What they do
Made for the hours before sleep
Sunset lenses are designed for evening use. They reduce the part of the light spectrum that keeps the brain alert, helping create a calmer visual environment before bedtime.
KUGO Lens Guide
Sunset Lenses
Evening lenses designed to help your day slow down naturally. Made for softer light, calmer screens, and a more comfortable transition into sleep.
How to wear them
Best used 2–3 hours before bed
Put them on in the final part of your day — while reading, browsing, working lightly, or simply winding down. The goal is not productivity, but a smoother evening rhythm.
Standard & Premium
Same idea, different execution
Standard and Premium are built on the same concept. Premium simply takes it further through custom manufacturing, higher optical refinement, and prescription possibilities.
Sunset concept
Less stimulation. More evening calm.
Sunset lenses are not meant to preserve a perfectly neutral view. They are meant to help your eyes and brain feel that the day is ending.
How they feel
Warmer, darker, and more sleep-friendly
The stronger the lens, the warmer and deeper the visual effect becomes. Some versions are best for full wind-down mode, while others keep more everyday usability.
Standard 550
The deep evening reset
A ready-to-go solution for those who want the strongest sunset effect without waiting for custom production.
Type
Ready-made
Feel
Deep red calm
Best moment
Late evening
Best for
Maximum wind-down
Standard 550 is the strongest ready-made Sunset option. The visual environment becomes deeply warm, strongly red-toned, and clearly separated from normal daytime light.
It is the version to wear when your main goal is to prepare for sleep, not to keep working. Screens appear darker, colors shift heavily, and the whole visual experience becomes much softer and quieter.
Best for: Late-night wind-down, reading before bed, and evenings when sleep preparation matters more than visual precision.
Premium 550
The premium evening guardian
The same strongest Sunset concept, but in a made-to-measure premium execution, with the possibility of prescription lenses.

Strong red protection

Available
Premium 550 delivers the same sleep-oriented direction as Standard 550, but in a more refined and individually produced form.
It creates a strongly protected evening environment, where the world becomes noticeably warmer, darker, and less stimulating. It is not made for detailed work — it is made for slowing down.
Best for: Evening relaxation, post-work decompression, and anyone who wants the strongest Sunset protection in a premium custom version.
Premium 530
The balanced evening choice
A strong Sunset lens that still keeps more practical usability for evening tasks.

Evening usability
Premium 530 sits in the sweet spot between protection and usability. It still feels clearly evening-oriented, but preserves more visibility and comfort for practical tasks.
The view becomes warm and sunset-like, but less intense than 550. That makes it easier to keep browsing, taking calls, or using a screen for longer without feeling completely cut off from the visual world.
Best for: Evening work, video calls after sunset, and extended computer use when you still want meaningful protection.
Premium 500
The gentlest Sunset version
A softer premium evening lens for those who want a lighter Sunset feel while staying within the same overall concept.
Type
Custom made
Feel
Warm orange glow
Best moment
Earlier evening
Best for
Softer transition
Premium 500 is the lightest Sunset option in the range. It still shifts your visual world toward evening, but in a softer and more approachable way.
It is ideal for people who want the Sunset concept without going too far into a strongly red experience. Think of it as the smoothest entry into evening light management.
Best for: Earlier evening use, a gentler visual transition, and customers who want a premium custom lens with a milder feel.
How to choose
Choose based on how strong you want the evening effect to feel. 550 is the deepest and most sleep-oriented. 530 is more balanced. 500 is the softest and easiest entry into the Sunset category.
What Premium adds
Premium does not change the core idea. It upgrades the execution: custom production, higher optical refinement, and the option of prescription lenses.
When they make the most sense
Sunset lenses are especially useful when you spend the last hours of your day around screens, artificial lighting, or bright interiors — and want your evening to feel less stimulating.
What to expect visually
As the lens gets stronger, the world becomes redder, darker, and less neutral. That is not a drawback — it is exactly what makes the environment more suitable for evening rest.
