Filters intense blue light (380–445nm) to ease tension from screens and artificial light.
Made for Screen heavy Days
Designed for workdays under LEDs and long hours on digital devices.
Sharpen Focus & Clarity
Enhances contrast and reduces screen glare to support concentration during long hours of digital work.
Balterra’s yellow lens is designed to block 97.15% of blue light in the 380–445nm range—precisely where artificial lighting and screens emit the most biologically disruptive wavelengths. This part of the spectrum is known to contribute to digital eye strain, mental fatigue, and overstimulation during the day by interfering with natural cortisol and alertness rhythms. While the lens does create a noticeable yellow hue when worn, that colour shift is intentional: it represents targeted filtration where it matters most. Unlike clear lenses that offer minimal protection, Balterra’s yellow lens minimises digital eye strain, improves visual clarity, and reduce neural overstimulation associated with prolonged exposure to artificial light.
The Right Light at the right time
Designed for the peak of your day.
Our yellow lenses are made for moments spent under artificial light, not natural sunlight. Wear them indoors during daylight hours — in offices, studios, or anywhere screens and LEDs dominate.
Whether you're deep in creative flow, working through your 9-to-5, or navigating digital spaces, these lenses filter harsh blue light without dimming your clarity.
Wear them:
– During computer work or screen exposure
– Under bright indoor lighting
– In co-working spaces, offices, or retail environments
– While commuting on overcast days or through city lights
Not for use outdoors in natural sunlight.
For full protection at night, transition to our Amber or Red lenses when the sun goes down.
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.
