Your eyes have a daylight sensor. It doesn't know it's 10 p.m.
Light-sensitive cells in your eyes respond most to blue light — the signal your brain reads as daytime. Evening lenses filter it so your screens and lamps stop saying morning.

A sunset filter for your evenings.
Amber lenses hold back the blue end of the light from screens and lamps and let warm light through — like watching your evening through a sunset.
Sunset to lights out.

Step 01

Put them on at sunset
Two to three hours before bed.
-
Step 02

Live your evening
Screens, books and TV — just through amber.
-
Step 03

Off at lights out
Sleep in the dark.
Don't wear tinted lenses while driving.
The light science is solid. The glasses studies are small.
Evening light — especially from screens and lamps — shifts your body clock and suppresses melatonin. Amber and red lenses filter the blue end of that light. Here's what the studies found.
Strong evidence that evening light matters; small trials for the glasses themselves. Wear them every evening for 90 days and judge for yourself.

When should I wear them?
For the two to three hours before bed — while you use screens, read under lamps or watch TV. Take them off at lights out.
Can I wear them during the day?
They're made for evenings. During the day, bright light helps keep your body clock on track, so most people go without.
Will they protect my eyes?
No — and we won't claim that. The American Academy of Ophthalmology says blue light from screens doesn't damage your eyes. These glasses are about evening light and your body clock.
Can I drive with them?
Don't wear tinted evening lenses while driving — they change how you see colors such as traffic signals.
