MORE THAN BLUE LIGHT.
Check out what Dr. Andrew Huberman has to say about the challenges posed from exposure to short-wavelength light (blue and green light) at night, and how our collaboration on Wind Down™ lens technology can help.

The Science
Exposure to blue and green light—short-wavelength light—at the wrong time of day can interfere with your body’s natural ability to wind down, disrupting your circadian rhythm. In modern life, artificial light from phones, computers, overhead lighting, and screens is one of the most common sources of this disruption.
Even low levels of artificial light in the evening can interfere with your body’s natural rhythm and reduce melatonin production, a key hormone involved in sleep regulation.
Rohkah™ Wind Down lenses are engineered to filter light within the 400–520nm range of the visible spectrum. When worn at night, these lenses help reduce exposure to short-wavelength light, supporting a calmer transition into evening and helping your body stay aligned with its natural circadian rhythm.
FAQ
How are these glasses different from traditional blue light glasses?
- Rohkah™ Wind Down lenses are designed to go beyond traditional blue-light filtering. Unlike standard lenses that target only blue light, Rohkah™ Wind Down red and orange lenses are engineered to reduce both blue light and a significant portion of short-wavelength green light—supporting a smoother transition into relaxation and rest.
- Each Rohkah™ Wind Down lens is crafted with premium optical clarity and finished with advanced anti-scratch, anti-reflective, and hydrophobic coatings. This ensures exceptional durability, reduced glare, and all-day comfort—without compromising visual clarity.
Why do AEROVault Rohkah Wind Down™ lenses have an orange/red tint?
- The blue and green light we’re looking to filter out exists in the shorter wavelength range of the visible color spectrum (around 400–500 nm). Just like with old film cameras, in order to effectively filter out certain colors, you have to use a filter from the opposite side of the color spectrum. In this case, because we are filtering blue and green light, we need to use a lens material that has a red/orange tint. So the lens actually has to be that color to effectively filter out the blue and green light.
What is the best time to wear these glasses?
- These lenses are designed for nighttime use only, the critical period of the day when exposure to artificial lights, screens, etc. can be disruptive.
- We do not recommend wearing these during the day. Dr. Huberman has shared numerous times that scientifically speaking, we actually want exposure to short wavelength light (blue and green) throughout the day to promote wakefulness and to maintain our circadian rhythm. The problem with short wavelength light comes in the evening and at night, when it can be a disruptor. These glasses are designed to filter that disruptive light in the evening.
How does it help improve my sleep?
- Artificial lights in the short wavelength spectrum (i.e., blue and green) can increase the stress hormone cortisol and suppress the natural production of melatonin, a hormone the body produces to help regulate its natural sleep cycle and circadian rhythm. By using our Wind Down™ filtering eyewear, you can reduce that disruption and give your body its best chance of transitioning to sleep.
What if I’m not sure whether these will work for me?
- We understand. This is an unfamiliar technology to many, and the idea of looking through colored lenses can take some adjustment. To help support your purchase, AEROVault offers a no-hassle 30 day moneyback guarantee. We’d encourage you to try them out and see how they feel. It may take a couple days to get used to them, but some find that they feel calmer and more relaxed even in the first session of use.
