See for yourself
Red gets through, blue and green don't. That's why the red lens is for the night and the softer amber one for the day.
Why
You've spent hours on your phone, laptop or TV. You go to bed and your body is still in evening mode. It's not the brightness: it's the colour of the light.
Some cells in the retina, sensitive mainly to blue light, tell your body clock whether it's day or night.
At night they keep sending the daytime signal, and melatonin, the hormone that prepares sleep, arrives later.
It filters the part of the spectrum that weighs most in that signal and lets red through. You can still see and carry on with what you're doing.

FAQ
It depends on the time of day. Daylight is for daytime in front of screens and LED light. For the night, the two red models have the same lens: Nocturne is an acetate frame you can wear at dinner or out of the house; BlackOut is wraparound, with foam, and also blocks light coming in from the sides.
Not with the red ones: neither by day nor by night, nor for anything that requires telling colours or light signals apart. With Daylight we don't recommend driving at night either: any tinted lens reduces the light that reaches you.
The red ones, one or two hours before bed and until you turn off the light. You don't have to switch anything off or change rooms. Daylight, during the day in front of screens.
Yes, with the red ones. The lens lets red through and blocks the rest, so the image is tinted and colours can't be told apart as usual. That's exactly what it's meant to do. With Daylight you'll notice a warm, much softer tone.
That evening light delays melatonin is well measured. That filtering it helps you sleep is backed by promising but small studies: in one, people with insomnia who wore amber lenses for two hours before bed slept better than with unfiltered lenses (Shechter et al., 2018). They are not a treatment: if you sleep badly persistently, see a professional.
No. They are standard adult-size frames and BlackOut has foam all around. If you wear prescription lenses, ask your optician about a red or amber filter on your own lenses.

“Resting better is key to higher performance. Throughout my career, I performed much better when I rested well. I now use Red Horizon glasses before bed and I notice I get sleepy much earlier and rest better.”
