When to wear them

A lens for every moment

Switch lenses as the day goes on and the light fades.

01
8 am – 6 pm
Ambris, for the day
During the day — at the office, in class or at your computer. Ambris is a daytime comfort lens, not a sleep lens. In the evening, switch to Solaris, then Noctis.
- Morning — Get some daylight first: it helps set your body clock.
- Daytime — Wear Ambris during your screen hours.
- Evening — Hand over to Solaris 2–3 hours before bed.
02
2–3 hours before bed
Solaris, for the evening
In the evening, once the sun sets or 2–3 hours before bed: watching a show, scrolling your phone, reading under LED lights.
- Sunset — Put on Solaris when the lights go on at home.
- Evening — Keep them on for your evening screens.
- 1 hour before bed — For maximum filtering, switch to Noctis.
03
The final hour
Noctis, before sleep
For the last hour before sleep: your evening routine, a final look at your phone, reading in bed. Never wear them to drive.
- 1 hour before bed — Put on Noctis when you start your evening routine.
- In bed — Keep them on until lights out.
- At night — If you get up, use a red or orange night light.

The science

The science behind our three lenses

Ambris

Ambris filters part of the blue-violet light, the most energetic part of the visible spectrum. Its light tint keeps contrast and brightness, so it’s comfortable to wear for hours. We offer it for comfort and a warmer look on screen, not for sleep — and we don’t claim it reduces eye strain, because good studies don’t show that.

Solaris

At night, blue light (around 480 nm) is the strongest signal for delaying melatonin. The studies that found better sleep used amber lenses worn 2–3 hours before bed. Solaris follows the same approach: an orange tint that stops much of the blue while letting through enough light to read and move around.

Noctis

Melanopsin sensors respond most to blue light, but also, more weakly, to green. A red tint stops both, making it the most complete filter for late evening. It colours your view strongly, which is why we keep it for the final hour, at home.

What we don’t promise. Leading eye-care bodies (the American Academy of Ophthalmology, the UK College of Optometrists and the Cochrane review) have found no good evidence that blue-light glasses reduce eye strain or protect eye health — so we don’t claim they do. The sleep benefits are strongest with orange or red lenses worn 2–3 hours before bed.
