How do I use the Nighshades?

Wear the Nightshades in the hours after sunset or whenever you’re exposed to bright indoor light and screens at night.

They’re designed to block the green and blue melanopic light that tells your brain it’s daytime, while preserving just enough violet light to keep your world from turning into a dull red haze. This makes them perfect for real-life evening activities like watching movies, going out, or winding down at home.

For best results, put them on at least 1-2 hours before bed, and pair with warm, non-melanopic lighting like deep amber or red.

How does it work?

The Nightshades filter out 99.8% of the sleep-disrupting green and blue melanopic range (425-570nm) while allowing a small amount of violet light (400-420nm) to pass through. This violet pass-through keeps your retina’s color receptors engaged so you can maintain functional color perception in the evenings, something most full-blocking orange or red lenses sacrifice.

The result: your melatonin stays protected, your circadian rhythm stays aligned, and your world stays visually clear and usable.

How soon will I notice a difference?

For most people, the difference in sleep onset is immediate with many noticing the increased sleep pressure on the first night.

Over the first week, you may find it easier to fall asleep at a consistent time and wake up more refreshed.

With consistent use, Nightshades help your body lock into a natural rhythm, making “wired but tired” late nights a thing of the past.

Precision Engineering

Our biology evolved over millions of years to live in tune with the cues and rhythms of nature. In an indigenous setting, after the sun sets, the only light you would see comes from campfires, candles, and the warm glow of embers. The Nightshades recreate that same low stimulation signal in the modern world - so you can still scroll, cook, or watch TV at night without sending your circadian rhythm into chaos.

Our Nightshade lenses cut 98.5% of melanopic green and blue light from 425-570nm, the range proven to suppress melatonin and disrupt sleep — while allowing a small amount of 400-420nm violet light to pass. This violet pass-through keeps color receptors partially engaged, restoring detail and color separation for evening activities like reading, socializing, or movie-watching.

Whether you’re under harsh LED lighting, winding down from a long day of screen use, or creating a healthier nighttime environment at home, the Nightshades keep you aligned with the natural signals your body depends on - without forcing you to live in the dark.

The Nightshade Transmission Spectra

The Nightshade lenses block nearly all sleep-disrupting green and blue light while preserving a touch of violet for color perception. This isn’t blunt blocking, it’s precision nighttime filtration that protects your circadian rhythm without sacrificing real-world usability.

Outshining the Competition

Most blue blockers either block too little to protect your melatonin or block everything and leave you in a useless red haze.

Frequently Asked Questions

How do I use my Nightshades?

Wear the Nightshades in the hours after sunset or whenever you’re exposed to bright indoor light and screens at night.

They’re designed to block the green and blue melanopic light that tells your brain it’s daytime, while preserving just enough violet light to keep your world from turning into a dull red haze. This makes them perfect for real-life evening activities like watching movies, going out, or winding down at home.

For best results, put them on at least 1-2 hours before bed, and pair with warm, non-melanopic lighting like deep amber or red.

How long will it take to see results?

For most people, the difference in sleep onset is immediate with many noticing the increased sleep pressure on the first night.

Over the first week, you may find it easier to fall asleep at a consistent time and wake up more refreshed.

With consistent use, Nightshades help your body lock into a natural rhythm, making “wired but tired” late nights a thing of the past.

When should I wear Nightshades?

The Nightshades are designed for evening use, starting 1-2 hours before bed. They block nearly all sleep-disrupting green and blue light while keeping enough violet to preserve color perception. Wear them while using screens, under bright indoor lights, or in any environment that would otherwise suppress melatonin.

Can I still watch TV or work on my laptop while wearing them?

Absolutely. Unlike overly aggressive orange or red lenses, the Nightshades maintain functional color vision so you can still enjoy movies, read, and handle evening work without losing detail or clarity.

Will they make the world look overly red or distorted?

No. The engineered transmission profile preserves a touch of violet light, so your vision feels more natural than with traditional blockers. You’ll get maximum melatonin protection without living in a red haze.

Will these help me sleep?

Yes, by blocking nearly all green and blue melanopic light at night, the Nightshades help preserve your body’s natural melatonin production. This supports an easier transition into sleep, reduces the “wired but tired” feeling, and helps keep your circadian rhythm on track for deeper, more restorative rest.

Do they come with a case?

Yes. Every pair comes with a durable protective carry case to keep your lenses safe when not in use.

Is the nose bridge adjustable?

The Onyx and Prism frames do not have an adjustable nose bridge however the rest do.

Do they work with the Sky Portal or Red Portal?

Yes, perfectly. Using the Nightshades alongside circadian-friendly lighting creates the most complete nighttime light protection possible.

The glasses block the sleep-disrupting spectrum while the Sky Portal in Deep Amber mode or Red Portal ensures the light in your space stays biologically aligned.

How long will it take to get my order?

It depends on where you are. Orders processed here will take 5-7 business days to arrive. Overseas deliveries can take anywhere from 7-16 days. Delivery details will be provided in your confirmation email.

Is there support if I have questions?

Yes. Our team is always here for you. Whether it's setup help, usage tips, or deeper questions about red light therapy, we’re ready to support your recovery goals.
