Filters intense blue and some green light (up to 500nm) to naturally support melatonin release as evening sets in.
DESIGNED FOR DUSK TO WIND DOWN
Engineered for the transition hours—when natural light fades but artificial light takes over.
Deeper and Restful NIghts
Helps calm your system, reduce alertness, and signal to your brain—it’s time to sleep.
The amber lens is engineered to filter up to 95% of blue light between 380–500nm, which includes both the high-energy blue light that suppresses melatonin (460–480nm) and wavelengths that overstimulate alertness pathways in the brain.
Evening exposure to artificial light—especially from LEDs, smartphones, and screens—can disrupt the body’s natural production of melatonin, delaying sleep onset and diminishing sleep quality. By blocking this disruptive spectrum, Balterra’s amber lens helps maintain a healthy circadian rhythm while allowing enough visible light for functionality and comfort during evening routines.
Unlike lenses with minimal filtration or clear coatings, our amber lenses provide targeted, biologically relevant protection backed by peer-reviewed research in chronobiology and optical science.
They don’t just change the way you see—they support how your body functions.
The Right Light at the right time
Designed for winding down, without winding up.
Our amber lenses are purpose-built for use after sunset, when your body begins producing melatonin—the hormone responsible for sleep and circadian regulation. These lenses are best worn indoors under low-lux artificial light, typically under 200 lux—including warm household bulbs, bedside lamps, and ambient evening lighting.
Whether you're wrapping up the day, cooking dinner, or reading before bed, these lenses help your body transition into rest mode without the interference of blue light stimulation.
Wear them:
– In the evening under warm, dim lighting
– While watching TV, scrolling, or reading at night
– When dining or relaxing under artificial lighting
– After sunset when outdoors under streetlights or car lights
Not for use in sunlight.
For earlier in the day, use our Yellow Daylight lens. For full night-time protection, transition to our Red Night+ lens.
Where Wellness Meets Design
At Balterra, wellness isn’t an afterthought — it’s designed into every detail. We merge cutting-edge lens technology with refined silhouettes to create eyewear that not only supports your circadian health but elevates your sense of style. From the materials we choose to the forms we sculpt, every decision is intentional. Elegant. Considered. Functional. This is where wellness meets design — for those who expect more from what they wear and how they live.
Use Daytime lenses during the day in indoor or screen-heavy environments to reduce eye strain and support focus. Switch to Night (Amber) in low‑light evening settings—dim lamps, or go Night+ (Red) under intense artificial light—TV's, phones, LEDs, or overheads—for complete circadian protection.
Yes — when indoors and exposed to artificial light. Our lenses are designed to support your circadian rhythm by filtering overstimulating blue light from screens and LEDs.
However, they’re not intended for natural sunlight. For best results, wear them inside — and let real daylight reach your eyes when outdoors.
