You can work 12 hours at a screen.
Your body can’t.

You start your day with emails. You spend it on calls, code and decks. You end it with your laptop open on the couch.
You want to win at work. You want to be there for your family. You want to stay healthy.
But by the evening, you’re tired, foggy and somehow still wired.
It’s not because you work too hard. It’s because of the light you live in all day.

Your body runs on light.

For millions of years, the sun was our only light. Sunrise told the body: wake up. Sunset told the body: slow down. This daily clock, your circadian rhythm, runs your energy, your focus and your sleep.
Then we built a new kind of light: bulbs, screens, phones. They’re full of blue light, the same signal the sun uses to say “it’s day.” Your eyes can’t tell the difference.

So here’s what happens to you:

During the day, at your desk:

  • Tired eyes. You look at a bright screen for hours, so your eyes get tired.
  • Headaches. Long screen days often end with a heavy head.
  • Dry eyes. You blink less at a screen, so your eyes get dry.
  • No energy by 4pm. You spend the whole day inside under bright artificial light, with almost no sun.

At night, at home:

  • Your body thinks it’s still day. Screens at 11pm tell your brain it’s noon.
  • Less melatonin. Blue and green light hold back your sleep hormone.
  • Tired but wired. You’re exhausted, but your mind won’t stop.
  • Hard mornings. Your body clock gets lost, night after night.

And the next day, you start again, a little more tired.

BUT!

You don’t need to quit your job or throw away your phone.
You just need to give your body the right light at the right time.
Call it light management: the easiest health habit you’ll ever build.

  1. 1. Get morning sun. Go outside in the first hour after you wake up, even for 10 minutes. This sets your body clock for the whole day.
  2. 2. Go out during the day. Take a walk or a call outside, or sit by an open window. Glass blocks part of the sun’s light.
  3. 3. At your screen, wear Day lenses. They block 95% of blue light from screens and office lights.
  4. 4. After sunset, wear Night lenses. They block 100% of blue and green light, so your body knows it’s night, even if you’re still on your laptop.

Live by the sun. Work with your screens.

One system for your whole day

LUCIER Day lenses (yellow) are for work hours: clear, calm and easy on your eyes.
LUCIER Night lenses (red) are for after sunset: your evening signal to slow down, so you can be there for your family, and for yourself.
Most clear blue-light glasses filter only about 20% of blue light. LUCIER Day lenses block 95%.

״I should have bought these sooner. I work in an office and use a computer almost all day, so my eyes were always tired. Since I started wearing the Day lenses, my eye fatigue definitely feels lower. I like them so much that I’m thinking about trying the Night lenses later too.״Office worker · Jason A.
״A whole different level from regular blue-light glasses. I’m an office worker and I’ve been wearing regular blue-light blocking glasses for 2 years. Every day indoors my eyes felt tired and uncomfortable, but since I started wearing the yellow glasses my eyes feel so comfortable! And the eye fatigue is gone too!״Office worker · Matt J.
״Because of the kind of work I do, I’m exposed to blue light a lot, and one day my eyes started to feel really sore and dry.... I bought these out of curiosity, and now they’re a must-have I can’t do without!״Screen worker · Noah
