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 yellow 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 yellow.

Luckily, the Full Spectrum Kit allows you to take $55 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.
