Each lens is tuned to a different quality of light — one to cut the sun, three calibrated to specific wavelengths that shift how you see and feel as the day moves. No app. No AI. No login required.
Carl Zeiss optics. Italian-made frame in Grilamid TR90 — light, flexible, near-unbreakable. Three finishes: Black, Tortoise, Crystal.
Every kit includes all four lenses, the frame, a travel case with a slot for each lens, and a microfiber cloth.
Care & Maintenance
Four lenses, one frame, one case, one cloth. That's the whole system.
Rinse the lenses under cool water before you wipe — running water lifts grit that would otherwise drag across the surface. Dry with the included microfiber cloth. No paper towels, no shirt hems, no alcohol-based sprays. The lenses are precision-molded nylon, which is light, durable, and slightly more forgiving than glass — but it scratches if you ask it to.
When you swap, the lens you take off goes back in its own slot in the case. Each lens has one dedicated slot.
Treat the frame like a good pair of shoes. It will outlast most things you own if you don't sit on it.
Size & Fit
One size. Designed to sit well on most adult faces.
Lens width: 45.7mm Frame width: 139mm Bridge: keyhole, fits nose widths from narrow to medium Temple length: 150mm Pantoscopic angle: 9° Front curvature: 8° Material: Grilamid TR90 — a Swiss-engineered polymer used in surgical instruments and high-end frames. Light, flexible, near-unbreakable.
If they don't sit right, any optician can warm and adjust the temples in two minutes. Standard fitting, lighter frame.
Four states of light · One frame · Zeiss BioChrom
One frame. Every state, in the case
The insiders stopped choosing eyewear by shade a long time ago. They choose by state — and swap the lens to meet the light. Four Zeiss lenses, one frame.

One frame, four Zeiss lenses, travel case included.
590 nm · warm
Every colour is a frequency. Most eyewear pretends that doesn't matter.
Tint isn't decoration — it's a filter on the light that reaches you. Zeiss spent years in vision and neuroscience labs proving what colour does to focus, calm and alertness. We put four of those states in one frame, and let you choose which light you need.
We're a cult, not a clinic. No miracles — just very good light.

04 — The ritual
How members actually wear it.
01
Flow
Screens, long focus, low-contrast light — cut the blue and hold your attention where it belongs.
02
Calm
After the stress, out in the bright. The wavelength the eye rests on most easily.
03
Refresh
Slow mornings, mid-afternoon dips — the light that reads as wake-up.

Love this biohacking glasses. I bought 2 and my husband was quick to take ownership of one. We used it for everything. The lenses are easy to change and the fit is really comfortable.

The glasses are so soothing to the eyes. I feel far more refreshed since I wear them and find it hard to take them off, once you get used to them.

After getting artificial lenses in both eyes, I battled with brightness, particularly at night, where sunglasses are simply too dark. Now I wear the blue shades, as soon as I step into my car - and it makes the world of difference!!!
I am still experimenting with what shade to wear at the PC.
I also want to mention, that I am 67, so hands and fingers get a bit more "clumsy", but changing the shades on the fly is as easy as pie!!
Thank you for following through with this idea - for me it is a game changer!
