One lens, at the right time
As soon as it gets dark outside, turn on SLEEP. You can leave your screen on.
The lens filters out the blue part of the light that inhibits your melatonin
Your melatonin production starts earlier, so your evening works with you instead of against you.

Research Liset 2022
Fall asleep faster
Blue light after sunset inhibits your melatonin. Liset (2022) found that wearers of blue light blocking glasses had an average melatonin onset 28 minutes earlier. Wear SLEEP for the last 2 to 3 hours before sleep.
Research Lockley 2003
Your brain interprets light as a signal that it is still daytime. After sunset, blue light from screens and LED lighting suppresses your melatonin production. This delays the onset of your natural sleep signal.

Your screen can stay on
You don't have to change your evening routine. No putting away screens, no turning off lights. You put on SLEEP and simply finish watching your series, while the lens filters out the blue light.
The lens 380 to 520nm
Filters precisely the right light
The orange lens filters out the part of the light spectrum to which your circadian rhythm is most sensitive, between 380 and 520nm. Precisely the blue and blue-green light that inhibits your melatonin, and nothing more.
The first 30 days
You get 30 days to try on your glasses. Feel free to wear them. If you don't like them, you can return them for free, even if worn.
Your first night
You put on the glasses as soon as the sun sets. The screen immediately looks warmer and softer on your eyes. Nothing else changes about your evening; you just finish watching your show.
The first week is over
The orange no longer catches your eye. More and more often you find yourself wanting to put your phone away earlier in the evening, as if your body is picking up on the signal that it's evening again.
It's becoming a habit
You automatically reach for SLEEP when it gets dark. The evening feels calmer, with less bright light directly in your eyes just before sleeping. Many wearers say they find it easier to unwind.
Part of your evening
The glasses are just part of life now, like your phone on the nightstand. You only notice the difference when you forget them one evening and the screen light suddenly feels harsh and startling.
You decide
After a month, you'll know what your evenings with SLEEP feel like. If you like it, you simply keep wearing it. If you don't, you can return it for free, even if worn. The risk was on us.
