7 reasons why
men SWEAR BY THIS 3 SECOND SLEEP HACK

Modern blue light is making you compulsive, tired, and stressed. Here's why TwentyFourth helps when supplements don't.

learn why

1. It Saves Your Deep Sleep

1. It Saves Your Deep Sleep

Lying in bed while your mind is running in circles. Waking up tired. That's blue light at work.

 

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

 

Chronic poor sleep doesn't just ruin mornings - it destroys your immune system, metabolism, and your mood.

 

Putting on TwentyFourth glasses at 7pm signals to 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?

 

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

 

Over time, this destroys focus, reduces your attention span, and leaves you feeling distracted, anxious, and mentally drained.

 

Instead of slamming coffee or popping "brain 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, finally 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.

 

The lights around you (even in the gym) are making it harder to maintain a lean, healthy physique and dramatically increasing your risk of obesity and diabetes.

 

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

5. It Stops Your Eyes
From "Falling Out"

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."

 

The American Optometric Association found prolonged exposure to blue light significantly increases the risk of permanent retinal damage, visual fatigue, headaches, and blurred vision.

 

Our eyes aren't equipped to handle isolated blue light. If you care about ending headaches and saving your eyes, it's time for real protection.

6. They Actually Work (Unlike Most)

Most 'blue blocker' glasses 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). 

 

Honestly... lighting candles and putting the night filter on your phone does more than that.

 

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 (yes, you read that right).

 

The cherry on top? You can bundle both the daytime and evening pair and save $79.

 

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

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.
