Beyond Clarity, Unveiling Unmatched Durability and Protection
Step into a world where vision is not just seen but experienced—welcome to KUGO, where our lenses are meticulously crafted to align with human origins and natural circadian rhythms. Each variant serves a unique purpose, ensuring that your eyes receive the care they deserve. Since 2018 we have been searching the market to find the lenses those would meet KUGO requirements. We have tested hundreds of lenses from various vendors, measuring and testing them to finally define,create and started to make KUGO lenses. Each pair of lenses for KUGO glasses is tested by our team before they are ready to be fitted for your KUGO glasses model. KUGO lenses have all the attributes of exceptional product like enhanced scratch-resistantance, dirt-repellency, improved cleanability, water-repellency, ultimate lens lifespan, enhanced visual comfort and superior ability to our competitors we offer doble sided antireflex to ensure you won't get any secondary lights of unwanted light wavelenghts.
Sunset
As the sun goes down, your brain naturally expects warmer, lower-energy light. Exposure to shorter wavelengths after sunset can suppress melatonin, delay sleep onset, and place chronic stress on the nervous system. The Sunset Lens filters these wavelengths, allowing melatonin to rise naturally and supporting smoother transitions into deep, restorative sleep.
KUGO 550
Redefining Restful Nights
(sleeping/bedtime)
Introducing the game-changer for bedtime rituals, KUGO 550 lenses. With a calming red tint, these lenses block 100% of blue and green light up to 550nm. Wearing them 2-3 hours before bedtime induces instant sleep by supporting melatonin production, even in the digital age. Ensure a tranquil night's sleep with these must-have lenses, redefining the way you rest in the era of digital illumination.

Over time, consistent circadian alignment plays a foundational role in overall wellbeing. Better sleep quality supports metabolic health, hormonal balance, cognitive clarity, and emotional resilience—key pillars of long-term vitality. By reducing nightly circadian disruption, the Sunset Lens helps lower cumulative physiological stress, a factor increasingly linked to accelerated aging.
KUGO 530
Balanced Evening Support
(sleeping/reading/bedtime)
Blocking light up to 530 nm removes the most disruptive blue and blue-green wavelengths while maintaining a more natural visual experience. This option is well suited for those who want strong circadian protection without fully eliminating all green light. It supports a smooth rise in melatonin and helps the body recognize that the day is ending, improving sleep onset and quality. With consistent use, it helps reduce cumulative circadian stress—supporting hormonal balance, recovery, and emotional wellbeing over time.

KUGO Sunset
This lens doesn’t just improve how your evenings feel—it supports the long game. By honoring your body’s natural light cues, the Sunset Lens promotes resilience, recovery, and longevity, one sunset at a time.
KUGO 500
Gentle Circadian Transition
(early evening use/social settings)
This lens filters primarily blue light while allowing more of the visible spectrum through. It offers a softer introduction to circadian protection and is ideal for individuals new to light management or those who prefer minimal color distortion in the early evening. By reducing blue light exposure after sunset, it helps prevent unnecessary melatonin suppression while still allowing visual comfort and social ease.

Daytime Performance Lens
Designed for focus, comfort, and visual clarity without circadian disruption
KUGO 450
The Day Lens is engineered for modern indoor life. It selectively reduces high-energy blue light in the 450–460 nm range—the wavelengths most associated with eye strain, visual fatigue, and glare—while preserving the light needed for alertness and circadian daytime signaling. This makes it ideal for working at a computer, driving, and spending long hours under artificial lighting. By easing visual stress without dulling perception, it supports sustained focus, comfort, and productivity throughout the day.
