting enable us to work and play around the clock - but these gains come at a great hidden cost to our health.
Today's shift toward a digital-centric, indoor lifestyle has massively increased our exposure to night-time blue light. Our clinical data shows that even with "low-blue modes" and conventional blue light blocking eyewear, night-time blue light exposure may exceed recommended levels.
Consequences: Fatigue & Stress
When our eyes are exposed to excess blue light in the evening and night-time hours, an increase in stress-inducing cortisol is triggered, delaying the onset of natural melatonin production and causing symptoms similar to jet lag the next day: fatigue, loss of focus, and an increased appetite for unhealthy food.
Over the span of weeks and years, chronic exposure to excess blue-light at night causes widespread decline to human health. Studies have linked night-time blue light exposure to increased incidence of diabetes, cancer and industrial accidents.
Introducing BLUESAFE 24 Lenses
We designed the NightShift GT lens to deliver an optimal balance between effectiveness and vision quality. By filtering a specific narrow bandwidth of blue light responsible for circadian clock synchronization, NightShift GT lenses protect circadian health while simultaneously preserving brightness and color vision.
The Graduated Transmission (GT) profile increases blue light blocking in the upper field of view, reducing blue light exposure from overhead lights in commercial and residential indoor environments while leaving the lower portion with an increased light transmission for improved mobility and functional task performance.
The 𝘽𝙇𝙐𝙀𝙎𝘼𝙁𝙀 24 Difference
We believe that your vision should not be hampered by annoying backside reflections and smudges, which is why we include premium anti-reflection coatings and a superhydrophobic top coating that resists adhesion of dust and oils, ensuring that your lenses stay clear and free of distractions.
Unlike glass and CR-39 plastic lenses which are heavy and prone to breakage on impact, our lenses are formed with ophthalmic-grade polycarbonate: a lightweight plastic with exceptional clarity and impact resistance.
Optimized Functional Vision
BLUESAFE 24 lenses are built from the ground up to strike the optimal balance of effectiveness and functional vision performance. Other lenses that use blue light "cut-off" filters block more light than is needed, resulting in high color distortion and low brightness, interfering with everyday use. Our patented BLUESAFE 24 lenses are designed to deliver exactly the right amount of blue light blocking, protecting circadian health while preserving brightness and supporting functional color vision.
Proven in Research Studies
BLUESAFE 24 lenses were developed following more than two decades of research at the Circadian Lighting Research Center, Harvard Medical School and the University of Toronto. Drawing on insights from our affiliation with the CIRCADIAN® group of companies our products are based on results of extended duration studies of human performance and wellbeing in demanding 24/7 mission-critical settings including the healthcare, transportation and energy sectors.
Patented Lens Technology
The BLUESAFE 24 innovations in lens design and methods of protecting circadian health have been recognized by patent offices around the world as original inventions worthy of protection. We are dedicated to continuing to push the envelope for 24/7 blue light protection with new products in the years to come.
Ultralight Hypoallergenic Frames
BLUESAFE 24 eyewear are made from optical-grade TR-90 Nylon, the same material found in the world's top premium sports eyewear and active sunglass brands. TR-90 is 30% lighter than acetate, has excellent chemical resistance, and is highly resilient to repeated mechanical stress.
Owning a pair of glasses means you'll also need to protect them from damage and keep them clean. That's why every pair of BLUESAFE 24 eyewear is shipped with a custom fitted rigid zipper-case, oversized microfiber cleaning cloth and a comprehensive user instructions guide.
