What Wearers Are Saying:

Noticeably better mood in the afternoon

"I don’t hit that weird low-energy irritability wall around 3pm anymore. These glasses + electrolytes changed the game for me."

- Stevie W.

Actually slept through the night

"First night I wore the red lenses before bed knocked me out. No waking up at 2. That hasn’t happened in months.

- Travis J.

Works as expected, looks great

“I've had blue blockers before but wanted something that actually looked good enough to wear out."

- Ryan S.

The dopamine thing is real

"I used to be glued to my phone late at night. Wearing the reds now, I actually wanna go to bed on time. It's like my brain winds down."

- Sean K.

my girlfriend noticed

"She said I've been way more chill in the evenings."

- Kolter B.

Taking back control!!!

“Once I learned about blue light I knew I needed to do something. Found these on a facebook ad, loving them so far."

- Shelby D.

Gamechanger for computer work

"If you care about performance and actually feeling human, get a pair. You’ll see what I mean."

Better than expected

"Thought these would feel lightweight and cheap like the usual stuff. Nope. Study. Haven't worn all day yet so we'll see how it feels"

- George G.

Looks good

“I track my sleep with an aura ring, 3 days in and my sleep score is already higher than it's ever been before."

- Chris W.

Surprising benefit

“Look good and function well. What's interesting is I don't feel as dependent on coffee in the office when I wear the yellow ones. Is this normal?”

- Jimmy P.

At least I can trust you guys

Modern blue light is making you compulsive, tired, and stressed. TwentyFourth isn't just fancy frames, it's the new protocol to:

REGULATE DOPAMINE - to keep you focused, not compulsive

LOWER CORTISOL - to balance your stress, mood, and hormones

ENCOURAGE MELATONIN - so you can experience true rest

Modern blue light is making you compulsive, tired, and stressed. TwentyFourth isn't just fancy frames, it's the new protocol to:

What Should I Expect?

1 Day

The first night, you’ll feel it.
The Biosync™ lenses signal melatonin production, helping your body shift into deep recovery mode faster. Sleep comes easier, stays deeper.

1 Week

You notice your strained eyes begin to unwind, wearing your Twentyfourth's during screen-heavy days. Dopamine stabilizes. Focus feels smoother, lasts longer.

1 Month

Your sleep-wake cycle begins to sync with natural light cues.
Evenings feel calmer. Mornings are less foggy. You feel in control, less reactive.*

2 Months

You’ve cut out 90% of harmful blue light exposure. Your hormones start to rebalance. Dopamine regulation improves.
You feel much more focused and calm.*

3+ Months

This is when it compounds.
You’re no longer “managing” your energy and sleep. They just work. Your mood and energy feel natural again. You don’t just look great. You act differently. Because your biology is aligned with your ambition.*

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...

And because they look good as f***.

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.
