1. It Saves Your Sleep

1. It Saves Your Deep Sleep

Lying in bed while your mind is running in circles? Waking up tired after 8 hours?

Studies show exposure to blue light at night lowers melatonin by 50-85%, delaying your natural sleep cycle by 3 hours or more.

Chronic poor sleep can destroy your immune system, metabolism, and mood.

Putting on TwentyFourth glasses at 6pm tells your brain: 'It's time to recover.' So you can finally wake up at 100%.

2. It Unlocks Your "Productivity Hormone"

Ever wonder why it's so hard to put your phone down? Or what causes that 2pm brain fog?

Your screen's blue light triggers unnatural dopamine spikes. Lowering your brain's baseline amount.

Over time, this destroys focus and leaves you feeling mentally drained.

Instead of more coffee or supplements - fix the the source so you can unlock smooth "flow state" focus.

3. It Calms Your
Anxious Brain

3. It Calms Your Anxious Brain

Feeling wired and irritable? Blame blue light.

Artificial blue light triggers cortisol production. This throws your body into 'fight-or-flight' mode.

This not only ruins your ability to rest and relax, but sabotages your immune system, increases inflammation, and can even lower testosterone. (ClevelandClinic).

Real blue blocking glasses let your cortisol naturally drop after sunset, allowing your body to shift into 'rest mode' for true recovery.

4. It Guards Your Metabolism

We all know the answer to a fit body is "diet and exercise" - but what if there's a hidden enemy?

Harvard researchers discovered night time blue light disrupts your body’s glucose metabolism - increasing insulin resistance and fat storage.

This makes it harder to maintain a healthy physique and may increase your risk of obesity and diabetes.

Regulating blue light helps your body properly process nutrients and maintain the body you're working for.

5. It Stops Your Eyes
From "Falling Out"

Ever feel like your eyes are gonna fall out after a long day staring at screens? Well, they're not just "tired."

Exposure to blue light significantly increases the risk of permanent retinal damage, visual fatigue, headaches, and blurred vision (The American Optometric Association).

If you care about ending headaches and saving your eyes, it's time for real protection.

6. They Actually Work (Unlike Most)

Most 'blue blockers' are made of cheap plastic and clear lenses that only filter 2-10% of harmful wavelengths (that's why they're 15 bucks on amazon).

TwentyFourth's BioSync™ lenses block the wavelengths that actually disrupt your biology (yes, they're third party tested.)

Plus, they're made with metal frames and high-resistance lenses to not only last, but look so good you can wear them out.

6. They Actually Work (and Look The Best)

7. It's Beloved, Backed, and Bundled

7. It's Beloved and Bundled

More than 3,000 high-achieving men are getting ahead with TwentyFourth glasses - which is why they keep selling out.

We offer a 365-day replacement guarantee.

Right now you can bundle both the daytime and evening pair and save $79.

Zero risk. Maximum protection. Now is the time to take back control.

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!

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.

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.
