I've spent most my life laying in bed for an hour plus before falling asleep. I thought that was just my life. Now I doze off within 10 mins, even when using screens. These glasses are a game changer.

Really helps me keep cortisol low. Took my sleep score from a 60 to 90. And they look way better than the "welding google" looking ones I had before.

When I wear the orange during my computer work I feel like I can work HOURS extra! Then we put on our reds and instantly start unwinding for bed. We're waking up actually feeling refreshed instead of tired!

Artificial blue light is making you a "wired but tired" zombie.

Did you know that from 1960-1980, casinos removed all windows and added short-wavelength lighting? They did this because they knew it would trigger a wired, impulsive, "fight or flight" state. Resulting in more compulsive gambling.

Today? Your screens, LED lights, and the overheads in most businesses all emit these same exact frequencies.

You're not supposed to wake up sleepy, crash at 2pm, and scroll till midnight. Unfortunately, this is what excess blue light causes.

You're not supposed to wake up sleepy, crash at 2pm, and scroll till midnight. Unfortunately, this is what excess blue light causes.

Did you know that 248 leading scientists are calling for blue-rich LEDs to carry a warning label (PRNewswire).

Dr. Moore-Ede, Ph.D., director of the Circadian Light Research Center and a former Harvard medical professor said:

“Fewer than 0.5% of lights sold today protect circadian health."

You're not supposed to wake up sleepy, crash at 2pm, and scroll till midnight. Unfortunately, this is what excess blue light causes.

TwentyFourth enables you to take back control.

Actually Tested, Unlike Our Competitors

Look, we know there's other "blue blockers" out there. The issue is that 98% of them make unproven claims - some even lacking a blue blocking layer entirely.

TwentyFourth's aren't just designed to look and feel better, but each batch of our Biosync lenses are tested and verified to block all 400-500nm blue light frequencies.

MEET KENNETH, FOUNDER OF TWENTYFOURTH

For years I struggled with:

Sh*tty sleep
Phone addiction
Constant distraction
Low energy and motivation

I was tracking my sleep. Meditating. Working out. Building my business. But every morning, I woke up foggy, wired-but-tired. Forced to rely on stimulants to get the bare minimum done each day.

I got into fitness and biohacking, trying all kinds of supplements and routines. And sure, some helped - but no matter what I tried I was never able to fully break free from these issues.

"I'm in my 20's, I shouldn't feel like this all the time."

Then, I stumbled across a rabbit hole that would change my life...

After countless hours of researching I realized: it wasn’t my routine. It was my light.

I tried the typical clear glasses I saw some minor eye relief, but nothing more. I needed something that looked great and actually worked.

I didn't create TwentyFourth because I wanted a glasses company. I did it to take back control from a world that profits off your sickness and distraction.

These glasses were the final piece of the puzzle.

FAQs

How do I know if TwentyFourth glasses are right for me?

If you’re the kind of person who optimizes what others ignore, this is for you.

You’re not average.
You care about your inputs. You pay attention to detail.
And you’re not willing to let your biology be dictated by cheap lighting, addictive screens, or mass-market distractions.

If that sounds like you, you'll notice the difference.

Do I need both the red and orange lenses?

Ideally, you have both to fully optimize your light rhythms - but we understand if you wish to start with one pair.

If you are completely focused on prioritizing sleep optimization, go for red. If you want to maximize focus, dopamine, stress, etc. during the day while still being able to block a noticeable amount of blue light in the evening, go orange.

Luckily, the Full Spectrum Kit allows you to take $79 off your total and get both pairs!

Do I wear the glasses outside?

During the day? Preferably not. The sun is king. It puts out the perfect frequencies at the perfect time. TwentyFourth is for artificial light sources - such as when you’re indoors or out at night. Do not trust companies trying to sell you “circadian” glasses to wear in the sun. At night? Only if you want to look cool as f*ck.

Does blue light really affect the gut?

Emerging research shows that circadian disruption caused by artificial light alters gut microbiota diversity, bile acid function, and cholesterol metabolism - meaning your biology pays for your environment in ways you can’t feel… until it’s too late.

Are the lenses tested?

Of course. Our lenses are tested to ensure quality, effectiveness, and transparency. The red lenses are tested to block 100% of blue light, 99.99% of UVA/UVB, and nearly all artificial light stimulation - exactly what your biology needs after dark. You can view recent rest results here.

Are the glasses gluten free?

Well, yes. But we don't recommend eating them.
